Strumpy Shader Editor [Now Open Source]

Yes u can. use lerp node.

SSE does not support Unity 4 I think.

 

Did this node ever get added? If not, does anyone have an example of how to rotate a texture/uvs?

 

You can do this with the split node. Gives you access to all the channels, don't be confused by the x,y,z,w as they just translate to r,g,b,a respectively.
I created a shader to test it out, when I'm on my pc I'll upload the graph.

edit:



So yeah as you know i'm just pulling the R and G channels out from the tga and plugging it into the spec and gloss and i've added a slider for the gloss for some extra control.

 

It's a real shame that this doesn't work correctly with 4.x, it seems like 4.x has gone backwards rather than forwards.

 

Hey everyone,

So I'm relatively new to unity, and extremely inexperienced when it comes to shaders. I have been using the masked tint - vertex lit shader here: http://http://wiki.unity3d.com/index.php/Masked_Tint. I am setting my vertices to a color based on a tag, and then this renders the same material on different objects depending on said tag (I'm not sure if this is the right way to go about this??) Anyways, I am hoping to add some shine or light reflection like the built in mobile/vertexlit-directional light only shader. I cannot seem to add any sort of effect to the masked tint-vertex lit shader. I've tried everything from adding specular, diffuse, etc type lighting (or effect?). I found a few posts that led me to the strumpy editor, but due to my inexperience I'm having a hard time recreating the shader I'm currently using, more or less add some light reflection to it. I'm hoping someone could point me in the direction of how to at least approach writing this type of shader, assuming its possible to do it like this.

 

hi,Everyone

I make shader for different platform,my shader have reflection,which required shader model 3.0,and some low mobile device like micromax my shader not working,how to automatic switch shader according to graphic card?how to add subshader?

Dev

 

Hi All,

first of all thanks for this great tool.

I also have a question, maybe you can answer it: I would need 2 mirrors facing each other on a corridor. It means that - in real life - they would make'infinite' reflections; of course I don't need that in Unity. But - for example in 3ds Max I can set limitations for the number of reflections. I would like to make something like that, but I have no idea is it possible to make it in Strumpy or not.

Can any hardcore user tell me if it is possible or not? I just would like to have 2-3 additional reflections to make it more realistic.

 

Hi there,

How to rotate cubemap in SSE? please help. It's for car reflection to Android. If someone has another idea for this please tell me



that's my shader graph


Thank you
Sorry for my bad English

 

Hey there friend, I already figured this out... Nice to see it works in Unity 4... btw, in your graph, you don't need an UnpackNormal... use a Tex2DNormal

 

I am waiting for Tim to tell me if I can add to the strumpy editor Git. (Tim if you want you can add the parts you like from the files below) But in the mean time if anyone is working on huge graphs and find the editor bogging down, I have reworked the OnGUi function and made it possible to disable the Undo/Redo capture, which can cause a couple second lag. You can toggle it back on intermittently to capture at certain times. I also added scaling of the graph being drawn so you can have more on the screen at once. I also added a button to collapsible the settings panel (again so you can see more nodes on the screen). I also added some functionality for people on laptops that do not have a middle mouse button. If you feel like you need this you can get the files at the bottom of the page below. There is also a quick explanation of shortcut keys.

Download files can be found at the bottom of the page below.

Btw, I love the strumpy editor.

 

Hello all,

I'm having some trouble with a shader and hope to go about recreating (and inevitably fixing it) in Strumpy. I'm trying to make a vertex lit transparent shader for a smoke particle effect. The problem I'm running into seems to do with how the vertex lit shader and the particle billboards work, I think. From one side it looks fine (decent), but if I move to the other side of the smoke, it's not lit at all. The light source is attached the the player controller, so it's definitely moved to the other side.

I'm thinking if I made a vertex lit shader with view direction, it'll make sure the normal spun around the right way when facing the camera? Any thoughts?

Here is an example of what the smoke looks like with the default Unity particles VertexLit Blended shader


Here is how it looks with a shader I wrote by piecing parts I found from other shaders


And finally, for some reason...the Normal Direction on the particle itself, when switched to 1 makes it more visible (gets rid of the dark spots) when looking at it...though I thought 0 was supposed to be facing the camera, not 1


This is what my shader looks like. I can set up the main stuff like diffuse map, color, etc etc in Strumpy, but I'm not sure how to do vertex lit or view direction.

Code (csharp):

1. Shader "Custom/ML_TransVert2" {
2. Properties {
3.     _Color ("Main Color", Color) = (1,1,1,1)
4.     _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
5.     _SpecColor ("Spec Color", Color) = (1,1,1,1)
6. }
7.  
8. SubShader {
9.     Tags {"Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent"}
10.     Tags {"LightMode" = "Vertex"}
11.     Cull Off
12.     Lighting On
13.     ColorMaterial AmbientAndDiffuse
14.     ZWrite Off
15.     ColorMask RGB
16.     Blend SrcAlpha OneMinusSrcAlpha
17.     AlphaTest Greater .01
18.     Pass {
19.         Material {
20.             Diffuse [_Color]
21.             Ambient [_Color]
22.             Specular [_SpecColor]
23.             }
24.             SeparateSpecular On
25.         SetTexture [_MainTex] { combine texture * primary DOUBLE, texture * primary  }
26.     }
27. }
28. }

TL;DR - I'm trying to set up a Vertex Lit Alpha Shader that goes off View Direction for a Smoke Particle - I'm not even sure if it'll fix my issue though.

 

They said this was open source. How do I see the code?

 

Did you read the first post ? ...

 

Were you ever able to get this to work? If so how? I tried multiplying the object2world matrix with the normal vector and view vector but nothing seems to convert it over to spherical mapping.

 

I would like to know how to recreate this MatCap shader in strumpy as well, right now I'm struggling with definition how to map ball lookup texture with nodes so it color mesh properly...
Any help is welcome.

 

greetings guys! I'm CGartist and I had been searching the way how to use custom lightmaps with custom UV2, unless I got it with SSE! see the result: strong lightmaps which everyone needs!
BUT it caused serious fps fall on mobile platform! perhaps SSE generated too hard code. if anyone who may some kind of codding would be so friendly and would optimise/recode this S*** for android, share it in this thread? I attached shader and graph screen below
https://dl.dropboxusercontent.com/u/84629/lightmapped.zip

 

Out of curiosity how exactly did you get Strumpy to work without issue using Unity 4.x?

Checking out the repository it seems there have been no new commits since April, and would be quite a shame if people were doing their own private work to make Strumpy compatible with Unity 4.x and not pushing their fixes as a branch for others to access given that it was all offered openly in the first place.

 

Sorry, but how to switch on the preview window, this tab is missing...

 

hey everyone, I've tried looking for help with eye shading but I've come to an impass. My main goal here is to just move the built in highlight, which i've been making by basically inverting a rim light, and shifting it to be in the upper right corner of the eye, instead of the center. I tried adding x, y, and z to the camera, but then it only shifts well at certain distance, and multiply doesn't seem to be getting me anywhere, are there any other tips for 'shifting' the view by an angle? Thank you.

 

Hey folks,

i was just wondering if anyone had any kind of splat map example or shader that would perform well?

Currently using Terrain for mobile but what I would like to be able to do is set a grass texture to a different UV so it will always blend between other orientated UVS.
Terrain for mobile supports up to 4 textures so this is the number of textures id be looking for.


if anyone has any resources or links it would be greatly appreciated!


Cheers

 

Will have a version For 4X?
need support for directx 11

 

I have managed to get that working but I have really obvious seams on the model - i assumed that the image would be Uv'd according to the view direction?

 

I have managed to get it acting like a sphere lit objecy - however I get seams from the Uvs, but i thought this should be camera dependant and not rely on the UVs?

 

As far as I know:

Strumpy does work with Unity 4x.
Strumpy does not support Dx11.

(fixed)

 

It does, as long as you enable it and you have a dx11 GPU.

 

Typo! My bad... Tired.

If you look at this page:
docs.unity3d.com/Documentation/Components/SL-ShaderPrograms.html

... you will see the following:

Rendering platforms
...
d3d11 - Direct3D 11.

The warnings you are getting:
"Shader warning in 'ShaderEditor/EditorShaderCache': Program 'vert_surf', implicit truncation of vector type (compiling for d3d11) at line 28"

... is compiling for d3d11, which is not, afaik, supported by Strumpy.

 

excuse me now can we use strumpy in unity4.1.5 or not??

 

I'm using it in Unity 4 1.5 right now so... yeah it does work.
That and I made my first few basic shaders with this such as a simple hologram effect. Keep it up Tim C!

 

What I was trying to say was that strumpy currently does work with Unity 4, but not with DX11.

Strumpy does work with Unity 4.x

Strumpy does not work with DX11.

I'm not sure if it will be updated to DX11.

 

Strumpy doesn't seem to work for me in 4.x, even after I disable dx11- is it because I have a dx11 gpu?

 

hello there, can i somehow add as public the fog options of shader

 

I would assume that you could fallback to something other than DX11 specific material. Shaders written by hand and built in shaders should work on your system, no?

Can you tell us how this fails on your system?

 

Hello! I'm trying to make translucent shader - imagine leaves lit by sun. I think that I need to get light direction. If anybody could explain, how this kind of translucent effect can be approached, it will be cool. Thank you.

 

Not updated for over 2 years!

Is this abandoned?

 

Well, it is open source! So, it's only as abandoned as you want it to be! (~.^)

I'm unclear what improvements, if any, have been made.

Have you checked out the repository?

https://github.com/stramit/SSE

 

how hard would it be to setup this editor to take advantage of the recently published skyshop?

 

As i got quite annoyed with the warnings coming from the shaders made by SSE i played around with the shaders. I removed the "out Input o" from the vert part and founded that it no longer generated the warnings and the shaders work in dx11. I dont know what for consequences this has. If somebody would explain, that would be nice.

http://pastebin.com/VRxbarsC

To apply this sort of fix, replace your ShaderTemplate with the pastebin link above. You can find ShaderTemplate easily by searching.

 

I'm trying to make a couple shaders so that if my model is occluded by something, the occluded parts are rendered with a solid color. This almost fully works, however the problem I am having is that it even renders the color over parts of itself that it occludes. I'm not sure why it would do this, as the highlight shader uses ztest greater, so if I understand correctly, the pixels from the first pass written with the base texture should be equal, so as a result should not render. Anyone have an idea what might be wrong?

 

great work.

 

The solution to these warnings given by the documentation, is to add

Code (csharp):

1. UNITY_INITIALIZE_OUTPUT(Input,o);

And indeed, when you add this to the vert function in the shader template, and re-export your shaders, the dx11 compiler warnings go away, so this seems like a good solution.

I've submitted a pull request for the change.

[Edit] The repository has been updated. You should no longer get these dx11 warnings with the latest version.

 

Yeah nice, I also had this figured out with the initialize output function but i forgot to post it here , Great to see that the repository has been updated.

 

I'm attempting to create a comic shader, halftone and all that. I've got the halftone part working, the problem is that I've used fresnel to control the gradation of the halftone, multiplying it against the halftone pattern before hitting it with a step to sharpen the halftone. Is there any way to access the lighting, I suppose the luminance of an asset on the pixel graph, so I can have the pattern show against a directional light?

Secondly, any thoughts on an edge detection shader, to draw an inked edge inside the geometry, not a projected edge like the toon shader? Surely someone's accomplished that in Strumpy?


Thanks,

Bryan

 

Hi,
Im an artist (so no real shader script experience) I love this tool! but I cant get anything to show in vertex lit other than black?
any ideas?

Thanks!

 

I haven't tried creating vertex lit shaders in Strumpy Shader editor (I guess you could output to the color, in the vertex graph, but you'd have to do the lighting manually, and that wouldn't combine well with the rest of the generated surface shader), but you could make it fall back to a built-in shader, for devices that don't support your fragment lit shader.

To do that: go to the settings tab in Strumpy Shader Editor, and under 'Culling and Depth Settings' check 'enable LOD'. You can check the documentation to get an idea of appropriate LOD values. If you have an appropriate fallback shader (Also under settings, right underneath shader name), it should switch to that when you switch to the Vertex Lit render path or when you reduce the LOD in another way. (Although oddly enough, the last time I worked with this, I could only get it to work correctly for the 'Mobile/VertexLit' fallback.)

 

Hi RC-1290
Thanks for the reply, I have tried all sorts of combinations but unfortunately I dont have enough experience to work out if this is even possible with the strumpy shader editor or if im just not doing something right?
Ideally I need a shader that will work with vertex lit camera settings and openGL es1.1?
All im currently trying to do is create a simple texture blend shader with a mask....

Is there a way to use vertex colors in the lighting graph? I'm wanting to use it for Ambient Occlusion where the lit bits have no AO and the shadowed bits have full AO.
Or is there a way to do this in the pixel/lighting graph already?

EDIT: GTA IV and Fuel uses this kind of effect, though Fuel is using a texture instead of vertex colors.

 

I used the tool to create a shadder recently that used the 4 vertex color channels to blend splatmaps as an alternative to the built in terrain engine. you could probably do something similar to a lightmap

 

So strumphy now works in unity 4 with direct x 11? so i dont have to do nothing and just downlaod free from asset store? wil be huge if this nwo works on directx 11.

 

Hi guys, I have posted a Pm to the developer but no response yet, so I'm posting it here and ask for your idea, please answer :

-----------------------------Posted Message----------------------------
Hi Tim
I had Shader Fusion and was looking in it's code, the guy who developed it, is putting some tags inside the shader file so that the visual editor can load it later on, in other words, it's not able to open and edit anything that is written by hand or found on web.
is your editor able to open any shader that is NOT made by your editor?

also, I like reverse engineering great stuff like yours and I make videos on you tube about them, considering that your project is open source, would you mind if I start such a video series on your project? (with credits for you in videos off course)

also if you let me, considering that your project is already written in c#, can i make the dll version of it with the video series?

also i didn't check the complete list of nodes you support, is there any difference in supporting nodes with shader fusion? if so, can i compare and add what is missing?

thanks.
-----------------------------------------End of posted message---------------------------------------------

so what do you think guys?

 

what videos you are talking about buddy?
