Strumpy Shader Editor [Now Open Source]

Interesting tutorial on vertex shaders...so I am thinking with it, i can do bulging muscles and deforming stuff like skin...can't wait until you show some more stuff

 

Hey,

how i can modify the RimLighting shader with UnlitAlpha or SelfIlluminated Diffuse?



btw. sorry for my bad english ;-)
thanks!

 

thanks for this awesome tool stramit...

i've been digging through these 46 pages of posts trying to find more information on a 'light vector' expression.
There were some posts saying that it wouldn't work with the unity render pipeline, but 'simple lighting' materials could be used instead.
is this correct? is there no strumpy equivalent to an unreal-style light vector expression?

 

Could someone post an example of how the SimpleLighting graph can be used?

 

My attempt at rgbe HDR reflection:

Need help with reflection fresnel (see graph file in attachment)

 

Good to know, thanks. Incidentally, did you get my PM?

 

Hello,

Thanks for all this great job and posts.

I'm looking to learn shader way with your editor as main tool and as a first step I'm looking to adapt this shader into a Graph.

WindowShader

May , please, ask you a sample graph for it ?
In order to help me to start on a concrete exemple by example.

Any other advise on additional reading in order for a 'noob' like me in shader programmingto be able to use correctly the Editor will be very appreciated

Thanks a lot,
Loa

 

When i add the texture node circle red, my shader changes to pink color, which means error.
check the attached image and shader graph.

 

same problem here ;/

 

I have transparency issues as well, specifically when involving native unity transparent shaders. I have a ring going through a sphere. The ring is unity's transparent / diffuse, and the sphere is strumpy rimlighting with transparency and transparency queue active. No further adjustments or complexity to the scene.

There isn't intersection behavior for the strumpy shader, causing it to always appear in front or behind the ring, depending on camera angle.
In fact, the ring will still be drawn over the sphere when moved behind it, until it reaches a certain distance, whereupon the sphere is properly drawn first.


Despite the problems I'm having, I think this is a great and powerful asset, and I look forward to future updates. Thank you so much for your hard work and contribution to fellow developers!

 

i am trying to FADEOUT my fresnel rim lighting in the distance ( because it becomes really aliasy/artifact-riden far away ! )

isnt there an input node that returns 0 for a pixel that is as close to the camera and 1 for something that is 1 unit into the screen and so on ?! basically oldschool gl-fog !

i could make that work as a mask i am sure ! but what is that node called "screendepth" and "screendepthdiff" both seam to not do that !


actualy now that i upgraded to 3.2b screendepthdiff seams to do the trick but it says its a pro only feature/deffered rendering ?! whats up with that ? isnt old school gl fog like the cheapest effect ever ?

 

Hey stramit, quick question...do you know that fake refraction shader that you posted way back when, will that work on Unity 3 Indie? And also, is there a nice elegant way to set up a shader that will allow me to do stuff like "damage on a fighter model as he gets progressively damaged"? with bruises and cuts...

thanks man...

 

For the damage on a fighter thing I'd go with two textures, a clean one and a damage one. Then an alpha mask with various alpha values painted on it. You increase a value that you pass to the shader based on damage and it paints portions of the damaged texture by comparing the passed value to the alpha of the mask, if the alpha is lower than the damage value, paint the damaged texture, if higher paint the clean texture.

 

But it has to be procedural...i don;t want the damage to look the same every time...

 

Yes that is the rub: the model is uv mapped... so I would have to create three more texture channels for levels of damage...would a lerp node help? I am also looking at my graph to check the ALU count and it says N/A...what is up with that...? I would have to see your slider setup for texture switching... I've been using Float values since the slider bar is very touchy

 

Cool... my NI Shader is ALU: 54 TEX: 7... (sounds bad and I don't know what an ALU is). And this setup is just for fighting game models with three levels of damage (will create a simple version of this shader for other game types)... so I could use a split node and a LERP node to plug in three other textures... weird that is says 7 for textures but there are only six inputs for textures... and with this damage model set up... i would have about 24-26 textures for each fighter

EDIT: I could also have the material as an instance

 

Hi all.

This editor really rocks for me since it's not very different from what i have in Maya.

I do have one question though. I've been trying to get a transparent shader that doesn't affect the oppacity of the specular highlight. I read somewhere that you could link the specular highlight output into the alpha input, but i haven't figured out how to do it.

I want something like a fully transparent shader that shows the specular highlight fully opaque.

thanks.

 

I have a shader that I believe does exactly that... I am not in front of Unity, but you would have to set the shader to transparent and plug in these nodes:

A colour (RGBA) into the albedo node: Set it to black for better results
Copy the colour node twice you can set this to whatever colour you want.
Create two multiply nodes and plug the result into the Gloss and Specular.
Now plug the colour nodes into Arg 1 of each multiply node.
Create two float nodes and plug them into the Arg2.

If u want to use textures instead, you could plug a Texture2D and a sampler2D into the Albedo (your texture needs an alpha), the specular, and the gloss. I am using this set up for my eyes on my model

hope this helps

 

I thank you for the assist, but unfortunatly as i make the object transparent, the specular highlight still fades out by the same ammount :S

really stumped on this one.

 

make sure to set the float on the spec and gloss to 1... and name ur nodes

 

can u do a screenshot of your sgraph?

 

Yes, A scene graph would be good.

 

I got it to work with additive blending and your sugestion(black for best results and all.

This does seem to fix the specular highlight going transaprent with the rest of the object.

 

Hi everyone,

Let someone explain me how to extend a laser ray till my target . In such a way the ray should not exceed the target . Also i have used the javascript given below hence i got a "line" till my target where i cannot add a material to it .. So kindly give a javascript which should replace drawline with gameobject . (How should I replace a drawline with gameobject to add material using javascript)

var playerPosition: Transform;
var subjectPosition: Transform;
var hit: RaycastHit;

function Update () {


if(Physics.Linecast(playerPosition.position, subjectPosition.position, hit))
{
if(subjectPosition.collider == hit.collider)


Debug.DrawLine(playerPosition.position, subjectPosition.position, Color.cyan);

else

Debug.DrawLine(playerPosition.position, subjectPosition.position, Color.cyan);

}
}


Thanks in advance

 

You should make a separate thread for this question, not hijack this one.

 

How do I use the parallax node? I've searched yet can't find any examples of it.

 

Hello,

May be a starter question but, please, how do you manage to get the dynamic rendering working ?

I can use it with unity preview but i would like to use the dynamic view.

You build a web version of Strumpy ?

I'm on Windows 7 64 bits.

Cheers,
Loa

 

I warning I get here when updating a shader :

There are inconsistent line endings in the 'Assets/StrumpyShaderEditor/Editor/Resources/Internal/Temp/TempShader.shader' script. Some are Mac OS X (UNIX) and some are Windows.
This might lead to incorrect line numbers in stacktraces and compiler errors. Unitron and other text editors can fix this using Convert Line Endings menu commands.
UnityEditor.AssetDatabase:ImportAsset(String, ImportAssetOptions)
StrumpyShaderEditor.NodeEditor:Update(EditorWindow)
NodeEditorWindow:Update() (at Assets/StrumpyShaderEditor/Editor/Scripts/NodeEditorWindow.cs:24)
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

When I hit Update Sahder nothing happens in the shader viewed by unity (TempShader) even if it's updated.

If I export as all is ok.

If after I export the 'Export As' shader is updated but not the temp one.

 

I would ignore this...this always appears with my scene, but nothing is wrong...

 

If you create a repeatable crash - is the only way reinstalling?
(attaching a tex2d.a to parallax.bias / height or Infinite loops)

 

The spec and gloss don't seem producing the expected visual results. What are the values expected for the Spec and Gloss inputs? Perhaps I am not supplying the correct values that are expected by the editor.

The spec should be the intensity of the highlight and the gloss should control the spread of the highlight. Currently this is not the case. I have been unable to verify proper functionality on any type of object due to sporadic or random results. I tried both float values as well as using images in both inputs but still no good results.

The standard math used to control these inputs should be: ((Spec value ^(pow) Gloss value) * (Light vector ·(dot) Surface Normal)) + albedo. This is how it's done in UDK and it gives off some amazing results. Also, every white paper on the subject shows a similar if not identical equation for calculating the spec and gloss. Please look into this. I believe this will be the definitive jump in shader quality from this editor. The use of spec and gloss together allows for an infinite amount of different realistic surfaces property replications. What sets pro games apart from Indy IMHO.

BTW: The editor is awesome! Thanks!

 

Did you ever do this? I'm closer to than I was last night, but right now I'm taking random stabs at it.

edit: Got a lucky stab.

 

Thank you very much, stramit. I appreciate your time. I would suggest moving to a standard approach as the current legacy approach doesn't make visual sense. It would seem that the gloss factor doesn't really do much of what it is supposed to do and therefore limits the quality of the visual output and also limits the creative limits of the artist. So regardless of how it is handles, if it is non-standard... it's just not right . I feel, at the minimum, there should be a flag in the SSE that allows the user to select which functionality is to be used. Or perhaps put a custom lighting input that allows the user to create their own algorithm for handling light on an object much like UDK has.

I have great respect for what you guys are doing so please don't take this as a demand, I am merely making a suggestion. However, I do feel this is probably the most important foundational feature yet to be implemented properly. Please add this functionality . I, and many others, would be forever grateful (even if one is unaware of its power yet).

 

i am 100% with jcdied4me i was also really confused about the interplay between the gloss and the specular inputs.it was not what i am used to at all and had a really hard time figuring out vales that looked semi decent )

first thing that struck me as odd is that if either value ( spec or gloss) approaches 1 its gets totally blown out and becomes useless.

as far as i am concerned (artists speaking here) the gloss value should determine the SIZE/blurryness of the specular highlight while the spec value controls the color/opacity of it !

but to me it almost looks like they both do the same thing if i give them values at around


0.1 (gloss) 0.0001 (spec)

it looks practically identical to

0.1(spec) 0.0001 (gloss )

no matter what values i fed it i could never give it a small but strong specular highlight that you would want on something wet or rubber / plastic etc !

 

I usually end up overdriving my values to get them looking right...
