ZzZzZ UVPaint ( skinned mesh Decal+Texturing System) ZzZz

OKOK so its like adding a new property to the shader what will do the trick.

In the case that decal texture is not applied with the modified shader it will look the same as now? Because the models will also be used online and at this moment I don´t know if I will be able to transfer the decal texture data

One last question.

I see the car example, this is totally mind blowing. The thing is, how is that texture saved?
It does create a new texture file that needs to be applied to the shader in runtime? In that case, the texture can be opened in photoshop for fine tuning?

 

But how to save your work to be permanent? For example, I applied some decals on an object and I serialize the object and restart the application. Now, all changes are lost. How to make them permanent? When i open the application all decals should be there, on the object.

 

Yes that would be great so the players can generate their own skins and have them available in next session. I was expecting to save these as NPOT and be able to load them, eagerly waiting for devs answer on this XD

 

Hey guys! There are two ways to save your painted result:
UVPaint.FIX(Renderer REN,string PathToSaveImage); -this fuction save all changed texture at custom path.
And the second way is:

Code (CSharp):

1. static public Texture your_Texture;
2.  
3. void AfterPaint()
4. {
5.     your_Texture = material.mainTexture;
6. }
7.  
8. void OnLoadNewScene()
9. {
10. material.mainTexture = your_Texture;
11. }

 

I also noticed looking at videos demo images... That your decals are allways monochrome. Isnt it poasible to project decals like a grafitti? rgb colored decals?

 

Sure! You can use any textures for decals)

 

I use the code for the button:

Code (csharp):

1.  
2. public void OnSaveDecal(){
3.            UVPaint.FIX(paintTarget.GetComponent<Renderer>(), Application.persistentDataPath);
4.        }
5.  

When I restart the app, NO DECALS! What's wrong?

The png file is saved in the folder, but how to apply it again automatically. Or just I need to use IO and searching the file manually?

I did that. But now the problem is that I have no influence on the saved texture name. I can save only one texture. What if I want to save more than one texture? Texture0, Texture1, Texture2, etc.? How to save the texture with my own name?

 

Awesome then. Gonna buy likely. Looks like we all have same doubts. Me also would like to have control over texture name because now I load the skins by texture name. VEHICLENAME_skin_0 ...1... 2 etc....

 

Code (CSharp):

1. UVPaint.Create(hit.collider.gameObject, hit.point + hit.normal * 0.5f, Quaternion.LookRotation(-hit.normal), TargetHitTexture, UVPaint.DecalSize(0.03f));

I am working on a shooting range system that uses cloth physics for the paper targets. The problem comes when I ray cast to the target in a spot forward of the mesh collider. I included an image showing an area in the bottom left of the target that is in front of the collider and is not receiving bullet holes.

Edit: I just had to move the spot position further from the target, and now it seems to work.

 

Strips on the texture. What could be the problem?

 

Can anyone confirm if it is possible to save texture with custom name? or prefix or similar?
Is it possible to paint a vehicle that has multiple elements with the same brush like paint bonet and chassis each having different material?

 

Guys, there is a solution(not tested):
Texture2D bla = (renderer.mainTexture as Texture2D)
bla.EncodeToJpg(path+"fileName.jpg")

Cool, but please, can you tell me, your quad, have Unwrapped UV?

 

This happens because UVPaint use Depth Map, and z-fight appear. Tell me, which version of unity are you use

 

Unity 5.6.0f3

 

Ok, now try to find PaintPC.shader and
Change:
float Depth = sampleShadowmap( i.sh.xy, 1-i.dpth*0.995 ); //to 0.991
it must help

 

In my case the code should look in this way:

Texture2D bla = (paintTarget.GetComponent<Renderer>().material.mainTexture as Texture2D);
bla.EncodeToJPG();

There is no the path plus the file name in side the EncodeToJPG(), so where should I insert the path?

 

If the distance to the subject is greater than 1 meter, then all is well. If more, then strip.

 

I recently got the asset.
It imports and sample scene runs fine in 4.7.2 but the zombie project is a separate package and when I try to import in a clean project I get this error:


Console shows this:
Error while importing package: Couldn't replace asset C:/Program Files (x86)/Unity4.7/Editor/Data/UnityExtensions/Unity/GUISystem/4.7.2/UnityEngine.UI.dll
Failed to move asset from Temp/Export Package/ec63683a16409584f91837d740e6d867/f5f67c52d1564df4a8936ccd202a3bd8/asset to C:/Program Files (x86)/Unity4.7/Editor/Data/UnityExtensions/Unity/GUISystem/4.7.2/UnityEngine.UI.dll

Please help.

 

Ok looks like you placed this by mistake

 

The issues instead of being distance related looks more like is related to the material is has projected on because the blood on the floor just by the green surface has no stripes.

 

The zombie project almost works perfect, please polish the package.
The garage car paint works perfect but it seems it can not bake texture. And then when I launch the race I get:

RenderTexture warning: Destroying active render texture. Switching to main context.

MissingReferenceException: The object of type 'RenderTexture' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
CarController.Start () (at Assets/iRobi/ZombieRace/Game/Scripts/CarController.cs:52)

Please import it in 4.7.2 and see it by yourself, sure its a silly thing because the painting works amazingly. Also when it returns from the race it is covered in blood so it is like 99% working!

EDIT: Strange and good, I did again test and paint--> Bake--->Start and its

 

I could not find the ui in the garage and finally found the script that generates it at runtime, that is a bit strange TBH, further, is it using the legacy UI??? I can´t find the canvas anywhere. If so that is a bit disappointing.
I know you plan not updating more for 4.x but PLEASE update to 4.6UI wich is compatible with 5.x UI prior to abandoning 4.x support.

I think that it could be easy even for me, I'll try but I'm soo freaking busy, I see the buts "just" call functions, may be the palette part seems the trickiest part. Sure that for a pro like you this has to be a breeze to port to 4.6UI

 

Hi,

I can run the example scene (UV Paint Place) nicely in the editor, but I get many errors if I try to compile it in Xcode for iOS/iPhone. This is a short summary of the type of errors/warnings:

Any ideas what might be wrong would be very helpful.

@iRobi

Hi, why does my main texture darken slightly when a decal is added ?

Thanks..

 

Hey gus, sorry for delay

 

This demo are only to show, how UVPaint works, but i will try to polish this)

Hi, might be dll is incompatible. I can send you rebuilded version for IOS

It happens after update?

 

Yes, I'm using 1.7a

 

I downloaded 1.7a and son after it appears as there is an update an still says 1.7.a so may be there where some minor fixes done and versión number was kept.

 

Hi everybody,
can someone help me please.
i'm trying to spawn a decal only over one mesh. I mean that if i spawn on border of one mesh, is behind is another, each mesh receive a part of decal, but i need that first receive all of it.
Thank you.

 

Please, provide screenshots. And... If you can, part of your scene in .unitypackage

Hi! Try please write this "UVPaint.IsTwoSided(True);" before calling UVPaint.Create();
If i understand you right

 

This ocures after building project. Is it ok?
http://c2n.me/3KXEpyB.png

 

I have a character with 3 different LODs for the mesh.

I noticed that UVPaint only writes to one of them. Is an option to have it write to all 3?

 

Also, it seems that performance has taken a hit as of late.

I'm already using "UVPaint.IsTwoSided(True)" (its done once and cached)

Questions:
1. Can UVPaint.IsTwoSided(True)" be called only in the Start Function...or should it be called everytime I call UVPaint.Create?
2. Is there anything else I can do to increase performance?

Here is my create call....
UVPaint.Create(hit.transform.root.gameObject, transform.position, transform.rotation, bloodDecal, UVPaint.DecalColor(Color.red), UVPaint.DecalSize(Random.Range(minTextureSize, maxTextureSize)));

 

I vote for the performance optimization. I tried UV-Paint, it paints well on any Skinned Mesh. It is just not cheap on cpu cost, and triggers GC calls if using often.

 

Edit

 

I think I've found the issue with performance in my game. Characters that use Unitys LOD system seem to be affected by performance issues as it runs much better when I use it on characters without LOD.

Does UVPaint have to cycle thru the LOD's to find LOD0?

If this is the case, is there a way for me to specify LOD0 in the options to keep performance up?

 

I haven got your answer, so I copied my post:

In my case the code should look in this way:

Texture2D bla = (paintTarget.GetComponent<Renderer>().material.mainTexture as Texture2D);
bla.EncodeToJPG();

There is no the path plus the file name in side the EncodeToJPG(), so where should I insert the path?

How to save many textures on disk with decals?

 

I made a mesh in Blender for sculpting in Unity. I would like to use your Decal painting to it, but Unity is blocked up and I need to kill the Unity process. Other meshes work great. Could I send you the mesh for testing?

 

hi iRobi ! How to work on mobile? I build apk to testeit and found it was not working. How do I set it.

 

bla

Yeap, it happens due to the difference Unity versions.

Guys, after using UVPaint.Create(); you can manually set edtitable material to all LOD GO. Because UVPaint can not do it from box.

We hard try to improove perfomance, but now without any success((

Try to use:
Texture2D bla = ...;
System.IO.File.WriteAllBytes("C:/folder/image.hpg", bla.EncodeToJPG());

Sure!

Hmm, did you try to compile Demo scenes?

 

The model that is clicked may be missing the material.How to solve？I remember showing support for Andriod on the product description.

 

Hello iRobi . I've seen the videos where you paint the BMW , i'm making a racing game with more than 20 different cars and a system to switch between the cars , and a simple texture changer !!!! , BUT i'm wondering if i can use this asset to make the player paint any car selected and the changes will remain , and also i'm wondering if it's compatible with my scripts , please help me i'm interested

 

It seems your email on your website doesn't work. How can I contact you to send you the 3D model?

 

Yes, all right. UVPaint is support Android. Can you record some video?

Hi! Yeap, but your models must have Unwrapped UV's

in p.m

 

Hello iRobi!

Just to let you know that I just got this system, working just great for the kind of game we are trying to do.
I was testing with 5.6.0 but recently moved to 5.6.1 and when building I get 4 of this errors:

Shader error in 'iRobi/PaintOneSide': invalid vs_3_0 output semantic 'half' at line 151 (on d3d9)

Compiling Vertex program
Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING UNITY_ENABLE_DETAIL_NORMALMAP SHADER_API_DESKTOP UNITY_COLORSPACE_GAMMA

They appear on PaintOneSide (line 151) and RestorePC (Line 182)

So far it hasn't shown any problem of sorts but I guess it may be something you want to look at. Cheers and thanks for this awesome system!

 

Just got this asset. It's very easy to use.

However, I'm getting really ugly seams when projecting. Is there a way to fix this?

 

There seems to be some very visible artifacts when projecting.



These don't appear if projecting double sided.

 

I really don't know what happened.I don't know how to solve this problem.The PC side is normal but the target material is lost when the build Apk is then draw

 

Hi iRobi when i try your ZombieRace demo it works perfectly in editor but when i try to run in android its not working. i m getting this error when i try to paint on car.
