ZzZzZ UVPaint ( skinned mesh Decal+Texturing System) ZzZz

I found two more bugs.
If the texture import setting is not clamp, the texture is corrupted.
If the UVPaint.DecalSize() has a size less than 1, the texture is corrupted.

 

Another bug:
NormalizedAlpha and Normalized_DeepAlpha does not work with SkinnedMeshRenderer. It does work with regular MeshRenderer

 

Is it possible to paint on terrain? I mean I tried it and it didn't work, but I just want to verify.

 

Hi! Sorry for delay...

Why you use Quaternion.LookRotation(-hit.normal) instead camera.transform.rotation?

Yeap, maybe. Because i use GetComponentsInChildren<Renderer>(); instead GetComponentsInChildren<SkinnedMeshRenderer>();

 

Thank you so much! I will fix all of them

It is so strange! I just checked this, and all works fine...

I think, UVPaint can do it, because terrain has Unwrapped UV (plane), but all decals will be ugly (low quality). The better solution is use mesh decals. I will add this in next update

 

Hi again iRobi
I am having difficulty achieving an effect which I think should be possible with UVPaint. Basically I want to put a "hole" in a texture (e.g. a bullet hole through a paper target).

I am using a custom shader that uses a mask image, and I am using UVPaint to draw to that mask rather than the main texture. I tried putting a completely blank/transparent image as the mask, and then using UVPaint to draw a small black circle on it. However nothing seems to happen to the in-game output. I wonder if it was something to do with how UVPaint creates the texture instance (does it support transparency?)

I am a complete beginner when it comes to shaders so I might be doing something wrong, but I wonder if you had any ideas?

This is the shader I am using (I am drawing to "_Mask"):

Code (Boo):

1. Shader "Custom/MaskedTextureShader"
2. {
3.    Properties
4.    {
5.       _MainTex ("Base (RGB)", 2D) = "white" {}
6.       _Mask ("Culling Mask", 2D) = "white" {}
7.       _Cutoff ("Alpha cutoff", Range (0,1)) = 0.1
8.    }
9.    SubShader
10.    {
11.       Tags {"Queue"="Transparent"}
12.       Lighting Off
13.       ZWrite Off
14.       Blend SrcAlpha OneMinusSrcAlpha
15.       AlphaTest GEqual [_Cutoff]
16.       Pass
17.       {
18.          SetTexture [_Mask] {combine texture}
19.          SetTexture [_MainTex] {combine texture, previous}
20.       }
21.    }
22.     FallBack "Diffuse"
23. }

Many Thanks

 

Hi! Thank you for your support! UVPaint does not yet support, but can paint on texture. Because alpha is not overrided.
Now has version which have this functional, but with some issues. After all fixes, i will submit new version. Thanx for patient)

 

Hi is there a fix for unity 5.5.2f1 the material just goes pink????

 

Hi! Sure, please send me your e-mail in p.m

 

hello there is a demand for my project .I have two boxes and I want to draw the box below. But still will spread, can not be completely blocked by the box above, may you have any way to solve this problem? How do I deal with it?

 

Hi! You mean Depth Covering like shadow? (Block Spreading by another object which cover peojection)?

 

yes How to solve the problem? Could you please help? Thanks in advance

 

I'm having the same issue in Unity 5.5.2p1

 

Depth mask functional now done and wait for submitting in store, thanks for your patient!

Please, send me your e-mail in p.m., i will send you the fix

 

Hi iRobi
Thanks for submitting. When I can download it? Or how do I use it?

 

It can appear in the store at any time... May be week

 

I want to make a quiz, and i need people's opinion.
Is this Transparent Effect useful for somebody? (video below)

 

Hi iRobi,
I also have the "pink issue" with Unity 5.5.0f3.
Could you send me (sorryone2015@gmail.com) a fix?
Thanks.

 

Done!

 

I bought asset today too and everything is pink. When will be your asset updated on store? I dont want to publish my email publically on the forum. Or can you send me new version to my spam email? exltus@centrum.cz

 

Sorry, but i dont understand, why store doesn't still approve plugin update...
Now i sent you fix, thanx for your support!

 

Hi iRobi.
Thank you for solving my problem！But after the update I found that my stroke shape has changed，
I used a circle as a decal and the previous version is displayed correctly.But now its error，
the strokes are intermittent，As shown below,This stroke is no longer round. How to solve the problem?

 

Hi! If its no hard for you, can you share screenshots identifical by it, but in old version of UVPaint?
And... Try to increase distance from DecalCreater point

 

What is DecalCreater point? You can see contrast，left picture is old version,right picture is new version:

What is the cause of the problem？

 

Spot position. You create decal from camera? Translate back camera before calling UVPaint.Create(), and after, return position:
SpotPosition.Translate(Vector3.back*5);
UVPaint.Create(SpotPosition.position,SpotPosition.rotation,...);
SpotPosition.Translate(Vector3.forward*5);
Try to increase distance like this.

And please, tell me, which version of unity are you use?

 

Unity version 5.4.1, Using RayCast function And did not solve the problem.

 

Try use -transform.forward*10 instead -transform.forward*0.01f

 

1.7a Update
Notice: This is the last version that supports Unity 4
• Added "Shadow Painting" feature. (based on depth map)
• Added Transparent shaders support.
• Added NPOT textures support.
• Added "Zombie Race" game demo.
• Added new Demo Scene "UVPaint Place"
• Fixed trouble with Repeat Decals (wrap mode:Repeat now supports)
• Removed old demo scenes.

 

Hi iRobi,

I'm very new to Unity and I'm having trouble using your awesome plugin.

What I did:

1)Put iRobi.dll in plugins folder of my project
2)On my PlayerShoot.cs script I've created a Paint() function that I run on Update() method. Here are the codes :

Code (CSharp):

1.  
2.  
3.     public Texture2D Decal;
4. private void Update()
5.     {
6.         if (Input.GetMouseButton(0))
7.         {
8.             Paint();
9.         }
10.     }
11.  
12. void Paint()
13.     {
14.         RaycastHit _hit;
15.  
16.         //We hit
17.         if (Physics.Raycast(cam.transform.position, cam.transform.forward, out _hit, weapon.range, mask))
18.         {
19.  
20.             GameObject hitGameObject = _hit.collider.gameObject;
21.  
22.             UVPaint.Create(hitGameObject, _cam.transform.position, cam.transform.rotation, Decal, UVPaint.DecalSize(DecalSize));
23. }
24. }

3) Then, on my Player prefab (where playershoot.cs is) I drag "brush01.png" (the texture I found on the Texture folder of your UVPaint folder) to "Decal" serialized field.
4) Then I create a cube on my environnement and put a box collider and a mesh renderer on it (i think I have to do that?) I also tried with a skinned mesh renderer
5) But on play, when I shoot on the cube, the camera is acting weirdly and I got the error "
NullReferenceException: Object reference not set to an instance of an object
iRobi.UVPaint.Detect ()"

Any help please?

Edit: looks like the weird camera is UVPaint Decal Service. I dont know what is this?

 

Hi! Looks like, that you include dll without dependencies. Try to import complete package.
And Important! Use models with Unwrapped UV. Cube doesn't have this

 

Alright thanks! I will import it.
Also, my question is how can I create the unwrapped uv on a model that i have created ? Im unsure about what unwrapped uv is

 

Often characters have Unwrapped UV. More 3D Editors like 3ds max support automatic Unrapping tool

I was interested in using this for an upcoming update to our PS4 title Honor & Duty but was concerned about the performance. Both web demos run pretty slow on a good PC. Can you let me know what I should expect performance wise? I plan to use this in a FPS to add blood splatters to enemy AI when they are shot so it may be adding decals frequently during gameplay. I'm not sure how this works but I assume all the enemy's can share the same texture without issue. One last question, is there any reason this wouldn't run on the XB1 or PS4?
Thanks,
Reggie

 

Hi! Web demos are ugly, and doesn't optimized (Uses GameObject.Instantiate per shooting).
Normally in gtx 650, UVPaint works with 60 fps by calling in every frame

 

Hi iRobi,

What if I want to add your plugin to an existing project? Do I necesseraly have to import everything? Can't I take the dependencies from your plugin to my project?

Thanks for the help, I just want a proper installation with my current settings

 

Hi!) You can import plugin to existing project simply, because all resources are placed in specially folder, which dont collide with other. After importing you can remove Game Demo package, example scenes)

 

I just noticed that this uses a .dll and I'm wondering if this will work on the PS4/XB1 as I've had assets before that won't work if they used compiled code.

 

I think, all must be cool, because dll compilled with only unity dependencies

 

Quick question: If I were to want to fade over time a decal texture that has been projected onto multiple meshes, could you prescribe a methodology to accomplish this?

Also, if you don't mind suggested features, I would love to see a couple of things implemented:
1. A Create overload that could take a Material and apply the channels of that Material to the applicable channels of the painted object materials.
2. The ability to use a spritesheet to animate decals.

Number two seems quite a bit more complicated than number one, but I could see myself using both of those features immediately.

Thanks!

 

Does this come with full source code ? I'd like to have the freedom to change the source code if it becomes unsupported.

 

Hi! UVPaint is more a runtime texture tool, than decal system

You can write your own shader with textures slots that will be layers

Nope, it's impossible, because UVPaint bake decal into the target texture slot of the model's material

 

No, but i can provide sources by your request

 

Cool, bought it yesterday, played around with the demo and noticed something though, there's a pretty big hit every time I paint on a mesh. I tried profiling the demo and a big hit happens inside the Painter script (the one attached to the player camera), I tried the script on a custom skeletal mesh and you can notice the hiccup happening every time I paint on it. is this to be expected ?

 

This is possible due to the fact that the depth map was added, try to use UVPaint.TwoSide(true). This can boost perfomance

Hi iRobi,

We bought your plugin and looking into your code I tried to write my own script:

Code (csharp):

1.  
2. public class ObjectPainter : MonoBehaviour {
3.    
4.        //public Texture2D Decal;
5.        public int currentTexture;
6.        public Texture[] textures;
7.        public GameObject aimObjectImage;

11.        private GameObject paintTarget;
12.        private bool isSpawning;
13.        private Vector3 spawnPos;
14.        private string textureFolder = "Decals";
15.        private Texture2D Decal;
16.  
17.        // Use this for initialization
18.        void Start () {
19.            AimEventDelegate.showAim += OnShowObjectAim;
20.            isSpawning = false;
21.            aimObjectImage.SetActive(false);
22.            StartCoroutine(PrepareTextures());
23.        }
24.    
25.        // Update is called once per frame
26.        void Update () {
27.        
28.            if(TransformGizmo.target){
29.                paintTarget = TransformGizmo.target.gameObject;
30.            }
31.        
32.            if(Input.GetKeyDown(KeyCode.L)){
33.                current = colors [Random.Range (0, colors.Length)];
34.            }/* else{
35.                current = new Color(1,1,1,0.3f);
36.            } */
37.        
38.            if(Input.GetKeyDown(KeyCode.P)){
39.                if(Decal){
40.                    current.a = 1;
41.                    UVPaint.Create(paintTarget, transform.position, transform.rotation, Decal, UVPaint.DecalSize(DecalSize));
42.                    UVPaint.ShaderPropertyName("_SliceGuide");
43.                    UVPaint.DecalColor(current);
44.                    UVPaint.Create(paintTarget, transform.position, transform.rotation, Decal, UVPaint.DecalSize(DecalSize));
45.                }
46.            }
47.        
48.            if(Input.GetKeyDown(KeyCode.M)){
49.                //UVPaint.AngleInDegrees(Random.Range(0,360));
50.                currentTexture++;
51.                currentTexture %= textures.Length;
52.                Decal = textures[currentTexture] as Texture2D;
53.            }
54.        
55.            if(Input.GetKeyDown(KeyCode.N)){
56.                if(Decal){
57.                    UVPaint.DecalColor(current);
58.                    current.a /= 2;
59.                    UVPaint.DecalColor(current);

65.            }
66.        
67.            if(isSpawning){
68.                RaycastHit hit;
69.                var forw = new Vector3(0,0,100);
70.                var fwd = gameObject.transform.TransformDirection(forw);
71.                if(Physics.Raycast(gameObject.transform.position, fwd, out hit)){
72.                    spawnPos = hit.point;
73.                    aimObjectImage.SetActive(true);
74.                }
75.            }else{
76.                aimObjectImage.SetActive(false);

84.            yield return null;
85.        }
86.    
87.        public void OnShowObjectAim(){
88.            isSpawning = !isSpawning;
89.        }
90.    
91.    
92.    }
93.  
94.  

Decals are created and applied to objects, but I am unable to remove them and use random colors.

EDIT:
I use the Unity cube primitive (not unwrapped) and your bear for testing.

I can apply decals to the cube and the bear, but I cannot remove decals from the cube, but I can do that from the bear.

UVPaint.FullRestore(paintTarget, UVPaint.DecalSize (DecalSize));

works for both.

I changed:
UVPaint.ShaderPropertyName ("_SliceGuide");
to:
UVPaint.ShaderPropertyName ("_MainTex");

And now I can apply colors to decals (the cube and the bear).

How to save all decals on teh object?

I think you should make a good tutorial with all the API and clear examples how to use it.

 

Hi! Thank you for your support!
This is tutorial "UVPaint Raycast"

Cube must have Unwwrap UV, for correct work with UVPaint.

Use UVPaint.Restore(), this is Eraser for particular remove decals from model.

Try to use UVPaint.SaveStateForRestore(), it provide you to bypass erasing your baked decals!
Good luck)

 

Hello, I use 4.7.2. I would like to paint over a vehicle that is using bumped specular shader. Do I need to use specific shader or is it compatible with Unity bumped specular shader?

 

Hi! You can just place UVPaint.ShaderPropertyName("_BumpMap"); before UVPaint.Create();
I can be wrong in names of property, but try to do this
