Team colors

[dcversus]

Hi

I'm making a game where need use many of the same models in which the same texture, that has transparent. This transparency should be replaced with team colors. When I import model I set

players[0].meshModel.material.diffuseTexture.hasAlpha = false;

All transparent replaced with black color. How do I change this color?

Thanks in advance!

Hi,

You cannot change the texture color directly in Babylon, but you can change the material emissive color or diffuse color.

players[0].meshModel.material.emissiveColor = BABYLON.Color3.Black();

Moreover, if your characters all use the same material, changing the color for one will change the color for every one. Be careful, and try to clone() the material each time you have a different color.

Thanks for the answer.

When I use emissiveColor becomes not so necessary

 

I need to replace certain parts of the texture to another color like this (I manually painted texture):

 

Maybe can use a dynamic texture? But I do not understand how

I am not sure it will actually work... If you define something transparent, it will be transparent, meaning no color will be displayed underneath. (I might be wrong thou  ) 

I think you will need an extra object after the transparent texture to display the color. Or build a custom shader that does that.

Hello,

 

if you want you can either use different texture files with all the color OR you can use two objects like Raanan mentioned OR you can use decals

Different textures difficult to use, can be a lot of teams.

I do not know how to make an object with a different texture after transparent, In my model, it is difficult to do?

I tried to use a decal looks like the emissiveColor, decal can not be under the texture, right?

I liked the idea of a shader, you can help write a shader that would replace one color to another for a single mesh???

Decals can be used on top of emissiveColor:

And yes decals can be under a texture

I was not able move decal with character (charapter have animations) and place it under texture. 

 

The decal can be moved together with the animation of the skeleton?

I decided to the task of with the use of shaders! Thank you all for answers and advice, here's the code pixel shader:

#ifdef GL_ESprecision highp float;#endifvarying vec2 vUV;uniform sampler2D textureSampler;uniform vec3 color;uniform vec3 replace;void main(void) {  float r = texture2D(textureSampler, vUV).r;  float g = texture2D(textureSampler, vUV).g;  float b = texture2D(textureSampler, vUV).b;  vec4 pixel = vec4(r,g,b,1.0);  vec3 eps = vec3(0.1, 0.1, 0.1);  if( all( greaterThanEqual(pixel, vec4(color - eps, 1.0)) ) && all( lessThanEqual(pixel, vec4(color + eps, 1.0)) ) )  pixel = vec4(replace, 1.0);  gl_FragColor = pixel;}

Hope this helps someone)
