How to apply a shader with model regular color, texture?

[william_shih]

Hi,

I use the reflect shader on my object. But it remove model regular color, texture.

I wish to apply a shader to make it more colorful, not replace it.

Is it possible?

Before shader

After shader

Hello Willam,

Yes, from a technical point of view, it is possible but the best solution is to modify the texture itself.

Generally, we use the shader to have dynamic effect in Experience.

Shader is a program sent to graphic card (GPU) calculate in real time and at each frame.

So for a performance reason, it is better to modify the texture in an image editor like photoshop or the gimp.

If a shader is needed, for example, in GLSL programming shader language (used in Vuforia Studio), we can add a light to modify texture rendering.

An example here :

wood gnerally isnt reflective, so it doesnt make sense to have reflectivity here.

but otherwise, you can create shaders that will simulate reflectance over a textured surface - you end up needing multiple textures defined.

its a complex, advanced usecase, but it is possible

here's an old example showing multi-texturing - https://www.youtube.com/watch?v=IOh_iUTXLpU
