[SOLVED] -Get Value From Shader Effect


Recommended Posts

We use material.effect.setFloat and setTexture so on an so forth... Is there a way to GET a rule from a shader... Unless i am just stupid and don't see it, again :)

How do or can we event getFloat on a value that we can calculate in the shader... or even some present GLSL output property we can read ???

You can access the pixel output with engine.readPixels after the rendering.
This is how the HDR shader works by calculating luminance:
