Hi, I did some more testing and it turns out that I can set a texel to a color with values > 1.0 just fine in the C++ code. When using image->setColor(osg::Vec4(1,2,3,4),x,y,0) before reading it with getColor, I can get results > 1.0.
Does that mean that the shader itself is clamping the values somehow? Or does it have to do with the internal texture copy from GPU to host memory? Thank you!
