Hi Clement,
could you explain a bit more what you expect and what you are getting?
Do you want to blend between the different textures (AFAIK you cannot do
this unless you do another pass)? Are you expecting max, but getting
average?

Hi,
I have a problem with BlendEquations and shaders. That is the situation:
I attach several textures to my camera using COLOR_BUFFER0,
COLOR_BUFFER1, ...
I use a shader to make the rendering into this textures.
There is some values in this textures and i would like to use a max
blending between the value wich are already in and the values i affect
in the shader.
When I define an osg::BlendEquation with RGBA_MAX blending, i have the
blend result between the value in the frame buffer (background color or
ClearColor ) and the value in the shader.
What I do wrong? Somebody have a idea?
Thanks for helping
