Hi, In my render I use multiple render targets normally, but when I am drawing with blend activated (blend in fact works) multiple render targets seems not works, values seem that are always discarting, why?
Are you using dual-source blending (a blend function using one of the
*_SRC1_* factors)? The maximum number of draw buffers may be lower when dual-source blending is used; the limit can be queried via
GL_MAX_DUAL_SOURCE_DRAW_BUFFERS, and isn’t required to be greater than 1.
I am using this value:
glBlendFuncSeparate(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE, GL_ZERO)
I dindt know that this parameter could change MRT
My apologies I misconfuse your response, no I am not using two different output sources for alpha color.
