- Is there a way to change blend mode attributes for gemhead objects?
Ie force a renderchain to render with one of the 7 source and 7 alpha blending modes that should be available?
The [alpha] object has the basic transparency function. Rolling your own around GEMglBlendFunc might work although the messages for src and dst are floats, which might require looking at the GL headers to get those values.
that is what we have the [GLdefine] object for: convert GL-preprocessor definitions into their values, eg: GL_ONE_MINUS_SRC_ALPHA into 0x0303 (which is then output as float "771.0").
