Hello all, I am working on a geometry shader phenomenon which will combine a render options write node and a fb append shader into a single node and have some questions regarding geo shaders as phenom.
Firstly, I have found another thread where Bart hinted at there being some recent bug fixes regarding geometry shaders in phenom and I would like to know what are the existing caveats and affected sw versions.
Second, I would like to know how to chain two geometry shaders together in a phenom. Ideally, the render opt shader would act as root, with the fb append shader an input, so that I could enable and disable evaluation of the fb creation within the options via switches. Both shaders do their work during init, and so I am a unsure which way to chain them together: Is there a 'message' or 'shader' type parameter which I can use to force the parent to evaluate the child node? What is the typical way to chain geometry shaders together (if possible)? I am not making any calls to geo_shader_append, in fact, the shaders are (more or less) pass through.
Thanks for your time, r
