I was trying to use gl_FragData[n] to write multiple image outputs at once.
When I load the shader in the modules folder, I get one output. It does render the blue background of gl_FragData though, which is not a bad fallback.
Is this something that makes sense as a feature enhancement request for this shader functionality in VUO? Does the ISF aspect a limitation on this, or no? There seemed to be no compiler error.
Should I expect this to work if I write a custom node and manually create the multiple image outputs, with each frag data index writing to a different out?
