I can’t get the example tessellation shaders or the Lux tessellation shaders to work on OS X, despite the documentation seeming to indicate that they should. I also see nothing but unanswered comments from others who have tried. Is the documentation on this just wrong or is something broken with the shader compilation?
I support tessellation on OSX in MegaSplat, so it’s likely just something wrong with those shaders.
Ok, I’ve been following your thread anyway, even though I don’t actually have a use for it right now, so I guess I’ll be buying MegaSplat at some point and looking at the shaders. Thanks for the reply.
In case anyone else ends up reading this MegaSplat’s shader didn’t work either.
Sent in the bug report (Case 889352) but I haven’t had much luck over the last few years having anyone look at them.
My machine specs are MBP retina late 2013 w/ Intel Iris 5100 GPU. All the documentation I can find says it’s OpenGL 4.1 and it seems to compile the shader to that target, the tessellation just fails.
