04:02 <joseph_> InPhase: you can pull the branch and build on your machine. Currently it is using the screennormal shader, and the HEAD~1 commit is using the RGBCheckerboard shader (both from https://github.com/openscad/openscad/pull/3860). It's possible you'll find a bug I haven't encountered yet (so far I noticed segfaults when trying the builtin projection and recursion examples). To use the shaders, all four vertex-* features need to be

04:02 <joseph_> enabled. Tomorrow I'll try to add in a dynamic filename switcher. This shouldn't be too hard, but I'll need to make sure the renderer object is recreated after each switch

04:53 <InPhase> joseph_: Well I can confirm it builds at least. :) But it's time for bed. I'll have to take a look tomorrow.
