Hi Paul!
I’m not a Shader guru but I think the version of the GLSL doesn’t accept the Switch case.
But I think that a solution is to write if/else conditionals and will work ( If(condition){ else{…} )
PD: Thanks a lot for your immersive work. Much appreciated.
Just curious that Shadertoy works and the node is called “Make image with Shadertoy” … so at the every least the documentation for that node should say something about restructions. Shaders are hard enough to debug as it is. :-)
