You have to adapt the Shadertoy code provided (the fragment shader) and also you have to modify the xml header of the jitter shader file (which extension is.jxs) and the vertex shader of said file in order to work properly within the jit.gl.slab object. Then, in the fragment part of the shader you have to adapt the main() function as well. In regards to function names, you can keep the names as it is, or change them. The tutorial has a very detailed walkthrough on how to do those things.

Hi Fabio. I saw your video. I would need to have a look at your Max patch (your example was made using Jitter) and see what’s the issue. I’ve tried to replicate this very same example in Max and I’m not getting the same results. Perhaps is something software and not code related. Best.

Thanks for your reply, yes.. it may be a limitation of the software since these are new practices for gitter. later I will try to see if I can receive the reflections of a shader perhaps with another software. Thank you so much 🤗

Gracias!!

Many thanks! Soundtrack is mine too. Stay tuned!
