Thanks in advance

Absolutely! The way you'd do it depends a lot on the effect you need, but whatever you'd want to do, it's possible.

Could you please recommend me some entry point? Some example? Or specific library components I should investigate?

(sadly they use shaderc instead of naga, but it's still a start)

Thank you! Exactly what I need!
