PureBasic Forums - English

Greetings! I have a doubt, I don't see in subsystem folder opengl, but it seems that the saders in PB work with GLSL. Should I use GLSL for shaders or HLSL?
I'm trying to learn shader language (a nightmare ), what should I learn, GLSL?

Both, depending on the renderer. Or use SPIR-V, you can also convert it to HLSL and GLSL.
