I continue to search to use gl_VertexID
when I want to declare a version in vertex shader script, I want to declare for example
#version 2.1 (it’s the openGL version when I check with print gemwin)
but I have this in the PD_Terminal
ERROR: 0:1: '' : version '2' is not supported
Can I use a version 2 for a vertex shader ?
if I don’t declare a version
gl_VertexID is not recognized
