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

Hello
I have a question about shader I search to work with gl_VertexID in .vert script. Some one have an example to implement this in .vert. With gl_VertexID, you can have an array of vertex with no input array for VBO and you can detreminate in real time the size of VertexArray with no latencies. I know that we can use this, but I have difficulties.
best regards
