Shader Fix for M1 Silicon

[MBAnslow]

Ursina is perfect for my use case and provides precisely the simple no-fuss 3d game engine that I need.

However... the shader doesn't work on an M1 mac. I get the error:

:display:gsg:glgsg(error): An error occurred while compiling GLSL vertex shader created-shader: ERROR: created-shader:2: '' : version '140' is not supported :display:gsg:glgsg(error): An error occurred while compiling GLSL fragment shader created-shader: ERROR: created-shader:2: '' : version '140' is not supported

I found out that Panda3d suggests changing the opengl version used with a one-liner:

loadPrcFileData("", "gl-version 3 2")

This works for Panda3d but doing this on Ursina I get:

:display:gsg:glgsg(error): An error occurred while compiling GLSL fragment shader created-shader: ERROR: created-shader:12: Invalid call of undeclared identifier 'texture2D' ERROR: created-shader:14: Use of undeclared identifier 'color' ERROR: created-shader:15: Use of undeclared identifier 'color'

I assume that this is related to the use of version 140 of glgsg but I have very little experience in this area.

I am right at the start of using game engines and have a very simple use case which Ursina fits perfectly. It'd be great to have a simple fix if that is possible rather than learning Panda3d.

Can you send the whole output of your code?
