Some news, and partly success:
- jme works with the new LWJGL 3.3 build 8 (jme-lwjgl3) on Windows, OS-X (intel), Linux.
- However, the described problems with textured objects with Phong shading on Apple M1 are present.
- I did simplify the Lighting-Shader to make it really primitive, in principle, I just map the texture on the object with only ambient light, and this works!
- In my primitive shader, I removed all imports and used the older matrix vector multiplications with *.
- As renderer, LWJGL2 is switched on.
- The Shadow rendering works also without problems, btw.
- So the question is, what in the Phong shader causes the problems. I enclose here the OpenGL capabilities on an Apple M1, perhaps the better jme programmers have an idea what causes the problem.
Thanks!
