Hmm could you give me more information? Which release did you try, on which operating system? Information about your graphics card would also be useful.
Thanks a lot in advance!

Hmm and which release of Material Maker ?
0.8
Try the latest version (0.9). It uses a newer Godot version as a base, which fixes some crashes on startup with low-end GPUs.
