I added schematica mod to my small modpack for 1.12.2 and the game crashes whenever I have a schematic open and trying to place blocks. I also just see the outline but nothing else. Here is the crashlog: https://pastebin.com/LmN9h7uG

Try disabling VBOs in the settings.

Thank you so much, that fixed it.
