*EDIT I just read a post about how someone needed an Open GL 2.0 version, looks like I might have the opposite problem? not sure, any advice welcome. 

I get these errors in the debug every frame when I do any action in the modeller. I also cant build on the mesh, It says its the openGL 2.0 that doesn't allow it, I'm not super knowledgeable in the coding department but maybe make a build using OpenGL 3? 

the program stops responding and then seems to start again after it gives up trying to create or retrieve the mesh data(?)

I've been having a lot of trouble using the program because I can only draw on the walls, and come to think of it its definitely because of this haha, This program is so cool and I really would like to try it out at full potential !

- the errors

ERROR: _create_list: Condition ' arr.size() != VisualServer::ARRAY_MAX ' is true.
