Hi, I spent maybe two hours trying to get something that looks like "normal shading", but no matter what I do, I don't see specular highlights nor normal shading (it's either burnt white or ambient light).
I decided to try the 3DModelLoaderExample, just to see how it's done there, and to my surprise, I can't see any of the models by pressing keys 1 to 6.
I started to connect dots, and remembered that if I try to use ofVboMesh it crashes, and for that reason I can use ofxGui. Together with issue #5409 https://github.com/openframeworks/openFrameworks/issues/5409 (ofSaveFrame() crashes on my OF), I thought... hmmm... maybe there's really something going wrong here?
Otherwise it runs fine, I'm using OpenCV, playing videos and webcam, drawing 2D and non shaded 3D graphics fine.
I'm on ArchLinux, Intel 4600 graphics, updated packages including Intel driver, i3 tiling window manager, OF from Git.
Does any of this ring a bell somewhere?
