No Obj displayed with sharpGL

Hello everybody,

I’ve begin to do a program in c# with sharpGL wrapper library from taking a github repository : GitHub - stevenalbert/3d-chess-opengl: 3D Chess game with OpenGL

My source (rendering + objLoader) and one of the obj I try to display are here : Source - Google Drive

When I try to load and display one obj, I can’t see it.

I don’t know why, because i’ve checked the initizialisation code…

Can you help me ?
Thank you :slight_smile:
