Modeling with triangles

Hello to all, thanks for reading this and hope someone can help me :slight_smile:

I just recently wrote a little obj file importer to OpenGL and want to draw everything with triangles for performance stuff. Also I have some blender files which I export to wavefront obj files to use in my application, but blender export the model faces some as triangles and others as quads, for example: f 1 2 3, f 5 9 7 8…

Is this related with how the model was created?
Can I ask blender to export the model in triangles only? I saw the option “triangulate” on the export window but doesn’t change anything if I enable it or not…

Thanks for your time.


You can convert all quads to tris by going into edit mode and pressing ctrl T.
