trying to create a .md3

Hi, I'm trying to create and export a .md3 with blender. I was following this quickstart video https://youtu.be/SRtn9KO0omY
I've run into a roadblock, though. @0:51, he says to use Quads to Tris, however I don't have that option even though I'm using the same version as him. The only option I have when I search for tris is "Tris to Quads" I thought it might be "Triangle Faces" but I get this same error whenever I export my model and try to load it up in his updated model viewer. This is what I see, is this because I didn't convert the quads into tris? The model is just a cube

Yes, I'm pretty sure that happens when you export a model without any triangles. Have you tried looking for "Triangulate" as recommended in the comments?

Yup, that solved the problem. Thanks @mrwonko
