Model not showing up

Ok, so I took car model from beamng.drive and simplified it. When i spawn the car the model wont show up. Since i thought it was too complex i took the cube in blender and it still wont load
I dont think its a problem with lua because i took an already made addon and swapped the model.

-thanks

Well, now its an error

Help?

Any like red text in the console when you spawn in or spawn it. Shouldn’t show an error since it has little to no lua in it. QC checks out? VTF’s and VMT’s name are good? Im not a pro modeler but I know something and errors. Could help out any pro modelers who come in.

Everything is good, its already a .mdl file so qc is fine. Theres no vtf tho so ill check
