Here is the problem.
I have 3 obj files. The file Sphere.obj and Torus.obj are imporeted correctly in 3ds max. The file Sphere_Torus.obj is combination of the Sphere.obj and Torus.obj and when I try to import it in 3ds max the ERROR: Invalid Vertex Index apperas.
Blender imports the Sphere_Torus.obj, but the result is:
The sphere obj is imported correctly. The problem is with the torus.
In the Sphere_Torus.obj the first defined object is the sphere, second is the torus. When i swap their places, so the torus is the first and the sphere is the second, the Blender loads the torus correctly, but the sphere is not loaded correctly.
Did someone know why this happens?
The obj files are in attachment.
you have just simply combined two export data of two objects in one file. it doesn’t work this way. OBJ format counts all scene vertices together. so the torus faces in your sample has to start from vertex 27 because the last vertex of the sphere is 26.
Denis, thank you.
Now my script works properly.
