I am following this tutorial. Here he loads on an .obj file and converts it into a model.txt which is later read and rendered. He created his own .obj in Maya. Now I tried to do the same with blender. I got it all the faces, normals and vertices. But I guess that there is something wrong with normals. Rastertek writes:
This particular .OBJ model file represents a 3D cube. It has 8 vertices, 24 texture coordinates and normal vectors, and 6 sides made up of 12 faces in total.
It says 24 normals. Does that mean he has his normal on the vertices? Because the model I created has only 12 normals. Plus they look kinda strange. They are not placed on the vertices but on faces. I had to create some extra faces by always selecting three vertices and pressing F.
How can I make blender save a normal for every vertex?
