So I am making a resource pack and I wanted 3D models of blocks so I could put them on players heads. I use Mr.crayfishes model creator and I create the model but it is not a textured model. However I had put textures on it when I made it in Mr.crayfishes model creator. I asked a friend and he said that it was because I didn't have a texture map for the model.
I figured out what one is but I still don't know how to make one. Is there a way to make a model and texture in 1 program (not cubik I am not paying 20$ for a minecraft model creator). Thank you for reading this and please help me.
