Hello all! Hope you are doing well! I have just found out a new [edit2]modeller[/edit2] for panda3d which is easier than blender! It is called blockbench. Website link:
I use it for making entity models for my minecraft mods, but there is also an option to create models for any game engine. After your model is done, you can simply export it as a .obj file and call obj2egg on it! It has simple modelling and the texturing can be done in the program it self, with simple pixel-by-pixel texturing on the model, after which you can export the texture and call the setTexture method in panda. I have never tried setting the texture and then exporting the model, so I recommend you first make the model, export it, then make the texture and export it as well.
Hope it helps!
Note: If anyone has doubts using blockbench, just ask me in this topic, and I will clarify them as I have been using it for a long time for my minecraft mods as I mentioned.
You can also export it as a gltf file format and export it to panda however you are supposed to, but I can’t help with that bit as I have never used gltf. Sorry!
