No color with Panda3d

Question

I realize a simple model of 2 colors (black horn with a yellow support) with Blender 3.0.0 which I export in * .0bj. When I open it with the 3D viewer I can see the colors appear. But, when I call it in Python (I use Pycharm 2021.3 and the 3D engine Panda3d 1.10.10) the model appears white. Moreover, it is no longer vertical but horizontal. See attached images.

With 3D Viewer

With Pabda 3D

from panda3d.core import loadPrcFile, AmbientLight

loadPrcFile("config/conf.prc")

from direct.showbase.ShowBase import ShowBase

class MyGame(ShowBase):

def __init__(self):
    super().__init__()

    pion = self.loader.loadModel("Models/Pion2.obj")
    pion.setPos(0, 15, -1.5)
    pion.reparentTo(self.render)

game = MyGame()

game.run()

Can you tell me how to get my 2 colors on my model with Panda3d ?

Answer 1

I dont know about obj files. But if you are using gltf or glb files then you can get the texture by doing this

1.pip install panda3d-gltf 2.pip install panda3d-simplepbr

then in the main.py or whatever

import simplepbr

inside your game class

def __init__(self):
    super().__init__()
    
    simplepbr.init()

    pion = self.loader.loadModel("Models/Pion2.glb") # or use gltf
    pion.setPos(0, 15, -1.5)
    pion.reparentTo(self.render)

after doing these you could see the texture in the model

Answer 2

I have had a similar experience with .obj files in Panda3D that had been exported from Blender. However, I found that exporting in the .dae format from Blender the texture is more likely to be preserved.
