Pas de couleur avec Panda3d

Bonjour,

Je réalise un model simple de 2 couleurs (cor noire avec un support jaune) avec Blender 2.79b que j'exporte en *.egg avec Yabee. Quand, je l'ouvre avec Panda Viewer je vois bien les couleurs apparaitre une fois appuyé sur "l". Mais, quand je l'appel en Python (j'utilise Pycharm 2021.3 et le monteur 3d Panda3d 1.10.10) le model apparait blanc.

Voici le code :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

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/Pion") pion.setPos(0, 15, -1.5) pion.reparentTo(self.render)   game = MyGame() game.run()

Pouvez-vous me dire comment faire pour obtenir mes 2 couleurs sur mon model avec Panda3d ?

hello,
je ne connais pas du tout blender et panda3d mais peut-être regarder du côté de blend2bam :

Why do my colors look different in Panda3D?
It is important to note that Blender uses a linear workflow, meaning all colors are converted from the sRGB color encoding to the "linearized sRGB" color space before being used for lighting and blending. After the render process, the colors in the framebuffer are converted back to sRGB for display on the screen.


Panda3D by default does not perform any color conversion, meaning that all the input colors are rendered as-is into the window. However, this can mean that colors defined in Blender will not appear the same way in Panda3D, as they have not undergone the same color conversion as Blender performs.


If you use blend2bam in conjunction with the panda3d-simplepbr package, this will be handled for you automatically. Otherwise, you will need to configure Panda3D to also use the linear workflow. This requires two steps:


Set your textures to use the Texture.F_srgb or Texture.F_srgb_alpha texture format, which automatically linearizes the colors before they are used in the rendering process.
Tell Panda3D to ask the graphics driver for an "sRGB framebuffer", which causes the GPU to automatically convert colors back to sRGB before they are displayed on the monitor. This is achieved by enabling framebuffer-srgb in Config.prc, or by adding a post-processing filter as described in :ref:`common-image-filters`.

Ami calmant, J.P

J'ai essayé blend2bam suite à ta proposition. Mais le résultat est presque similaire. Au lieu d'être tout blanc, il est tout noir.
Je te remercie quand même de la proposition.

Cordialement
