Load mesh via trimesh object does not work.

[Byson-source]

Hi! Thanks for your great work!

I try to load mesh file via trimesh. When looking at mesh in trimesh viewer, it looks fine. But once I load same mesh for pyrender, this generates significant amount of artifacts.

Trimesh viewer

pyrender viewer:

My code is following:

from pathlib import Path

import pyrender
import trimesh
root_dir=Path(f"...")
tm=trimesh.load(str(root_dir/"scene_00009/colored_mesh.ply"))
tm.show()
mesh=pyrender.Mesh.from_trimesh(tm)

light_val=0.5
scene = pyrender.Scene(ambient_light=[light_val,light_val,light_val])
scene.add(mesh, "mesh")

pyrender.Viewer(scene, use_raymond_lighting=True)

You can find the mesh file from following GoogleDrive link:
