Trimesh fails to load mesh texture for a large mesh

[easteine]

I am using trimesh to load a obj mesh that is quite large (563416 faces) with a .mtl texture. Without the texture the mesh object can be loaded but with texture the process is killed with exit error # 247. Meshlab can open the mesh fine (takes ~10s). I'm assuming this may just be a limitation with trimesh and mesh sizes.

I don't actually need to see the texture when viewing the mesh or scene with mesh.show(). My goal is just produce rendered images with texture based on camera locations.

Do you have any suggestions?

This looks like an issue from pillow.

from PIL import Image
# Image.MAX_IMAGE_PIXELS = None # Try this if next line is crashing
texture = Image.open('texture.jpg')

That doesn't seem to be a problem, my textures are 2048x2048.

Since then I've also tried converting my files from obj to glb file type instead in case it was a problem with multiple textures. As well, I tried using meshlab to save only a subsection of the mesh to see if the number of vertices and faces was a problem. Neither has worked.

import trimesh as tm
from PIL import Image

mesh =  tm.load('large_mesh.obj', skip_materials=True)
print(type(mesh.visual)) # should be TextureVisuals since your mesh has uv coordinates
print(mesh.visual.uv.shape) # should be (n_vertices, 2)
image = Image.open('large_mesh_texture.jpg')
mesh.visual.material = tm.visual.material.SimpleMaterial(image=img)

Are there any problems with these lines?

PS : sharing your mesh and texture might help others reproducing the error.
