Rendering memory limit

[avbelob]

Hello! I am trying to render 2K2K dataset via render.py. But in the process of performing the script, I have the end of the CPU memory, although I have about 80GB free space in RAM. Despite this, if I reduce the resolution of the picture to 256, everything works. Please tell me how much memory of the CPU is needed to make a script with an image with a resolution of 2048.

It seems strange. Even I rendered with 2048 resolution, it only requires 2~3GB RAM memory. Can you check trimesh==3.23.5 version??

Hi, I have the same issue here, and it seems like the code stuck here:

pers_points, pers_index_ray, pers_index_tri = mesh.ray.intersects_location(
    pers_origins, pers_vectors, multiple_hits=True)

in render_utils.py line 173 and then the memory consumption keeps going up.

Hi, I think the problem is because the rtree required by trimesh, and it can be solved by installing trimesh using:

pip install trimesh[easy]

make sure uninstall the original trimesh and rtree you installed.
