How to specify custom terrain path without write permission to site-packages?

[jsw7460]

Description

I'm running Genesis on an HPC cluster where I don't have write permission to the conda site packages directory. When I try to use gs.morphs.Terrain(), it tries to create directories in /opt/conda/lib/python3.10/site-packages/genesis/assets/terrain/ and fails with PermissionError.

Current Behavior

When using terrain without any modifications:

morph=gs.morphs.Terrain(
    name='./my/custom/path'
    n_subterrains=(4, 4),
    # ... terrain config
)

This results in:
PermissionError: [Errno 13] Permission denied: '/opt/conda/lib/python3.10/site-packages/genesis/assets/terrain'

What I've Tried

I'm temporarily working around this by overriding get_assets_dir():

import genesis.utils.terrain
custom_assets = os.path.join(os.getcwd(), 'assets')
genesis.utils.misc.get_assets_dir = lambda: custom_assets
genesis.utils.terrain.get_assets_dir = lambda: custom_assets

Is there an official way to:

Specify a custom assets directory path for terrain without modifying Genesis source?
Use pre-generated terrain files from a custom location?
Set an environment variable like GENESIS_ASSETS_DIR to redirect terrain storage?

Thank you for the report. This should not happen. I will fix it by avoiding writing anything in Python source directly. This is a very practice in the first place.
