install.py uninstalls existing torch (2.8) and installs 2.7

Always a good idea to check any install scripts/reqs files first - and either manually change them where possible and pragmatic to do so, or create a clone of your venv/env and get it working there, so you don't break what you have; at least when it comes to installing 'bigger' packages/tools, etc.

Also, it's good practice to setup automatic backing up of important environments with cronjobs or some other automated backup/script tool.

Yeah, there does not seem to be any pre-built wheels for torch 2.8.0, so you might need to build it from scratch. You can update the dependencies in "custom_nodes\ComfyUI-3D-Pack_Pre_Builds_Build_Scripts\build_config.yaml" with your current versions then run install.py and it should try to build everything. That's what I'm doing right now, I'll see if it works.
