ComfyUI Venv installer with Python3.12 and installer for Comfy 3D Pack +fix

https://github.com/cheesecakejohnsonturbo/VenvComfyuiComfy3Dpack/tree/main

This is a .bat to install ComfyUI using a venv environment (Requires that you install python 3.12 as it is required by Comfy3DPack)

Once comfy is installed, copy the 2 extra bats in the custom_nodes folder and run VenvInstallComfy3DPack.bat

If the last stage fails, run VenvInstallComfy3DPack finalize when failed.bat but it probably won't be necessary.
