Is there a way to change which version of blender is downloaded and installed when blenderproc is first run?

Describe the issue

I would like to use the latest version instead of 3.5.1 that gets installed by default.
I have tried using the --custom-blender-path option, but then it fails with ERROR: Could not install packages due to an OSError: [Errno 30] Read-only file system: 'INSTALLER' when checking/installing dependencies.

Minimal code example

No response

Files required to run the code

No response

Expected behavior

I would like to be able to set blenderproc up with my choice of blender version.

BlenderProc version

2.6.2

Hey @VTrencsenyi,

you could change the blender version by adapting the code here: https://github.com/DLR-RM/BlenderProc/blob/main/blenderproc/python/utility/InstallUtility.py#L82

However, BlenderProc only supports one blender version. If you switch to other versions, compatibility issues might arise.

Nevertheless, it should work to use a custom blender path. Could you please paste in the full error message you get when using the --custom-blender-path option? Is your error related to #1039? Are you also using windows?

The reason I was trying to use a different blender version is because I had a set of blender files that were created in 4.0 and older blender versions don't work with files from newer blender versions. I re-created the files with 3.5, now I can just stick to the default blenderproc env.

Thanks for the information, I will keep it in mind.
