Installation issue: no Mitsuba Import/Export options

[gioarma]

Hello,

I'm on a Windows machine and I'm having troubles making the plugin work. I think I have setup everything as indicated in the Wiki, but when I go to File -> Export, i see no Mitsuba .xml option, even after restarting Blender several times:

To setup the plugin I had to compile mitsuba and use a custom Mitsuba path because the plugin was not failing to automatically load the Mitsuba package:

So, I compiled mitsuba, which correctly works, and manually specified the mitsuba3/build folder (is this correct?).

Now I have no errors after restarting Blender, but I cannot see any Mitsuba export option, so I guess there is still something wrong. Can anyone tell me what I might have done wrong? Thank you!

Which version of blender are you using ?

[gioarma]

It's version 3.4.1

For blender 3.4, you will need to run blender from a command prompt, using the --python-use-system-env argument. More details are given in this comment.

Yes! running the following on the terminal solved the issue!

"C:\Program Files\Blender Foundation\Blender 3.4\blender.exe" --python-use-system-env

Which Blender version should I use to avoid having to run it from the terminal?

Versions of blender from 3.5 onwards use this flag by default. Unfortunately, this seems to have broken the addon. We're trying to resolve this issue but it currently simply doesn't work.

The best I can suggest for the moment if you want to avoid running it from the terminal is to modify the command that is run by your blender shortcut (by right-clicking on it and going to Properties) such that it includes this argument.
