Blender and Fusion missing on Linux

#1 · 12. Juli 2019, 4:15

seems like Blender and Fusion Plugin Integrations are missing from the Linux version

is this something that needs to be done?

thank you

Yes that still needs to be done. I haven't received much requests for Blender or Fusion on Linux so I focused on other features. If the interest in that becomes big enough I could look at that.

What's the main difference here? executable paths?

cause I could take a look into this and if I can solve it I can share the changes

thanks

If I remember correctly the main problem was that I had problems to import PySide2 in Blender. If you could provide a PySide2 module, which works with Blender on Linux, it should be straight forward to adjust the Prism scripts to add the Linux support.

Hey @richardf

I'm on linux so I just downloaded this 2 packages

PySide2-5.13.0-5.13.0-cp35.cp36.cp37-abi3-manylinux1_x86_64

shiboken2-5.13.0-5.13.0-cp35.cp36.cp37-abi3-manylinux1_x86_64

append them to the the python path like this

import sys

sys.path.append('/somepath/PySide2-5.13.0-5.13.0-cp35.cp36.cp37-abi3-manylinux1_x86_64')

sys.path.append('/somepath/shiboken2-5.13.0-5.13.0-cp35.cp36.cp37-abi3-manylinux1_x86_64')

then it works on Blender, I suppose is the same in Windows

and you don't want to run it that way, in it's on process I guess.

hope that helps

That's the point where I'm stuck. On Windows that's no problem. I can execute this code in Blender:

import sys
pysidePath = "C:/Prism/PythonLibs/Python37"
sys.path.insert(0, pysidePath)

from PySide2.QtWidgets import *

qapp = QApplication.instance()
if qapp == None:
    qapp = QApplication(sys.argv)

class core():
    def __init__(self):
        self.w = QWidget()
        self.w.show()

x = core()

And this opens a PySide window, which I can interact with and at the same time I can interact with the Blender UI. On Linux this doesn't work (at least in my CentOS virtual machine). There I have to add:

qapp.exec_()

But this blocks the complete Blender UI until the QApplication closes.

I tried to run it in a separate process with subprocess.Popen, but then the process cannot import the bpy module and cannot interact with the Blender scene. If I try to execute it in a different thread in the same process with the threading module I get this warning and no window opens:

QApplication::exec: Must be called from the main thread

Hopefully someone has an idea how to run the PySide UI and the Blender UI at the same time without blocking each other.

+1 for Blender and Fusion support for Linux, also 3dCoat and Substance would be nice too, but blender and fusion/davinci are a must

I'm also interested in Blender support for Linux.
