Crashes whenever converting material to cycles

[narbartor]

This problem happens whenever I convert the material for cycles. It doesn't happen every time, it just happens whenever it feels like it. There are times when it crashes only once and is fixed the next time I open Blender. Other times, I have to do it several times because it crashes every time. Even times where it just doesnt crash at all, but the next time I use the model, it crashes.

It's not something that just happens with a certain type of model either, happens to all models I use

Yea, you might check #56 to see if there is any solution works for you. I currently can't fix this issue, sorry. :cry:

However, if you only want to use Cycles, you could try modifying mmd_tools\core\material.py as following (and restart Blender) to make mmd_tools use Cycles shader only.

FnMaterial = _FnMaterialCycles
if 0 and bpy.app.version < (2, 80, 0): # <-- modify this line to disable/enable BI function
    FnMaterial = _FnMaterialBI

And then you can change to Cycles, and import a MMD model, cycles shader should be there, no longer need to convert material to cycles. And see if there will be any crash. :)

Sadly, it seems to still crash

You might try disable mmd_tools and only import some FBX models (Open Blender -> Change to Cycles -> Import FBX file) to see if there will be any crash, this way we can know if it is a problem related to 'mmd_tools`. Thank you. :)

It may be a problem on my computer because I use an xps importer and it doesn't crash when I change the materials to cycles. And in my laptop, MMD Tools doesnt crash Blender when I do it there.
