Whenever I reimport, I always get the error:
The instruction at 0x00007FF6DADBB719 referenced memory at 0x00000000000000000. The memory could not be read.

Any ideas?

Hi,

I am assuming that you are using the Blender Pipeline plugin by soupday; If so, I have not had any
issue import/exporting characters with version  4.02 of CC4, 1.0.4 of the CC3 Blender Tools and
1.3.8 of the Blender Addon.

I could be that a texture or some other item in your GPU is being reference by both programs and one of
them is locking read access to it. It is a common thing for programs to do to prevent race conditions. Try
closing down Blender before importing back into CC4 to see if that may be the issue

A successful import screen

Thank you! That worked and prevents the crash that happens.

Now what I'm finding is that, despite me selecting the relevant updated .obj and key for the target morph, it appears not to result in anything (nor do I get the import screen you linked above).
