What was the problem/requirement? (What/Why)

Loading of libraries seems to have changed between Blender 3.6 and 4.2. When run with 4.2, the adaptor client is unable to find adaptor_runtime_client and openjd.

What was the solution? (How)

Adding the --python-use-system-env flag to the blender command resolved the issue.

What is the impact of this change?

Allows for Blender 4.2 support.

How was this change tested?

Tested by running a Blender 4.2 render through the adaptor and comparing the output to a expected output image.

--python-use-system-env is available in Blender 3.6 and also passes the same test.

Was this change documented?

No.

Is this a breaking change?

No
