When I try to destroy a COMP with Python that contains RayTK operators, I often get numerous errors like this:
td.tdError: Operator /project1/base2/raymarchRender3D/depth_out has been deleted.
I’ve tried adding a check for the .valid property, but that property produces True and then the error still happens:
o = op('foo')
if o.valid:
o.destroy()
Strangely it’s sometimes impossible to catch the exception. For example:
try:
op('foo').destroy()
except Exception as e:
print('OH NO!', e) # <-- this never gets called
or even:
try:
op('foo').destroy()
except td.tdError as e:
print('OH NO!', e) # <-- this never gets called
This has been an issue for at least a few years.
I think maybe I’ve seen it happen when deleting things that don’t contain RayTK operators but I can’t reproduce it that way currently.
I’ve attached a file that includes examples to reproduce the issue.
