Hi,

I followed above thread on "fading parts in Motion studies", and changing the transparency setting in appearances worked for several assemblies.

But I have a particular assembly which the above workaround doesn't work for.

The odd thing is;

The transparency value varies along the time line depending on where the time bar is (in particular between the two keys).  It's just not visually reflecting it in the model!

The part is instead it's either fully shown or not. 

I was wondering if there could be a slight difference in general settings which could be causing it?

Version: SW 2019 SP5.0

Any assistance would be much appreciated.

Thanks,

Earl.
