I have an interactive PDF of an assembly created back in 2018 that is in full color and where the some of parts have the transparency attributes set so bearings and spacers inside are visible. I added another part to the assembly and tried creating a new pdf with it. Although a couple of the parts are still in color everything else is now grey and opaque. I can post screen shots if anyone wants to see it. Is there a parameter somewhere to make it do what it did so well almost from the very beginning of Alibre?
The use of transparency causes some problems with 3D PDF and colours. The problem has been raised with the provider of the relevant software component, seems it's likely to take a while yet to fully resolve.
