Feature Request: Ability in Scripting to identify true 3D Objects in Mercury engine

Hi,

I'd like to request a feature in scripting: it would be really useful if there would be a way to identify true 3D objects in the new Mercury engine. This could be useful for a number of reasons but a very pressing issue is that those layers don't accept effects and when trying to apply an effect, an error is generated. This can be problematic when, for example, applying an effect to every layer in the comp. Now, of course, one could use try/catch but this will still internally create the error and therefore slow down the script. Additionally, I often have to check back on the layers in my scripts and when it's not clear why there's no effect on a layer where there should be one, this can cause issues. Currently, I'm using a rather elaborate set of conditions to identify whether an object may be a true 3D object (by checking the source file extension, etc.) but I think there should be a proper way to identify those objects.

Thanks for your consideration!

Best wishes,

Constantin
