My compositor is looking for data that will help him selectively mask certain parts of an animated, deforming, face. In the past, I have sent other compositors vray sampler info render element set to world or local space and that was enough, but I can't confirm whether that was suitable for deforming geometry. As it stands, all the settings I have tried are not suitable, as the sampler info doesn't seem to track with the geometry, rather, it provides static numbers which the geometry 'swims' through. Is this the correct render element to be using?

Could you elaborate more on what you wish to achieve, on what basis would that data be collected? A visual example would be most helpful. -

This looks to be exactly the thing I need, but in Maya. I'll give it a go in Max and see where I get. Thank you so much.Comment

If you use a uvw map modifier and set it to xyz to uvw mode it'll make coordinates that you can put in an unused channel and then have the sampler info element use the same channel. Depending on how your character is animated, you might have to collapse your modifier stack to make sure that the values are only calculated once and brought along with the deformation - for example if you have a rigged character, putting in the uvw modifier underneath the skin modifier would work.Comment

Oh sorry, I totally forgot I was in the Max forum. There's a discussion on how to do the same thing in Max here, including a suggestion from Vlado: https://forums.chaosgroup.com/forum/...ference-passes
Alternatively, if the face is properly unwrapped you should be able to just give them a simple unfiltered UV render pass. Not ideal, but it'll give them all the data they need to place a custom mask on the object.Comment
