Object Properties Visibility not Controlling Render

[DGuillen-BD]

I am having an issue where I am attempting to animate the visibility of objects for an animation. The problem is that when the visibility of the object is set to 0.0 the object still renders. I have changed the properties to be by layer and also attempted using curve editor and adding a visibility track still to no avail, the objects still render as normal without being opaque. Please help!!! 

I have also attempted changing the renderer from ART to Mental Ray and still nothing! Screencap is from the render in progress, the block shown mid left is supposed to be at about 0.2 visibility and still renders as 1.0

Hi gmote. AFAIK you can't animate the "Renderable" property (at least not without coding). But you can animate the mix value in a blend material. So take a look at my earlier post (nr. 12 from the top), and see if this could help you.

Hope it helps

Blend materials aren’t compatible with Arnold renderer!

[PROH]

Not near Max right now, so I can't test it. But if Max's blend material aren't compatible even with the "legacy support" (can remember the exact wording) activated, then I'm sure there must be some sort of mix-material or layered material that can do the same.

I have legacy support enabled. No dice.

Here’s what I’m trying to do…. So easy in Mental Ray. Importance of MR or
Arnold over Scanline is having AO darker shadow directly under car… not
possible with one pass in Scanline.

PS:  It took me days to figure out how to apply a shadow matte with AO to a plane on the ground in this scene to receive shadows.  No simple explanation on Autodesk or Arnold sites except for Maya users.  Now that I have it figured out... can't use it because of visibility problem.  One step forward.  2 steps back.

I completely agree with the points raised by PROH  in reply to:  Rankleeminardi   I am also having some real issues with visibility/opacity animations in 3DS Max 2018.

I realize that I can animate the opacity of an object via it's material, but I might want to animate an object's visibility on a per object basis and if I have other objects that use the same material then this will involve a lot more work and complication to my workflow. 

I attached some sample work files where I tried animating the object's visibility, along with another example where I just animated the opacity of the object's material. I also included some sample renders.

Opacity animation done at the material level looks good in Arnold (after checking the Legacy 3DS Max Map support to get the Falloff map to work - I don't know why this checkbox isn't checked by default). 

Unfortunately, both the opacity and visibility animations look terrible in both Scanline and VRay. As the outer sphere fades away, instead of the inner sphere becoming visible within, the outer sphere fades to black until it's "invisible", then the inner sphere pops into place. This looks totally unnatural. 

Is there any work being done to fix this?! I am working on an animation with a lot of visibility/opacity fades of several layers of objects and I need to find a way for this to work.

I could set up multiple render passes with different objects visible and create the visibility fades in post but this would be ridiculous, a lot more work and it wouldn't look as natural in the end.
