Please, please make the visibility track of objects capable of being animated in all renderers.
I am currently using 3DS Max 2018. This worked fine in previous versions of 3DS Max.
Also, please ensure that animation of a material's opacity map works properly in all renderers. Since the visibility track animation isn't working right I tried animating the opacity maps at the material level, but either way I get bad results.
i attached some sample files and renders as a reference.
