Animated proxies never used to do this, something changed? Max 2022? I can no longer do viewport previews of animations with animated cproxys, they just flicker as a box. This was very useful before to check how fast a tree was moving and generally see the whole animation of a scene before rendering it. I'm specifically referring to - Tools > Preview Grab Viewport > Create Preview animation.
Any help is greatly appreciated, thanks in advance.
Cheers.
