massive vray slow down when animated visibilty ?

[martin walker]

Im creating a "build up" animation of a petrol station canopy. Each bit of steel work has animated visibitly Object Properties > Rendering Control > Visibility.

 

Im not using GI, just straight forward render from vray with a "light dome" of a dozen or so omnis.

 

Im have MASSIVE slow down of render times. I did this about 6 years using scanline, and it spat frames out at around 30 seconds...so I'd expect the same again now, but even faster.

 

Anybody any clues ?

 

thanks in advance

This is a known issue.

 

Animate the material instead has been the usual workaround.
