Hey everyone -- I’m dealing with the same animation flicker problem that seems to plague the Vray world at large. The consensus seems to be that this effect is symptomatic of a cracked install … my company owns several licenses of Vray, so I don’t know how that could be the case. Anyway, I wanted to post an example of what’s happening to me so you guys can decide if this is in fact a symptom of a crack before I go and reinstall Vray and authorize it again through Chaos. The scene is lit with a tripple ring of standard lights (for fakeosity) using shadow maps and by one key sunlight using Vray shadows. GI is completely off. Sorry the example is so short -- had to make sure the building identification wasn’t visible since our client information is confidential. Just put it on repeat and you’ll see the flickering immediately. [http://www.shaundon.com/example.avi](http://www.shaundon.com/example.avi) Thanks for your advice! Shaun ---

I think you had better get hold of chaos about this one … it does look like an Autho problem
