HDRI strange flickering on some objects

[Zeilveen]

This is strange stuff, Im working on an animation of a small village and Im doing the surrounding area as simple boxes. Im importing DWG files straight into MAX and extruding the houses. Some houses are flickering (about 1 outa 10). The shadows are seem to go on and off every so frames. Its just for these 1 out of 10 houses but its so anoying. I've checked the geometry of the houses and that seems fine. The material of the houses is just plain Vray with nothing except a red colour.

 

So far I've spend 8 hrs trying to clear this problem and my deadline is getting too close now.

 

info:

VRAY 1.4704 with MAx8

Light setup = HDRI in enviroment slot and reflect slot

One Omni light set to OFF

 

Things I've tried:

- Other HDRI image = no help

- Changed almost every render setting = no help

- Changed all HDRI settings (angular/mirrored ball/ etc) no help

- High AA / High GI / High Subdiv = no help

- Only thing that helps is rendering without HDRI and use Vray Light Dome

but thats just not what I want, but will do for the time being.

 

 

 

Many thanks for any good advice and would like to get to the bottom of this, I must be doing something wrong and hope someone comes up with this tip.

 

Cheers

Solved the problem. Turned out that my scene was too far out of the 0,0,0 coordinates system causing Vray to flip and do funny things..

Ronald-

 

That is interesting... I know that was a problem in MAX for a long time, but I thought it had gone away...good to know and thanks for sharing.
