Unable to render displacement (water) in larger areas

[jeri]

Hi guys,

Just wanted to ask around if any of you are having the same trouble with 'trying' to render larger area of displacement? For instance water / grass / rocks that sort of thing. With trying out the new beta version I can not help buy getting crash after crash when rendering a pool scene that I am working on. When I 'un-check' the displacement (0.5) then rendering in no problem at all. Does anybody have some advice on how to get the best / lightest settings when it comes to rendering displacement?

Many thanx!

Can you show us displacement-parameters , or to send us the scene if possible ?
Make sure that View Dependent is turned ON , and decrease Max Subdivs value to something lower like 4 , 8 or 16.
What about RAM consumption - how much RAM does Vray use during the rendering, and how much does you machine have installed ?

my suggestion is to save your GI maps (irradiance and LC) by rendering without the final pass, and displacement disabled. Then you can save and then load the maps "from file" and do your final render with the displacement turned back on.
