sometimes when I do a light cache at 2500 subdv. it freezes up towards the end. I noticed n the task mgr the four buket are going 100% and then they drop off and that is when the cache does to go further.
I have a 2.6 quad core chip with 4gb of Ram on xp64.
the preocess takes up only 1.61 of the RAM
When I lower the subdv. it works out ok. Also dif views of the model do better than others.
any sugestions
Which V-Ray version is that? It would be best if you can send me problematic scene to vlado@chaosgroup.com so that I can take a look.
Best regards,

Why don’t you try to tweak the other parameters? In many case the default value, 750 or less work very well , but it needs more tweaking from the other render options.
I’m not sure about trying to catch the good ratio in increasing the lightcache subdiv value.
But just my opinion.
