I have some bucket errors. I do not know what is causing these.

Njeneb , this is a nice scene! I like it  :)

I tried your TGD but i have only the free TG2. And not the objects too. So i can not compare.
Edit : It looks very different in the old program (without the objects) with no bucket errors Henry.

Beside some kind of bug i wonder if it is a memory problem?
Try a render without these objects or-and with very low poly and textured ones.

Thanks Kadri.
I used localized clouds, so it would be quite different. I used Walli's pines and Dandelo's Maples.

I was thinking about the bucket errors last night at work. I'm 99% sure the problem is with the GI settings.

I did a render without the GI surface details box checked. It is a GI difficulty. Does/can anyone explain when and how to use the render detail region? I have it set at detail in crop now. I remember Matt or Jo explaining this, but I can't find the thread.

Hi Henry,

don't switch on GI Surface Details. AFAIK this renders subpixel level GI detail, and i have yet to come across a situation where this is required. I have recently rendered a (quite normal) scene that took 4 hours on 800x500 resolution, and I wondered why it took so long. I then discovered that I had GI surface details checked by accident.
I've had it unchecked, rendered again and the same image was done in 20 minutes.

As for the "ray detail region" setting: there is more to explain about it but I don#t have the time right now. You should find a good explanation here on the forums though. Generally for a full render just use the default setting "detail in crop region".

Regards,
Frank

Thanks Frank. 8)  I kind of figured the GI may be unnecessary when using Raytrace atmosphere.

I am still amazed how much faster 2.2 is! :)

I'm glad I saw this thread - (not meaning to hijack, but...)

This morning I was 10 hours into a render about half way done and saw this.  Sure enough, GI surface details box was checked.  Killed the render, unchecked, and started over and after 2 hours am at about the same place.  So for my experience, that single button push slows things down at least by a factor of 5.  I'd sooner bump up quality a couple of notches - I had no idea that this button push was so expensive.

He, he, try that one an old P4. :-X  I am thinking about getting the animation package. I can render some smaller anims without much difficulty. Plus having the ability to have nice cloud animations for logo work would be awesome.
