DR problem/ pre-calculated lighting howto

[hektorkata]

hi i'm new to this and i've been testing DR for the past week. this is a case out of my ordinary experience with DR for the past few days. in general i see that DR is working but not in this case.

What happens is i get the following 2 warnings when SU crashes and i never get to see any result (i'm trying to render 690x380). this happens at the very beginning of the process, before the render nodes are connected, even before that i guess. The scene freezes and sometimes only the MS VC++ error pups up, sometimes both errors appear:

Error #1. Visual C++ Runtime Library: "SketchUp has requested the
runtime to terminate it in an unusual way.
Error #2. MS Windows XP: Virtual Memory Minimum too low Windows has
increased your Page file...

here's the configuration (all WinXP 32-bit):
intel P4, 2.8 HT, 512MB, desktop PC
intel core duo, 1.8, 512MB, mobile PC
intel core duo, 1.8, 1024MB, mobile PC (client)
(the SU file i'm working on is 60BM)

question:
1. this looks like insufficient master RAM to handle the scene, respectively insufficient RAM in general, doesn't it? if i put the max RAM (2GB) on the master would it help jump start the actual DR process?
2. what steps do i follow to save precalculated lighting and how do i apply it on a bigger res image?
3. crash happens with the gi_irmap_high.visopt. should i use another visopt/render options that require less resources and if so which one(s)?
4. what's the part that Visual C++ plays in this problem?


any advise?

Re: DR problem/ pre-calculated lighting howto

I'm not sure exactly whats happening, and chances are its not going to be something very obivous...in other words, we'll need your scene to track down the issue. I don't think it really has anything to do with RAM or your visopt. There may be a weird geometry situation or something else. Visual C++ is the programming language that programs are written in, so C++ is playing a huge role in things; errors or not.

As far as precalculating maps, all you really need to do is enable Don't Render Final Image, which is in Global Settings (this basically prevents you from actually rendering out the final image...ie vray will only render the maps). Then either render and save your light map, or set it up to autosave after the rendering is done. Then change the mode to From File and select your saved light map by clicking Browse. Then you should be good to go...and be sure to disable Don't Render Final Image.
