Just getting bored, almost finished the GI pre-pass.....to crash or not to crash? Voting is open now :P
[attachimg=#]
It's hard to see what is going to really happen. The GI pass computes the rough terrain. Let it render a while and see.
If you don't post and browse while you render it will finish ;D
Kadri.
Ghehe, I'm very curious too. In about 1,5 hour I'll be back home and we'll see :)
10 minutes after posting this the RAM-usage reached 3.47GB...I think I never went so far before.
I have reached 3.8 Gig and then it craps out. If you checked Preallocate subdivide cache you might be OK? Curious to see what happens here.

I think that depends on how much memory he has installed. I run 8 gig so I can render use photoshop and browse at the same time. ;)
It crashed after 15 and some hours...
I took the screenshot after 6,5 hours.
Funny was that the render hardly proceeded in those next 8 hours.
Probably thread after thread failed.
Memory usage at the crash was: 3.7GB RAM and 4.0GB VM size
I have 8GB RAM.
In some way nice to see when TG2 freaks out :)
Guess I'll render this again in 2 instances, expect it to work then.
Cheers,
Martin
hahahahaha
sorry ;)
Sorry :)
Do you use high quality textures in this render Martin ?
I didn't do a search here but i know from lightwave that by using only 256 color images you can sometimes sidestep such ram conditions .
The image impact with low color isn't most of the times so noticeable . Just in case for the others to know ;)
Cheers.

Besides masks from WM2 I never use masks :)
The reason this took so much because the setup is quite displacement-heavy but mainly because I'm experimenting a bit with lighting and slightly higher GI settings (GI @ 3/4/4).
I don't know if it possible to do such a sidestep with colors like in lightwave, but I'm also not sure if it really is desirable?

I don't know the state in TG2 but i tried it in Lighwave many times and it doesn't look bad as you think...Try it...
But when you are to much near the textures in the image of course there can be problems . So it depends :)
Kadri.
Just started the new render in two instances.
This time @ 2100x1200 (was 1680x960), det. 1, AA8, GI 3/4/4 with pre-pass and surface details (the latter for the fine foliage).
I often render @ GI 2/4/8 with pre-pass only and no surface details, which gives very nice results.
I'm not really convinced I really need these higher settings now but I just want to see the difference for myself.

Ok I'll try it in post. Perhaps a way of getting these type of image to compress more easily.

I use it in render .

Crash. Oh wait, are we looking at tgd.exe or iexplorer :P :P duh iexplorer will crash ;)
Internet Explorer? IMO more like Internet Exploder. It takes half an hour to load Google Home! >:(
Then use Mozilla or Chrome.
ie can't process javascript at all, which is why its so slow. and sites nowadays rely heavily on it.
my personal choice is chrome, but firefox and safari are great to have too. (i dislike apples though, so i dont use safari).
Ok, back to topic:
It crashed again, even after splitting it over 2 instances and thus enabling the scene to have access to approx. 2x times more RAM.
Which makes me wonder: why?
Which makes me wonder even more: why the excessive increase in RAM-usage over increasing resolution? It seems disproportionate?

i've been experiencing a lot of crashes these last days...
I did get rid of some crashes by lowering the value of first sampling level (just to the right of RT) from 1/4 to 1/16, but as you use only a few trees i don't know if it could help.
I have not had this happen since I reset the Large awareness program RAM size. I use 32 bit Vista.
Are you accounting for increased memory usage from increased resolution properly? If you double resolution, you *quadrouple* memory requirements for the image buffers. If you increase AA at the same time, it further increases memory needs.

Yes that's what I mean. I'm not entirely sure, but as far as I know many other renderers do not exhibit this behaviour/requirements when only increasing resolution. Ok, there's some increasing demand, but not in a similar fashion as TG2. I might be mistaken of course. Just thinking out loud.
TG2 keeps the entire image in RAM currently. Many other apps may only keep portions, or may keep the image on disk and write to it periodically. There are certainly more sophisticated ways to handle this in terms of memory use.
