Thanks,

That's a long running project ;)

Start playing with the FG settings, the values are too low.

Also, there seems to be some modeling issues, resulting in 'light leakage'.

I was just wondering why there's a strip of sunlight coming from the gap on the right of the door, but no sunlight coming through the windows.

I was wondering myself after you mentioned it,

especially the part about the windows.

Indeed!

although not a fulltime long running project.

I adjusted some (a random bunch)stuff. Its too dark but I think the light is falling right. I have better info:

Render settings look ok, should be looking much better even with that relatively low fg setting. That bright blotchy frame around the image and the halos look especially strange. It must be in the materials or light or geometry setup, hard to tell. Maybe you could post a polygon reduced version of the scene. Which material are you using?

a5' · Post by **a5'** » 20 Aug 2010, 13:28

Well the halos around the sconces over the doors actually have some point lights in them so that's the explanation for those halos. The blotchiness around the frames I don't know and the halo on the ceiling also I don't know.

architectural material--

I can't reduce the scene enough to post it but I uploaded it elsewhere. ReviewAug20_2010.zip
couple questions,

do you have to post the scn 'table of contents' to make the scene readable?

where do you define 'Max Resident' setting?

Thanks,

a5

rray · Post by **rray** » 20 Aug 2010, 14:12

my 7zip can't open the rar in the folder, the smart.scn looks much nicer already however (well on the bottom-half-fg preview, my machine is so slow)

no scntoc needed, I think the max resident is no setting, mr is just logging how much RAM it needed for the BSP.

One thing was I was just wondering, why did you use a falloff node on the portal lights? From what I understood they don't have any falloff since the (theroetical) light souce in infinitely far away (environment).

Must run, will have another look when I'm back home

a5' · Post by **a5'** » 20 Aug 2010, 14:29

Yeah, I have so many of these scenes I don't know which is the best although I think I started from scratch at one point but didn't finish the moldings.

I'll check the Smart.scn

compressed folder should open with windows 'Compressed (ziped) Folders'

The reason I say that (about the max resident) is because I have more RAM than its using. I remember in 5.0 there was a BSP control area. I think I did notice when I got 2010 that I didn't see one..

I didn't think I set the falloff in the portal lights but it was because I thought they automatically fell off due to FG. I'll check that parameter.

Thanks alot,

a5

rray · Post by **rray** » 20 Aug 2010, 19:01

This is what I got off smart.scn, only thing I did was I removed the falloff and increased fg settings to maximum (2000,40) and diffuse bounces to 5.

Still some blotchiness coming in from the side into the view, strange thing. But ok otherwise. What I think it could be you had in your last picture was a corrupt fgmap file.

That makes a lot of sense, I've been working on the scene today and gotten somewhere but its taking forever to render.

I'll try that out.

Thanks,

Well, I spent most of the day trying to get the scene I was working on to work and then some more time with the smart scn after I changed some things it started to take a while to render again.

what did you mean by 'removed the falloff', it looks to me like the FG falloff is off?

anyway Thanks for your help, I'm going to continue with that scene. Much faster.

smrt.jpg

I suspect though that there is another solution for those smokey blotchy things, aside from turning up the FG values.

-----

I'm sorry I forgot how much information they had given me on xsibase a while back about this same scene.

http://www.xsibase.com/netview_forum/index.php?board=16;action=display;threadid=40903

I think, according to Lupin, it was possibly a smoothing error. I have to get back into that thread.

sorry for possibly wasting your time

thanks,
