View Full Version : Ok, so it's not a V-Ray render.

The V-Ray thread kinda peaked my intrest in using fake radiosity on indoor architectural scenes. I use fake radiosity on most of the work I do but never thought it could be applied with decent results to fully inclosed indoor scenes. This is the results of my first experiment so far. I need to tweak the lighting a bit more to achieve the realisim I'm looking for. I'm working on the textures now but thought I would post it without the textures first. I would appreciate your thoughts on whats right and wrong with the lighting so far. Thanks!

Hello, I like your results so far (if that matters) but please don't take this wrong.
If you have the time and means, why would you try to fake it instead of using real GI?

heh heh...nice modelling as always bud.
i'd like to see some of the archvis guys n gurlz comment on this as they work with this sort of thing everyday they have a far better feel for it. for me personally..its feels very ambient lighting at the moment apart from the fact you have the window light on the floor..but you didn't make it easy for yourself with that raised roof section as it changes what you expect slightly.

Thanks flingster. I was going for that early morning kinda look. There are two windows on the walls that aren't in view casting light also but I can see I need to tweak it some more to darken the foreground a bit. Panchopantera, It's nothing more than render time. After I add more objects and texture this and using radiosity, it would take days on my puter to render. This took about 2 minutes to render and when finished and textured maybe a half hour. Also checking textures and bumps etc. as you build your scene using radiosity is a long drawn out pain in the....... Thanks!

The overall distribution is nice, but everything is looking quite floaty. I think you could take it up several levels by adding ambient occlusion to the walls, ceiling, and floor. Of course that might take render times into GI territory, but it's worth a shot.

Adam, I'm doing just that as I texture. If you look at the coffee table you can see I added ambient occlusion to it as a test for shadows. Yes it does bump up the render time but it's still alot faster than GI and I only use it selectively where it's needed. Thanks!

By the way Adam, here's a problem I'm trying to find a workaround for when using a lightdome and ambient occlusion together. If you look at the shadows around the objects on the table in this scene I did you can see they aren't correct for the lighting. The dominant lighting should be the light coming in thru the windows but it's actually the light from the lightdome above. I'm working on it though.

also don't forget you have the luxury of being able to use negative lights to darken areas you need to tweak maybe.

btw...like that last image has quite a bit of atmosphere though
