Telemachus Posted January 17, 2005 Share Posted January 17, 2005 Hello all, I am having a bit of trouble with outdoor lighting. I've always used a series of about 6 Omni lights to light my houses, but the resulting lighting doesn't make the houses look *photorealistic* despite having good textures. I've tried the Sun system, but to no avail. The houses come out too grainy and I can never seem to position it correctly. (Maybe there is a good tutorial somewhere?) I've also tried Photometric lighting, but it seems to have no effect, even though all of the objects in the scene are included. (Weird.) Anyone have any tips for me? I don't use Radiosity at all (takes forever), but would like to get to the next step for lighting. Thanks! Link to comment Share on other sites More sharing options...
IC Posted January 17, 2005 Share Posted January 17, 2005 I think you have two options: 1 Use radiosity and learn how to optimize your settings, 2 Use 'fakeosity', normally using a dome or ring of lights. Search this site for both options and you'll get loads of help. Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted January 17, 2005 Share Posted January 17, 2005 does viz have light tracer? Link to comment Share on other sites More sharing options...
lambros Posted January 17, 2005 Share Posted January 17, 2005 I think that viz 2005 does not have light tracer. Link to comment Share on other sites More sharing options...
webwimp Posted January 19, 2005 Share Posted January 19, 2005 hi there, perhaps you may want to use the manual way of placing the sunlight. and this tutorial on external lighting is pretty similar to what you wanted to do. http://www.cgarchitect.com/resources/tutorials/smoke3d/tutorial8.asp good luck!

Bugga_Guy Posted January 20, 2005 Share Posted January 20, 2005 Neither Viz 4 or 2005 have light tracer. Download the E-light script by Ronnie Olsthoorn. Its a wonderful script for outdoor lighting. And best of all its easy to use. http://home.wanadoo.nl/r.j.o/skyraider/e-light.htm Link to comment Share on other sites More sharing options...
NEVIANS Cedric Architect Posted January 23, 2005 Share Posted January 23, 2005 sorry ... but actually ... Viz2005 have radiosity and MR render but lightracer is not present in .... Link to comment Share on other sites More sharing options...
LukeC Posted January 24, 2005 Share Posted January 24, 2005 Ive had some very good results with using a dome skylight and inserting a spotlight to simulate shadows from the sun. But that can be a bit costly on render times so that might not be your best bet if your concerned time. Also have a look at your exposure control and have a play with that.

Telemachus Posted January 24, 2005 Author Share Posted January 24, 2005 I want to say thanks to everyone. I went with Bugga Guy's light dome and the results are really great. The houses still look slightly "plasticy," but it's a distinct improvement on just using Omni lights. I will trying using an additional spotlight to see how that works. Thanks, Dave Link to comment Share on other sites More sharing options...
Bugga_Guy Posted January 25, 2005 Share Posted January 25, 2005 The trick is to add more lights (coloured omnis, usually what I use) on top of the ones provided in the light script. Its all tweeking and trial and error. Also be sure to insert bitmap images as well - kinda like HDRI. Link to comment Share on other sites More sharing options...
