Oliver Posted September 3, 2006 Share Posted September 3, 2006 Hi! I wonder something, probably quite stupid for the most of u, but i have to ask anyway. I´ve made an indoor design, without windows, so theres no light coming in, and i want to make the scene as light as possible. So, does it work having a skylight on a closed scene, without openings or windows? or do i have to fake global illumination? Cause i have some lights, spot lights, but thats not enough. And i want a very clear illumination, do u understand? Anyway, my question was: is it possible to have a skylight on an indoor scene? cause is not working for me, so better ask the one who knows! Thanks for your time! Oliver Link to comment Share on other sites More sharing options...
Brian Smith Posted September 3, 2006 Share Posted September 3, 2006 Skylight only provides ambient light. So if that's the only light in your scene, everything will look flat and without definition and depth. I would never recommend skylight alone for interiors. You can accomplish decent results with just a few simple omni's, good results with radiosity, or great results with an advanced render engine, ie. vray, mental ray, or brazil. Not sure what you mean by a 'clear' rendering. You will need to be more specific if this didn't answer your question. Link to comment Share on other sites More sharing options...
Oliver Posted September 3, 2006 Author Share Posted September 3, 2006 Hi and thank u for your reply. I know only skylight doesnt work, im trying with radiosity and getting better results, as trying with mental ray, im looking for a very illuminated scene (thats what i ment with clear;) ). Im still not good with mental ray for indoor illumination, im getting strange shadows and it takes time to render, so i will try something else... again, thanks for your reply!

Ky Lane Posted September 4, 2006 Share Posted September 4, 2006 A new technique I read up on and have been trying is set up direct lights with shadows turned off from all 6 axis directions, make the all instance copies so you can simply play with the intensity of 1....and also dont assume that having them setup at 0, 90, 180 degrees is best, move them around arbitrarily, and youll see different results...

Daylight Posted September 4, 2006 Share Posted September 4, 2006 @ Ky Lane sounds like a skydome! That will be the same effect like the sykylight. I would´t take that for indoor renderings. @ Oliver if you need quick rendertimes I would take fakeosity like smoke studio do. But that give you not the best results like mentaly ray or v-ray do! mfg jens Link to comment Share on other sites More sharing options...
Oliver Posted September 4, 2006 Author Share Posted September 4, 2006 Thank you! I will try that too, for the moment im playing with radiosity and some other lights, but i will definitely try that one... Thanks a lot for the reply! Oliver Link to comment Share on other sites More sharing options...
Ky Lane Posted September 4, 2006 Share Posted September 4, 2006 @ Ky Lane sounds like a skydome! That will be the same effect like the sykylight. I would´t take that for indoor renderings. Unfortunately, the render I had to do was an indoor AND outdoor render (huge apartment with alot of glass looking out over large outdoor area)...so I had the direct light rig setup only to illuminate the interior...seemed to work really well.

Brian Smith Posted September 4, 2006 Share Posted September 4, 2006 That's definitely a worthwhile technique. Before doing GI I would setup a free direct light in the bottom viewport facing perfectly upward. It would cast light on the bottom side of objects which usually don't get illuminated very well without GI. Link to comment Share on other sites More sharing options...
jackb602 Posted September 4, 2006 Share Posted September 4, 2006 You could just use an ambient occlusion pass as a starting point. Jack Link to comment Share on other sites More sharing options...
