Hey people. Ive been working on a Chopper in Wings 3D and posting my progress over there. Im rendering it in Bryce and im having trouble with the shadows, THERE ARE NONE! Im using a light dome (see image)i currently have 73 radial lights all set to an intensity of 1, cast shadows is on, shadow ambience is at 0, and the soft shadow setting is at 57 (a random number really). Im guessing im getting no shadows because all the lights are canceling them out. Is that whats going on? If so/not can someone let me know how I can fix the problem.

the link is to a sample image used to render using the same set up.

Do you have soft shadows or any other shadow-dimishing feature on? Is the brightness of your monitor set at an appropriate level? MoonGoat (Second question was a joke)

Do you have global shadows "ON" in the Skylab? Without this set to on, you will have no other shadows...

What I would do is...

Check that shadows (and soft shadows) is turned on in the sky lab. Turn off shadows for all the lights. Then turn shadows (yes, make them soft) for one or two of the lights off to the side.

It'll render alot faster and that many soft shadows being cast are probably washing each other out.

Is the picture linked to, a bryce render? If it is, make sure that the ground is accepting shadows. Or you might have shadows covering the entire ground.

I guess there's something even MORE important going on here. The whole point of using light domes is to not NEED softshadows, as the light dome creates the softest shadows as it's main purpose. If you had one or five lights, then maybe soft shadows would be important, but it's not. And it's just gonna drive your render times way, way up. Forget about them and try it, see how it looks!

How much is the ambience of the floor?

I've just woken up, still feeling a bit groggy.......but to me the attached image appears to have shadows :^|

Looks to me like either: Cast shadows is off on the bike while self shadows is on. OR more probably... The ambience is too high on the ground texture.

I'm with LSD - turn SS off or set the value really low.


lordstormdragon ( ) posted Thu, 27 January 2005 at 7:50 AM

Aye, not to be a jerk about it, but the only reason TO use a light dome is because you don't feel like using SS. Or vice versa. Sometimes SS drives render times into oblivion, and without premium settings SS isn't much better than a light dome can get... Although light domes hit objects from multiple angles, they are generally a soft-shadows technique or a "global illumination" technique. You honestly don't need 73 of them really, but it's your render! Try it all, learn as much as you can...

Also remember that when using a light dome you have to control the brightness using the color setting of the light. That might be part of it too.

I fixed the problem! Thanks to all of you for your help. What I did to fix it: Turn off the 'cast shadow' setting on ALL the lights, except 1. Then on that one light, I increased the intensity to 10. Heres what I got with that setting.
