View Full Version : Radiosity+daylight not lighting foliage

I'm using 3ds Max 8. The foliage in the scene is standard that comes with the package. I'm rendering using radiosity and logarithmic exposure control with some tweaked settings. Anyway, even with the brightness bumped up for some reason I cannot get the foliage to be lit, it remains very dark. However in the exposure control, the preview image shows the foliage how it should be lit. Also, the daylight light/skylight are IES, I've tried standard, but still nothing. Any ideas? Thanks.

Hey Harryhood,

First question, why are you using radiosity on an outdoor
scene? Radiosity is specifically designed for indoor lighting
simulation. If you must use the scanline renderer light tracer
will give you much better outdoor lighting.

you can use anything you want to light your out door scene. I have done outdoor scenes with Radiosity before.

To me it looks like it's working correctly. you are looking at the dark side of the tree because of the angle and direction of the sun. maybe i'm wrong??? if you rotate to the other side of the trees is it bright?

If I am wrong then maybe try converting the trees to a emesh...save a new file first.

When I render from a view where the sun is hitting the trees I still get unsaturated colors and black. It doesn't make sense though, because in the exposure control the preview thumbnail shows it like it should be, trees colorful and everything, but when I render I get black. I'll try making them meshes but it's my scene is already so heavy because of the foliage it's running real slow.

I've tried adding other lights to illuminate just the trees (omni's). I re-calculated the radiosity solution but the trees are still just black/grey, and not very illuminated. Has anyone else had trouble illuminating the foliage that comes with max?
