Hi, Iīm a Max newbie. Or at least Iīm not that experienced with rendering and stuff... I made some outdoor scenes and use the Light Tracer for these shots, just to mimik the outdoor feeling with ambient light that darkens inwards corners and so on.
I read somewhere (and have realized myself) that this Light Tracer isnīt made for indoor environments and so forth tried to use the Radiosity-feature...with quite awful results. Of course īcause I canīt handle it. Yet.
Anyone who knows good tuts on this Radiosity-stuff, īcause the help-file provided didnīt really get what I wanted anyway, and neither got me to understand it quite...

Thanx...

What du you meen with awful results with radiosity? Wierd spots and distorted shadows?

If so, try raising the iterations of all objects (in advanced lightning dialogue) and quality of the radiation from 85% to 95% ->.

Good luck!

Weird artefacts inwards the corners in the pic that has an outdoor lightsource... Tried to play around with the parameters, but with no luck...

The links doesnīt work for me etiher :(

Is the outdoor light logarithmic? Mixing different light types can make intersecting shadows flip out!

Just learn how to fake it with diffuse only soft shadow casting lights....

and a few non shadowing casting for color bleed....

I've put three links up on my site that point to pages about faking global illumination by hand.

the artifacts near te ceiling and floor in de window.jpg can be caused by 2 things :

1. try to model your intersecting surfaces as clean as possible
overlapping surfaces can cause light leaks
cut the meshes so there can be no floors sticking outside and recieve ouside light

or try with a smaller meshing size for the walls, ceiling and floors to avoid subdivided meshing sticking outside


2. using the advanced raytrace and area shadows could give leeks of lights in the corners in my experience
try fideling around with the settings of the shadows if that doesn't work using normal raytrace is the only thing left to do

good luck:bounce:

I think I've had simillar problems, try putting an outer wall on your room to stop leaks.
