3ds 2009 64-bit, Windows XP64, Daylight System
Hi...
I'm taking this class and the instructor has us modelling with extruded splines - which is great.
However, when I try to use photons, I get very obvious light leaks between the splines.
Here's my work flow:
01) put the daylight system in the scene
02) put the camera in a room with big windows
03) turn FG off and GI on, 2 photons, sampling radius of 10mm
This shows me where the photons are hitting
04) I turn the sampling radius up to 100mm
The photons now have what I call a 'Flower Pattern'
05) If the Flower Patterns do not overlap 'enough', I turn the sampling radius up to 250mm
06) I then increase the number of photons from 2 to 100
07) At this point, I usually have a basic lit scene
08) I turn on FG on low settings to even the splotchiness out
09) adjust the FG parameters until it looks good
However, I have used Editable Polys up til now and never got a light leak.
If I did, I just turned down the sampling radius from 500mm to 250mm or 100mm until it stopped sampling from the 'back side' of the wall where the light leak was coming from.
The splines were drawn out and extruded. On paper, measurement-wise, there are no gaps (at least none that I can see).
But they are separate objects - the upper walls, the courtyard walls, the floor, etc. Should they all be attached and then verts welded?
