Pixelated Shadowz


(Bapsis) #1

Hey all,

Was wondering if anyone knew why my shadows are so pixelated (osa is on 16), and how i might go about fixing it.

Increas the shadow buffer (BufSi).
Additionally the Bias could be increased.
Make the ClipSta value as high as possible and the ClipEnd as low as posibble for a complete illumination of your scene.

“Samples” also affect this. For best (and slowest) results, put it up to 16.

–edit—
it can be found in the “light” section

I think that having Over Sampling on 16 is too high, to much time and it makes the scene look fakey.

OK, here is my typical “Spot” lamp set up, FYI:

BufSi: 1536
Samples: 12
Bias: 0.01
Soft: 12
SpotSi: 65-80
SpotBl: 0.85-1.0

Everything else, just leave as is. From there, just adjust you ClipSta and ClipEnd, and Distance to suit your scene.

This should get rid of those jaggies on your shadows.

Now, to take this a step further, you can put in a few “Shadow Only” spots, and make some of them “Layer Only” as well. This can make your scene come more to life. Just play around with them until you get something you like.

A good way to set the ClipSta and ClipEnd properties is to view the scene through the spotlight. With the light selected, press Ctrl-0. Then raise the clip End until you can see your entire sceen, then raise the clipSta until the scene starts disappearing and then back it off a little. You’ll need to select your camera and press Ctrl-0 again to make it the active viewpoint.
