Shadows and lighting

Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

How can i get shadows to show up? They wont show.

Also, i know maya automaticaly puts in default lighting. How can I keep the defaults, and add my own. If I add a light, it stops using defaults.

You have to turn on either Depth Map Shadows or Raytrace Shadows in your lights.

If you use Raytrace Shadows, make sure you turn on the Raytracing in the Render Globals.

I'm not sure about using the default lighting in addition to your own. I've never had a situation where I WANTED to use the default lighting. :p

The default lighting gets wierd as you spin your camera around, so I wouldn't keep em for quality rendering purposes.

ok, but still. I want to keep default lighting, but when i add a spot light, it takes off defaults. I cant figure out how to get good lighting. So i need defaults.

never mind on the defaults. When i turned on ray trace shadowing, I get little grainy black dots for shodows. At highest quality...

may want to adjust your raytracing options in the light and/or in the Render Globals.

no i was doing a full render. I got it to work. Once i changed it to depth map, that helped a little. Then i found out I had the Anti-Aliasing on highest quality, but on preview mode.

Once i changed it to production mode, it turned out much better.
