I'm starting to mess around a bit with bagginbills environment sphere. I read through the instructions and understand the basics. But there's some things that are confusing me. I'll number them for better readability:

  1. I easily get this render on the bottom:

But i notice there's no shadow on the ground. In his other renders on this page:

https://sites.google.com/site/bagginsbill/free-stuff/environment-sphere/environment-sphere-demo-renders

there's shadows on the ground. How to i use the sphere to get shadows on the ground? I added one infinite light for the sun, and i could get shadows on the body, but not the ground.

  1. When i turned the shadow strength from 1 to 2 with GC enabled, the shadows came out blue. I just wanted to darken them. Any ideas what's going on here, and is there a way to darken the shadows without that weird effect?

  2. Say i want to use a particular scene or some scene props, with a ground plane and maybe a few walls or rocks. How do i set up the sphere so it uses the props, and includes a sky as the picture for a prop based outdoor scene with a sky? Would i use one of the EvoDome or EvoHemisphere that's included in the prop folder for this?

  3. For the HDR or LDR image to come out right, it says to decrease the camera focal length from 75mm to about 15-30mm, otherwise it will be too blurry. Is there a way around this, or do i always need to decrease the camera to those settings?

  4. Where can i find some good sky pictures for the skydome?

  5. How would i apply indirect light to an indoor scene? Would the IDL bounce rays off the insides of the scene, or would i still need to use the dome?

I'm liking indirect lighting a lot. With one yellowish infinite light, it makes an outdoor scene look really realistic, much better than using regular lights. Any other tips would be helpful. I understand basic lighting to a decent level, but i'm still new to using bagginbill's sphere and how it works.
