If you are doing much of this sort of work I would seriously suggest investing the time to learn Blender 3D - it will not cost you more than time and the sweat on your brow as it is completely free, (both without cost and Open Source), to get and to use for any purpose. It is cross platform but obviously needs a reasonable amount of storage and processing ...

(You can also get tilt scales on lower-end video-oriented pan/tilt heads, but you usually have ...

It's not trivial to calculate from scratch the amount of light required (as you have no idea how much is absorbed, reflected etc. and it will vary according to how the lights are positioned). What you can do, is find out what shutter speed your camera meter is suggesting currently and work it out from there. You'll want to aim for 1/2f where f is the focal ...
