[Oli4D]

Hello everybody
I'm currently learning studio lighting with some studio lighting books (for real photography), but of course doing that in Maxwell with Cinema4D.
So far, Maxwell really nicely behaves like it should , but I have a problem:
In Studios, you often need spot lights where you can adjust the cone angle, have a possibility to adjust the gradient of the light (smooth transition into dark or hard edge of the spot)...
I need to be able to do that with Maxwell to.
But how? Any ideas?

Basically I need 'physically correct' modelled spot lights, light they would be in the real world, with the ability to change the cone angle, etc.

Has anyone built such lights in Cinema4D he might want to share with the community?
Or are there somewhere tutorials how to build a correct, realistic spot?

Has anyone such lights he might want to share with the community?
Thanks a lot,
Oliver
