Encountered annother issue, while working with V1.17.
When the (standard) fish eye camera is active the manual point and click light placement doesn't work as desired. regardless of the value of manual placement distance, the light is always placed in the same way. there seems to be no possibility to adjust lights according to zoom factor.
in three point perspective it works, but especially in animation workflow, this is no alternative.

I found the problem. It happened when View / Close up (zoom) was quite big (e.g 1e-2). There was a bug in the code.
Until I release new version you can use following workaround for fish-eye projection. Use on all keyframes very low value of View / Close up (zoom) (e.g. 1e-15). This will not have any influence on camera position (in fish-eye mode it is ignored) but lights will be placed in proper position.

By the way in next version will be some kind of 3D pointer/cursor which will help to setup lights (it already done - see attached image). I'm also thinking about some visualization of camera path.

Thanks Buddhi, your workaround works perfectly. Indeed I never took care of the zoom factor in fish eye view, cause It has no effect there. I normally navigate with forward/backward and the windroses - especially in animation environment.
Looking forward to seeing the new features, you're working on!

I was just thinking the other day how cool it would be to have these two features.
Fantastic work, Buddhi. Thanks very much for your psychic abilities as well as your programming ones. smiley
