It seems master lights will not project an image correctly if the spotlight angle is set to anything but the 45˚ , the default.  The image stays proportionally the same size and the light around it either gets smaller or larger.  I’ve attached an image of the behavior.  The top three light projections are unslaved lights, and you can see even changing the cone size the image sticks to the outer cone (default).  The bottom three are slaved to a master.  At 45˚ they appear correctly, but small as shown the image is cropped.

I’ve posted the project file here http://www.blackboxdesign.com/EIAS/masterlight.zip

Is there a way to get this to work?  I’m trying to make a whole bunch of down lights look more realistic, and I need the flexibility to adjust their light cone angle.

Thanks,
Yon

Hi Yon,

You’re right, that looks broken!
What’s really interesting is that the problem is progressive. An outer cone value of 45 (as you say, is fine). 40 is still good, 38 is okay, 35 not so good, 30 looks broken....

Being progressive, it might not be somewhere between bug and feature
I’ll ask about it on the beta server tomorrow.
Sorry I can’t be more help,
Ian

Ian,
Thanks for looking into it.  I’ve found a quick work around, which is to expand the projected image’s canvas size, adding blank space around the image, until it fits with-in the light aperture.  That’s easier than breaking the slave connection having to reassign all of the light properties. 

Curiously, if you disable the slave light’s info > master> projection box, and set it to project independently, it still behaves like the faulty slave.  So simply setting the light to slave breaks some code.
