I need to be able to create a gobo projection effect so if theres a way i can do this with corona lights in absence of an actual projection slot on the corona light, that would be great.
This was your initial request, wasn't it?
It would be better if you were specific and detailed enough for what you wanted to achieve.
I have provided a way to create the colored volumetric effect from the video above, which you somewhat liked, and it seemed that was what you were going for.
The sent scene uses Photometric lights, which have option for projection map option.
Weren't you aware of it?
So, you can use standard lights, which have Projection map option, with Corona, with CoronaShadows.
You can get somewhat close results with IES and real volumetric material, but remember that there will be issue with render times.
See the image attached, is this what you are looking for?
If yes, use the Projection map option advanced effects menu of Standard lights.
