Hello all,
I'm looking at ways of using Luxology to create reasonably accurate film or cinema type image projections to study cinema wall and floor finishes. I'm using spot lights and transparent image slides, but it does not seem possible to create in-focus projections at realistic distances. I need to be able to calibrate light output in lumens or similar to check that my estimates are reasonable.
Alternatively, can anyone give suggestions on using glow materials or area lights to simulate rear-projection screens? Again, I would need some way of calibrating the simulated brightness.
If anyone has tried this before, or has any advice, please let me know.
Thanks
James
Like the man say, if you get the latest update you can apply image maps to spotlights. This is brilliant news.
So for your rectanglar spotlight, you just need to create a mask with a white rectangle inside a circular area that fits within the square image file. If that makes sense.
Basically, the spotlight stretches the square image file to fill the cirular spotlight so you need to fit your rectangular gobo within that circle.
Ooh, volumetric effects also respect the spotlight image map. Exciting stuff.
Just a note, this map doesn't seem hooked up to animation yet. Needless to say, animated projector maps are a pretty cool feature (would be even better if we could specify .avi's as textures but that doesn't seem to be on the agenda).
I've tried assigned the first of a numbered series of maps as the color map and that doesn't seem to work, also the map is not listed as a scriptable attribute in the 'Animate Source Lighting Settings' tool.
Hi Colin,
We plan to focus on improving the Animator going forward and hooking up all the new Luxology materials will be a priority.
