Optical Flares
on Aug 31, 2010 at 11:39:21 am

Hello,

I have two compositions. Each containing quite a few instances of optical flare plugin from Video Copilot.
Now, i want to make a transition of the two comps, in a new composition - But, when the two comps (with multiple OF plugins) overlap, they make a terrible noisy image!

The other solution is to export each composition with an alpha channel, aaand I've also tried that.

When I make the two compositions overlap, they also create a very disturbing image... it doesn't look exactly like the other problem at all, but very bad too.

How can I make these two compositions cointaining Optical Flare plugins, overlap with transparency without faulty images??

Much appreciated!
Cheers,

Anders

How are you transitioning from one comp to the next?

Can you post a screenshot of the noisy output you're seeing?

Yes - http://lilkaer.dk/OF_error.png

What you see is essentially two splines generated by trapcode particular, that has lights tracked to the Emitter-light. When they overlap, the error occurs.

As mentioned above, if I export them as alpha channels and then try to overlap eachother, another bay error occurs.

Has one of the comps been repositioned (thus revealing an edge?)

Or have you tried disabling GPU rendering within the plugin?

No, the comps are exactly at center both of them.
And I've tried with and without GPU rendering....

Allright! The problem occurs when working in 32bit! 16 bit works fine :-)
