Optical Flares - Ae in 32bit float leads to wrapping values

Great plugin - thx again for such a great tool.

Just having an issue here in AE CS4 comping in 32bit float. When a solid layer containing OF is set to 'screen', the values from OF seem to be wrapping around 1.0 and leading to inverted looking overexposure. Imagine an atomic blast where the sky gets so bright it goes beyond white and turns green for a moment. That's what I'm getting inside the flares hotspots when comped over other 32bit float elements - also happens when 2 flares overlap.

If we set the solid to 'add' instead of 'screen' it works as expected, however is too blown out for our needs. We need to use screen.

If we set the comp the 16bit, it removes the problem however we need to comp in 32bit float.

Let us know if there is something we've overlooked. Thx again!

I am having the same problem with 32bit, is there a way round it?

I'm having the same problem here. I was wondering if anyone had come across a solution for this?

Cheers,

Same here (see attached image)

I'm getting this problem regardless of the blending mode (flare on the left (black solid in screen mode)), plus it does it when I apply the effect directly to the EXR layer (flare on the right). I'ts obviously only doing this in 32 bit mode, and then only over bright areas. >-||

I'm not seeing a workaround. Anyone else found a solution/had info back from VC?

Cheers
