Light passes opacity After Effects problem in linear

[Yan]

Hi!

I'm quite new to multipass render and linear workflow.

I have a scene with 3 lights that I rendered separately in open exr 32 bit, float buffer, linear, gamma 1.0.
I then opened the layers in after effects comp that is set to 32 bit float, srgb color space, linear mode and put the layers in add blending mode.

The problem appears when I want to animate the opacity of one layer/light from 100% to 0%. Everything works fine until the animation reaches 2-3% opacity, then it drops out very quickly like it dissapears an this is not smooth at all.

I know this is more after effects related, but maybe I am not exporting something ok.

Thank you!
