VrayLightMix Renderelements

Hello everyone!
I render my scenes and save all renderelements to different *.png files.
Is it possible to reimport them to VFB and adjust the lightmix then again?
Alternatively how would I mix them in Photoshop?
Thank you, Harald

HI it is not possible to adjust the LightMix once the renders are saved in png. You can save/load a pre-set and render again or you can also apply the changes to the scene lights.

If you save to a single file (vrimg or exr) then you will have the LightMix stored and editable.

Thank you Vladimir, it seems, exr will do the job for me.
