[@KevoStudio]

@@ActionVFXofficial Thanks you!!

[@aymenazouz9065]

hello ! where can i find the matt for the vfx ?

[@mikedftv]

Can you use this for an adjustment layer? I’ve tried but it still shows the white behind it. I’m trying to brighten the sky in an animation. I’ve got a seperate alpha matte for it.

[@ActionVFXofficial]

Yes! it should work with adjustment layer as well. Making sure that the matte layer is disabled when it is being used as an alpha/luma matte by the layer below it. Let me know if this works! -Danasa

[@mikedftv]
