  • How do you make a layer that is a LUMA matte not transparent to layers beneath it?

    Ok, Ill try and explain this as best as I can…basically I have 2 layers one of which is a luma matte to the other. Now I want to fade in another layer that is beneath these two layers. But as soon as the other layer appears, even if it is at a low opacity is immediately visible in all white areas of the luma matte. I tried to precompose the two layers but this still made no difference. I want to fade out the luma layer while bringing in the other layer but the fade is really bad because the other layer doesnt really fade in…oh dear….please help!

    Thanks

    Dan

    My English is terrible, so let me see if I understand: You have achieved to make a layer transparent through a luma. And you want to fade in a new layer BUT the transparent parts of the luma make them visible beneath the first layer.

    My first choice: Can you put that new layer ABOVE the other ones and just change it’s transparecy?

    Second choice: If it has to be below, you could use the same luma layer for the layer that fades in. And you could animate the brightness of the luma layer so that the transparent parts become opaque while the layer is fading.

    I hope you understand what I mean, if the first layer is transparent, make transparency the same in the second one.
