Using a depthmap as mask
on Nov 9, 2018 at 7:26:50 pm

Hello,

With a 3D plugin (Trapcode MIR) I created a low.poly landscape. Now I would like to add a glow-effect but not evenly applied to a complete adjustment layer. It should be controlled by a depth-map. The depthmap itself has pixelvalues between black and white so that elements which are more in front are more white and elements in the back are more black. Now I would like to do something like this.
Add an adjustment layer with glow and use the depthmap as mask (black = more transparent). Is this possible?

Thanks a lot (and sorry for my bad English)

Greetings from Germany ☺
M.

Can't you use the depth matte as a luma matte for that adjustment layer?

Sure, that's possible. You can use the depth map as a track matte [link] on your adjustment layer.

Alternately, you could use a Compound Blur effect with the depth map and an Add or Screen blend mode.
