Hello

So I know I am responding like 3 years after you posted this but I found your post cause I was looking for an answer to the same problem. I found it. Firstly the tutorial you spoke of from which you got the formula was most likely Andrew Kramers – https://youtu.be/22N_fXrBAWQ

I too tried this but it did not work for my purposes so I rewrote it as follows..
value+[effect(“Displacement Map”)(“Max Horizontal Displacement”),-[effect(“Displacement Map”)(“Max Vertical Displacement”)]]

Hope this helps someone out there.

Hey

Just figured it out – silly me :/

‘convert to linear light’ must be set to off

how could one type an expression on a precomp layer which effects each layer inside the comp accordingly ?

i am trying to apply a fill based on depth expression to all layers inside a precomp from outside the comp.

at the momment I am applying the following to each layer inside the precomp :

c=thisComp.layer(“Camera”); // choose the active camera //
cp=c.toWorld([0,0,0]); // camera’s position in world space //
p=thisLayer.toWorld(thisLayer.anchorPoint); // this layers position in world space //
d=length(cp,p); // calculate distance from camera to layer //
far=10000; // far distance for black value //
f=linear(d,0,far,1,0); // calculate fill colour from distance //
[f,f,f,1]

if i could do this from the outside then i would not need a seperate depth comp and the depth would update according to what i do in the ‘beauty’ comp.

hi…the problem im having with this is that you cannot correctly apply the LUT generated from ARRI website in a linearized comp. it has to be 32 bit with no color space.

this means you cannot properly comp multipass CG layers etc.

how are you guys setting up your project color space ?

i really need help so if you could please detail the full process it would be a great help. right now i am following this…
