Correct way of using Z Depth in Redshift

Recommended Posts

I am trying to render out a simple wireframe with depth i.e. the wireframe object fades into the background. Ideally, I want to control the fading threshold in compositing software but I don't have Nuke which is what most tutorials out there are using.

Relatively new to render passes, wrote Z depth output into EXR but it is recorded in world units I believe so I find it hard controlling it.

I tried using a COP network but can't seem to make it work/don't know how to remap Z depth mask. Any advice on that? Attached file.

On a higher level, what is a good option to use for editing multilayer EXR sequences? I typically use Premiere for simple editing but there aren't many EXR tutorials for it? After Effects seems convoluted. Is Nuke my only good option?

Not really sure what is the problem. Your file seem ok to me.
I just adjust a bit min and max depth.
Effectively these are in world unit, which is quite convenient IMHO.

I also prefere don't use Camera near/far. I Just use it to find the corect min and max values.
By the way are you in bucket mode to tweak parameters ? (Z AOV don't work in progressive mode).

Da Vinci resolve who has a free edition can also do the trick

Thanks! That makes a lot of sense :)

I did some digging and there are both free versions of Nuke and Da Vinci Resolve + Fusion. I wonder which one is better to learn / has less limitations.
