Deep EXR - Edging issues when rendering deep data as new AOV or layer

Good day,

 

I'm having some issues with unexpected edging only when rendering a layer separately as DeepEXR or also when I create a new RGBA AOV set to DeepEXR and then use the DeepRecolor node in Nuke.

 

If I render the entire layer and all the AOV as a DeepEXR, then I get the expected behavior and don't get edging issues.

 

Entire Layer + all AOV when set to DeepEXR.

Correct

EXR layer for the RGB and a new layer or even a RGBA AOV as DeepEXR.

Incorrect

Nuke setup.

Does anyone know why this would be happening? The Deep data should be exactly the same.

Of course there is a big down-side when rendering the entire layer and all the AOV as Deep and I'd like to avoid that.

 

Hoping to simply have a RGBA AOV as Deep.

All the best,

Andrew

Sorry, I'm a bit confused about "layer". Is that a USD layer? Or something like a Maya render layer?

Hi there Stephen,

 

Yes, in this case I'm referring to a "Render Layer"

Somehow using the "DeepRecolor" workflow to add the Deep info into Nuke is still yielding in the edging issues.

I have read the Arnold docs here:
https://docs.arnoldrenderer.com/display/A5AFHUG/Deep+OpenEXR

 

Noted that a DeepRecolor method was used here too.

 

Will try a simpler test scene, but I'm using all pretty much vanilla "Arnold ROP" and nodes in Nuke.
Just appears like there is some difference between directly doing a DeepMerge on the DeepEXR VS doing the DeepRecolor way. Very strange.
