KS9 / Gpu rendering and render layers doesnt work

[Andrew_G]

Hi,

I just noticed that Render Layers function doesnt work while rendering on GPU. I checked both with layers in PSD and as a PNG files, and those layers are completely broken and useless. There are some artifacts, black lines and so on. This function is completely broken... When the same file is rendered on CPU everything is fine.

Just letting you know about this, as for the moment I will try to work it around. But this is one of the most important function for me, so it would be nice if it start working again. But in general in my opinion all functions with passes, render layers, alphas and so on need thorough update. When I will find some time, I`ll try to explain what I mean:)

Best regards,|
Andrew

Thanks for sharing. I was able to reproduce on my end.

It would be very interesting to hear your thoughts about the render passes etc.

I would suggest to add (at least):
- "Vector Motion Pass" for creating motion blur in post
- A "UV Pass" to have the possibility to change textures in post. Maybe with the new UV feature in v9.1?

If you like to do something ground breaking, consider implementing Cryptomatte (Clown Pass on steroids)
But this may be an overkill for KS.

Please, add a check box: "[ ] Store passes in folders" for animation, so each pass is stored in a separate folder. Otherwise you need to do this: https://youtu.be/9BcrkguPYX8 all the time.

One more thing:
Please, include the material bump into the normal pass in Product Mode!!! It is included in the interior mode, but who likes to render an animation twice to get the right pass. But maybe it's already solved in KS9, didn't check the latest release

+1 on the vector motion pass and cryptomatte. Not an overkill at all
I see more and more people using KeyShot for professional animation work that would benefit from these features.

Oh man...Cryptomatte would be immensely helpful (as would folders for render passes, ha).

As Eugen mentioned in his last post and showed in a short clip (https://youtu.be/9BcrkguPYX8) collecting the passes may help. So I wrote a simple script.
This script can be used via a batch file that should be stored in the frames folder. It will create a subfolder if the pass file is available and move all files that fits the naming.type.

Just copy the following rows and save them as a .bat file.


if exist .\*_ao.exr md .\ao | move *_ao.exr .\ao
if exist .\*_caustics.exr md .\caustics | move *_caustics.exr .\caustics
if exist .\*_depth.exr md .\depth | move *_depth.exr .\depth
if exist .\*_diffuse.exr md .\diffuse | move *_diffuse.exr .\diffuse
if exist .\*_gi.exr md .\gi | move *_gi.exr .\gi
if exist .\*_label.exr md .\label | move *_label.exr .\label
if exist .\*_lighting.exr md .\lighting | move *_lighting.exr .\lighting
if exist .\*_normals.exr md .\normals | move *_normals.exr .\normals
if exist .\*_raw.exr md .\raw | move *_raw.exr .\raw
if exist .\*_reflection.exr md .\reflection | move *_reflection.exr .\reflection
if exist .\*_refraction.exr md .\refraction | move *_refraction.exr .\refraction
if exist .\*_shadow.exr md .\shadow | move *_shadow.exr .\shadow
if exist .\*_clown.png md .\clown | move *_clown.png .\clown

This may save some seconds of work?!


Cheers

Seconds?  ... Hours, Days, Years 

Thank you Marco!!! This will help as a workaround.

Note:
The script is written for EXR files and needs to be adjusted for other file extensions.

Ahhhh, man!! This is great, thank you for sharing this .

Here's an update to customize slightly easily. And I guess it makes all the coders laugh out there.
