denoiser interrupts command line render

[ignuf]

hi,
I've been using a .bat file to render out a number of maya files , in each maya file the vray denoiser has been applied in the render elements

each render is set to render out one specific frame ( as these are currently test renders)

however for some reason the command line render would pause or halt right after the denoiser is utilized.. and does not continue on to render out the next maya scene.

As an experiment , I switched off the denoiser element in each file and the command line render would complete rendering out all maya scenes


contents of .bat file :-
render -r vray -x 1280 -y 720 -s 110 -e 110 "D:\projects_current_trboDrv\optician2020_Project\ scenes\lens_set_A_054_lens_2video_v01.mb"
render -r vray -x 1280 -y 720 -s 110 -e 110 "D:\projects_current_trboDrv\optician2020_Project\ scenes\lens_set_A_054_lens_3video.mb"
render -r vray -x 1280 -y 720 -s 110 -e 110 "D:\projects_current_trboDrv\optician2020_Project\ scenes\lens_set_A_054_lens_4video.mb"
render -r vray -x 1280 -y 720 -s 110 -e 110 "D:\projects_current_trboDrv\optician2020_Project\ scenes\lens_set_A_054_lens_5video.mb"

currently trying to setup the render elements in Maya for using the Denoiser Tool afterwards and struggling to find some of the suggested rendering Elements described in the help documents

• Defocus amount (named defocusAmount)
• World positions (named worldPositions or wpp)
• World normals with bump mapping (named worldNormals)
• Diffuse filter (named diffuseFilter or VRayDiffuseFilter)

please could someone advise on how to create / set them up ?

kind regards

Point taken, it's a bug and I've already forwarded it to our developers.
As for your second question - some of the render elements like defocusAmount you cannot create separately, they are created by the denoiser itself. Some though - you can (like the diffuse filter). For some like world positions, you'll need the samplerInfo render element in 3.6 or use a samplerInfo node as a texture in extraTex in 3.5.
However, if you set the denoiser mode to "only generate render elements" - it will add all those render elements for you, except it won't perform any denoising. The purpose is to have the render elements ready for denoising with the standalone denoiser tool. And (I've just tested this) it will not interrupt the command-line render, so you can use that as a workaround until we fix the bug.

This was the same issue as I was having https://forums.chaosgroup.com/forum/...er-batch-files

I too was using denoiser with command line render.

This is already fixed for the stable nightly builds. You can grab a build from there if you have access. The fix will also be included in the next patch release.
