File Name Prefix <Layer> Not Working

[Stirk]

The File Name Prefix <Layer> does not append the render layer name to the file name. As such, if multiple layers are rendered, then each layer is overwritten by next layer. If I do not add <Layer>, then nothing saves at all.

My current convention: <Version>/T38_<Layer>_<Version>
(The layer name is PlaneFG)

Expected file output: v020/T38_PlaneFG_v020.0001.exr
Actual file output: v020/T38__v020.0001

The only way that I have got this to work is by creating a layer override for the File Name Prefix and manually adding the name of the layer. However, I still must include <Layer>, otherwise nothing will save. Like this:
<Version>/T38_<Version>_<Layer>PlaneFG

I am using Maya 2017 (update 3) with the new Render Setup and V-ray 3.52 EDU.

This seems to be working fine at our end. Are you using 3.52.03?
Can you attach one scene just in case ?

[Stirk]

Absolutely. I've attached the scene. Yes, I am using 3.52.03. I should also mention that I am batch rendering from the Windows context menu (right-click > Render).

Thank you!

The issue is reproducible with your file, but we have to test a little bit more to see where exactly is the problem.

Actually I have a question.
Have you created those layers in the older Maya version or the setup is done completely on Maya 2017 and new render layer management ?

[Stirk]

The setup was done in Maya 2017's new render layer setup. I did import the plane geometry and animation from a Maya 2016 version, although I deleted all of the original render layers before exporting it. I don't think there is a way to convert the old render layers to the new ones, which is why I did so.

[tashko.zashev]

It's considered as a bug and our developers will work to fix it. I will post here when we have any progress.

[Stirk]

Okay. Thanks for taking a look at it. Interestingly, the master layer, if set to render, does render with "masterLayer" in the prefix. Anyway, I deleted the render layers, re-exported the geometry, camera, and animations from this scene, and imported it into a new scene. So far the <Layer> prefix is working correctly with the new scene.

[tashko.zashev]

Yes, I noticed that too, furthermore it seems to be a problem with our renderer only. However, we'll try to fix it.

[Stirk]

A very similar problem is occurring with the new scene. One of the render layers is now being labeled incorrectly. The PlaneBG layer is being labeled as PlaneBG_smoke, which is a different render layer. The output saves this way too. I've attached this file in case that it is useful.

[tashko.zashev]

Thanks. I'll forward it to our dev team.

Thank you for the very detailed bug report! We have found the cause of the problem and we are currently testing a fix. We'll notify you when there is something.

[Stirk]

You're welcome. Thank you for looking into it!

[Mihail.Djurev]

The problem is fixed and the fix will be available in our next release.

[Stirk]

Excellent! I really appreciate it.
