Standalone DR prepass bug?

[vlado]

Will check it out; in the meantime, does it work if you modify the image size/region directly in the .vrscene file before rendering?

Best regards,

Over the weekend we had rendered the image without -region -crop - imgWidth -imgHeight flags:

C:\Programme\Autodesk\Maya2011\vray\bin\vray -sceneFile="xxx.vrscene" -display=1 -distributed=1 -portNumber=20207 -renderhost="xxx.xxx.x.117" -renderhost="xxx.xxx.x.161" -renderhost="xxx.xxx.x.113" -renderhost="xxx.xxx.x.104" -autoClose=1

And as you can see on the image we get the same error! This morning we rendered the image within Maya and the image is fine!

This is a nightmare for us! We need to render over 30 HighRes images in the next weeks! We can't render them individually in Maya!


Please help!
Thanks
Lars

We had set the image size in Maya (Renderview) and then wrote out the vrscene file. Is this the same?

You can always render them through the Maya "render.exe" command; in any case we are trying to reproduce the issue here, but it does not seem to occur (or at least not that often), which makes debugging somewhat hard.

We are so used to the vrscene road, so I totally forget the render.exe way.

How can we use the flag that we use for the standalone, like display or renderhost? Need to do some research...

Is this true that render via vrscene and standalone is more memory effective and faster (a little bit)?

Hope you find the bug soon. If we can help you in any way, drope a note.

For -display=1 you must enable VFB in Render Settings. You can add there the render hosts too.
It seems that we've catched another bug... Is this the same scene that you've send us? And are you using a new build? Can you reproduce the bug each time with the same render settings/command line? Maybe try to render using different hosts. We must catch some pattern there (or lack of it ).

[seq]

Thanks Ivaylo.

Yes it is the same scene. And yes we use the build from 14th december.

The bug appears every time we render the scene, but the pattern are different each time.

We can try to render the same vrscene with different hosts over night if this would help.

[seq]

No luck: The attached image was rendered overnight via Render.exe and what do we get, the same bugs as via standalone. This drives me crazy! If we only could find out why this is happening and why only we have this problem!?

Yesterday we tried to render some tests via standalone and we found that old bug (which I thought was fixed already), that when you did not specify the region and crop, then the standalone renders outside of the image. Also we specify the image size in RenderView, in the standalone flag and we also changed it inside the vrscene file. The region=none flag was no help.

When the Render.exe way also is not working, what can we do anymore?

[ivaylo.ivanov]

So, if you render in Maya with GUI with DR, it's ok, but in batch mode and with standalone you get these artifacts?

[seq]

Maya with GUI is always fine. Render via batchfile with Render.exe -r vray and render via batchfile with vrscene produce these artifacts.

Here are the results from the test renderings we had done over x-mas:

upload.sequenz.com/vray/seq101228_all.jpg

All images are nearly the same scene (just some AA and IR map settings changed).

Result: Wether we render via Render.exe or standalone the bug appears everytime. Sometimes more obviously like in the one at the top right corner and sometimes it is hard to see. Render with fewer hosts didn't help either. Only when we render without DR and standalone (image still render at this moment) the bug disappears.

In the VRMayaSpawner.log only appears the following alert:

Crazy thing is if we us the same scene and turn the camera so that we see the opposite wall, we get a clean image (rendering with standalone and DR).

Why?
