Render elements

[diegovfx]

Hello,

I am doing some tests with the vray standalone, using a scene file I have exported through the vrscene.
Can someone briefly explain how to see the list of elements and where they write to?
Do you need to render to exr in order for it to spit out the different outputs?

Thanks,
Diego

You can find a list of vray's predefined outputs in the pixelbuffer.h header in the sdk.

If you're rendering to exr or vrimg format, the channels can be included in the main image if you have img_rawFile set to 1 under the SettingsOuput options in the scene file.
Otherwise they should be saved as separate images in the same directory as your main image, with the channel name appended.

Hi rodeo,

Thanks for your reply.
I am using vrimage, but cannot find the setting you mention under the Settings in the vray globals.
Where can I find the SettingsOuput?

Thanks

Inside Maya, the list of render elements is shown in the Render Elements tab in the Render Globals. In the .vrscene files, they are exported as plugins of type "RenderChannelXXXXX" (e.g. RenderChannelColor, RenderChannelNormals, RenderChannelZDepth etc).

Best regards,
Vlado

Hi Vlado,

This I understand, but how do I actually see these individual passes?
Say I would like to see the GI pass of just the reflection pass?
If I am rendering to vrimage does it put these in a folder or something?

Thanks

There should be a SettingsOutput section in the .vrscene file.
But it looks like the img_rawFile setting only affects exr output, I think rendering to vrimg will always embed the channels. In that case you can extract the passes with the vrimg2exr utility.

I see, ok I will try this vrimg2exr

Thanks
