Problem with export

[brainspoon]

Hi,

When exporting a scene to a vray scene via batch it produces code that is causes an error in the standalone renderer.

rgn_left=-1.#IND;
rgn_width=160;
rgn_top=-1.#IND;
rgn_height=120;
bmp_width=160;
bmp_height=120;
r_left=0;
r_width=160;
r_top=0;
r_height=120;

Those lines with -1.#IND that are written to the SettingsOutput vraySettingsOutput block produce an "expected a ";" after property definition" during rendering with standalone.

I am using Maya 2010 on Win 7 64bit and the vray demo.

Hm, thanks for the pointer, will take a look at it; I think this may be fixed for newer builds already.

Best regards,

Have you selected a camera for batch rendering. This can be done from Render Settings -> VRay Common -> Image File output -> Batch render camera (at the very bottom) ? The official release has this default to "None" which may cause this problem. Newer builds have it default to the persp camera.

Yes the camera was set to None. Is it possible to specify it from batch with the -cam flag?

In general, how are scenes with multiple renderable cameras handled if only one could be specified in the render globals.
I could do several batch renderings or exports with different -cam flags in each, but that would overwrite the images each time, because the camera name is not attached to the image name as maya woud do it normally.

You can use the "%c" flag in the "File name prefix" field, it will be substituted with the camera name. And yes the only way to render from multiple cameras is to export/batch render multiple times, once for each camera.

I guess you are talking about the -cam flag of the vrend command ? In batch render mode V-Ray will always use the camera specified with "vraySettings.batchCamera".

I was talking about the -cam flag of the maya batch renderer
Render.exe" -r vray -s 1 -e 10 -rl "cylinder" -cam camera1 -proj "W:/RenderPal/Maya/" -exportFileName "W:/RenderPal/Maya/scenes/export" -noRender"W:/RenderPal/Maya/scenes/vray.mb"

Render.exe" -r vray -s 1 -e 5 -cam "cameraShape1" -proj "W:/RenderPal/Maya/" "W:/RenderPal/Maya/scenes/vray.mb"

It would be great if the V-Ray plugin would handle it the same way like Maya. If there are multiple renderable cameras, append the camera name to the image name automatically.
Now I would have to script checks that force the user to do this.

Ok, I'll write this down as a feature request.
