How can I render a region or a crop in vray cloud for max?

Hi alessio_parolin ,

I'm sorry for the slow reply. [EDIT]: Unfortunately if you set a region from the VFB in V-Ray for 3ds Max and then submit the scene to Chaos Cloud, the region won't be exported and submitted to Chaos Cloud. Hence we'll render the whole scene, not just the region. There's a logged issue to add support for Region Render from V-Ray for 3ds Max in Chaos Cloud and V-Ray Standalone. It's internal ID is VMAX-6431. Meanwhile there's a workaround which you can use to set a region in your scene in order to render it in Chaos Cloud. You need to export manually a .vrscene file (using the .vrscene exporter from the context menu in 3ds Max). Then open the .vrscene file in a text editor.

The render region uses these parameters in the .vrscene file located in the settingsOutput plugin:
r_left=pixelvalue;
r_top=pixelvalue;
r_width=pixelvalue;
r_height=pixelvalue;

Find the settingsOutput plugin and add these parameters to it. To find the correct values more easily in pixels, create a region in the VFB by dragging. Then print screen the VFB. Use the screenshot as a reference as the pixels of the region will be displayed in the VFB. Enter the values for the parameters in the settingsOutput plugin corresponding to the numbers from the VFB. Then save the file and submit it to Chaos Cloud by double-clicking the .vrscene file.

You can use this workaround until we implement the Region Render support from V-Ray for 3ds Max (VMAX-6431). Please first test it with a quick render (with small resolution and/or low quality settings), so you can be sure that everything is fine before submitting your final scene.

A note here - you'll see a warning on the Chaos Cloud client app Submit page that you're going to render just a region from your scene. We added the warning as a precaution for people who, for example, have set it while testing with IPR (Interactive Production Rendering) locally. Sometimes people forgot to turn it off when submitting to Chaos Cloud. But if you want to render the region, ignore the warning and continue.

Bests,
Vladie

Sorry to bring up an old thread. Region rendering is still not working in when submitting. I cannot find those renderion parameters in the settingsOutput. This is what I have below:

SettingsOutput output_settings {
img_width=2560;
img_height=1440;
img_pixelAspect=1;
img_file_needFrameNumber=1;
img_clearMode=0;
anim_start=880;
anim_end=885;
frame_start=880;
frames_per_second=1;
frames=List(
List(880, 1030)
);
}


Is there a way around this? I really don't want to have to spend so many credits for such a small region.
