Remote Rendering

It is possible to upload render jobs from home machines to process on the workstation machines at University.

Note this system is for V-RAY only. It can be from Rhino, Sketchup or 3D Studio but the renderer must be V-RAY.

To use the system you need to export a VRscene from your application and drop it into the “IN” folder of a OneDrive share. Once uploaded the scene file will be processed and returned as a PNG image in the “OUT” folder of that share for you to pick up.

To get access to this share you must first request access from:
DesignStudios@greenwich.ac.uk

You will then be emailed the OneDrive link to use for upload / download.

To avoid blocking the renderer with unnecessary jobs please check your scene is correct before submitting; e.g. by doing a small render or partial render on your own machine to check the output is what you want.

Points to Note:

  • This must be a VRAY render
  • Rendered files will be auto-deleted after 3 days – please copy your renders before they are purged
  • Don’t use simple short names for your vrscenes in case they overwrite or get overwritten by others.
  • While these renders are in the Out folder, all other render users can see them
  • Non-progressive / bucket rendering will be faster and more reliable
  • Please be sensible about render image sizes otherwise an all job size override will need to be implemented.

Custom Materials and Lights

If you have created your own materials, dome lights, etc. with non-standard bitmaps then these bitmaps will need to be uploaded too:

  • Upload the associated bitmaps to the OneDrive folder “3ds-Materials”
  • They must be fully uploaded BEFORE you upload the vrscene
  • These files WILL NOT be auto-deleted, so once they are uploaded then subsequent vrscene files will be able to use them too.
  • If materials or HDRI backgrounds are not showing correctly in your final renders then it is likely to be because of non-standard bitmaps.

Export from V-Rray Rhino / Sketchup Pro

Within Rhino or Sketchup ensure your viewport is showing the view of the model you want to render and that the V-Ray settings are as set as you need them.

Note: Switch OFF Interactive and Progressive to enable bucket rendering – this will run quicker on the render system.

The PNG file will be generated at the size specified in Render Output.

Create the V-Ray scene file by choosing V-Ray – V-Ray Rendering – Export VRScene…

This will export a file containing all the information needed for the render service to process it (try using a unique style file name to prevent it overwriting, or being overwritten by, other files on the share with the same name).

Once the file is generated then drag it to the IN folder of the _studentrenders OneDrive folder you will have been sent a link to. The file will then be uploaded to the render system for processing.

Note: You can keep adding other views / scene files to this folder; the system will queue them up and work through them all.

Once the render is complete a corresponding PNG file is written to the OUT folder and the original Vray scene file is deleted – when the original file disappears your file is ready.

3D Studio Max / V-Ray

You can export a standalone V-Ray scene file from 3DS but for it to render properly you need to use V-Ray or standard materials – the physical materials will not render correctly. Similarly non-V-Ray atmospheric effects like volume fog will not be recognised – please try to use the V-Ray native effects if possible.

Set your view in the main viewport and your render settings how you want them – including the output size for the image file

On the V-Ray tab select Image Sampler type as Bucket; this will render around 10 times quicker on this system

In the viewport right click and choose .vrscene exporter

If you are rendering an animation the click the Export Animation tick box. This will save each frame as a numbered PNG.

Select the name and path for your vrscene file and hit Export.

This will export a file containing all the information needed for the render service to process it (try using a unique style file name to prevent it overwriting, or being overwritten by, other files on the share with the same name).

Note: You can keep adding other views / scene files to this folder (give them different names); the system will queue them up and work through them.

Once the render is complete a corresponding PNG file is written to the OUT folder and the original Vray scene file is deleted – when the original file disappears your file is ready.
