Redshift Renders Particles Instead of Liquid Mesh in Picture Viewer or Redshift RenderView

If your liquid simulation looks correct and appears meshed in the Cinema 4D viewport, but renders as particles in the Picture Viewer or Redshift RenderView, it’s likely due to the Export settings of your Liquid Mesh object.

To ensure your liquid renders as a smooth mesh, follow these steps:

1. Select your Liquid Mesh object.
2. Go to the Export tab in the attribute manager of the Liquid Mesh
3. Turn ON Geometry. (You may also want to turn on Normal for smoother results.)
   
4. Re-render your scene in the Picture Viewer or Redshift RenderView, and this should result in a proper liquid mesh as expected.
