[Answered] How do you use an HDR Probe in Zbrush4R5?

I downloaded one, and now I’m not entirely sure how to use it in the Lights menu.

Material -> Modifiers -> at the bottom over the “Channel discriptors” button

You need to use a landscape proportioned panorama - a spherical or cross image will not work. The HDRShop program will convert between formats (if it’s still available).

  1. Import the image into the Texture palette.
  2. Click the image thumbnail in the Light>Background sub-palette and select the image from the pop-up.
