This document goes over how to export cubemaps out of Photoshop using the NVIDIA Texture Tools plug-in.

Exporting Cubemaps (Photoshop)

Once you have a series of images laid out in Photoshop and ready to use as a cubemap, then you are ready for export. In this example, we will use the NVIDIA Texture Tools plug-in for Photoshop CS6. If you have not yet installed this plug-in, you can get it here.

  1. First, make sure your textures for the cubemap are lined up in a single document, and that they are all the same size. This size should also be a power of 2. Be sure that the frames are rotated as described here.

  2. Under the File menu, choose Save As.

  4. In the NVIDIA dds Format window, choose 8.8.8.8 ARGB 32 bpp | unsigned from the combobox at the top. Set the combobox underneath to Cube Map. Set MIP Map Generation group to No MIP maps.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
