Step 3: Open the project. Press "More", then "Browse...", then find where you unzipped it, go into the W3D Texture Baker folder, then open "W3DTextureBaker.uproject".

Step 4: Once the project is open, go into the TextureAssets folder, and create a new material (right click in the Content Browser, then select material).

Step 8GIMP: Open the HDR image, then set precision to 8 bits per pixel. Use perceptual gamma (sRGB).

Step 9: It's ready now to become a DDS file that W3D can use.
