Skydome Help - Understanding the different maps to build painterly Sky in Blender

Hello,

I was recently creating a painted skybox inside Blender and figured out how to bring it into Meta Horizon. However, I noticed the documentation button doesn’t lead anywhere, even though it appears active. I’m also based in Australia, so I don't have access to the AI tools.

I’m currently trying to figure out the three other map types through trial and error and would appreciate some clarification:

• Radiance Map (256x128): I’m guessing this is an equirectangular black-and-white texture used for lighting?

• Reflection Map (768x256): I assume this is similar to a Unity reflection probe, though I haven’t seen that resolution before.

• Fog Map (384x64): This is a stretch, but I’m guessing it’s a depth map based on the display map, though I’m not certain.

Any information you can provide to help break down these textures would be greatly appreciated.

If I can get everything working correctly with my Blender setup, I’m planning to create a tutorial to show how to make rendered/painted skydomes in Blender for Meta Horizon.

Thanks very much for your help!
