Cubemap not working + a bunch of errors

[D-Miurge]

I've got two problems.
1. The reflections on glass is still showing a default skybox (

) - how can I change it to a custom one? A cubemap is placed right next to the glass (on 64 height) and I used "buildcubemaps" command in game.
2. I have a bunch of random errors while running around the map -

. I could use some help as I seem clueless :/

When you build cubemaps you won't see the new ones straight away. You need to reload materials to see them.

There are a few commands you should type. Here's a guide.

Check out CompilePalX, which will handle your compile, pack custom content and build cubemaps for you.
