Cubemap caching.

[FullStack0verfl0w]

What can't you do?

When building cubemaps for envmap probes the game slows down significantly. This becomes an issue if a map has a lot of probes. The engine will build cubemaps every time a map loads, decreasing performance for a minute or two.

How would you like it to work?

When Update Strategy is set to On Enabled, cache previously built cubemaps on disk and use it later instead of rebuilding all over again. Also allow rebuild cubemaps on demand either through a method in Envmap Probe component or through a console command.

What have you tried?

Rendering cubemaps by hand and assigning them to each probe is not an option.
