Pre cashe textures?

Is there a option to call to preload the texture prior to sceen contruction for the landscapes? if so what is the option call? thanks in advance

No option to do that.

will there be in the future? or is there a way to tell find out when the textures are finshed loading for load screen removal or progress bar movment?

textures are loaded on paging demand... so at start, no preloading...
using delegates you can get the texture load event per page.
