Skybox / Horizon Question for track builders

[Caribstu]

I'm having problems with the skybox. Recently built a 'winter' version of one of my tracks (video link attached) and i've been trying to alter the horizon to snow covered hills.

I've tried changing the BKAA-BKAD textures in 3DsimEd3 but it causes it to crash.
I've tried adding the new snow horizon textures to the map.gtr but that causes GTR2 to crash

Any info on how to do this? Is there a particular way the horizon BKAA-BKAD .dds much be saved that i'm not doing?
I think the overall feel of the winter circuit would be vastly improved if the horizon was snowcovered.

All help appreciated.

As far as I know: BKAA, BKAB, BKAC, etc. are not legal material names for a GTR2 (or GTL) skybox. I typically use eight segments; they are named BKA, BKB, BKC, BKD, BKE, BKF, BKG & BKH and they are assigned 1024x768 dds graphics with the same names.

Very cool to see a winter track in GTR2
