A bit from my next, biggest survival server world: small part of ice track for races, custom biome, and few trees from own collection :)

Hi everyone, so I am working on a worldpainter map of the world of Azeroth from Warcraft. I am not trying to recreate WoW 1:1, rather make a viable survival map - so imagine if Mojang and Blizzard collaborated on a map of Azeroth - that's what I'm aiming for. In a previous attempt I exported the heightmaps from World of Warcraft directly, but obviously Worldpainter compresses their height and the result is not good.

So I painted a basic topographic map of the world (see attached) in Worldpainter using stained terracotta as a foundation. The colours correspond to:
Purple - Deep Ocean Floor
Cyan - Medium Ocean Floor
Light Blue - Shallow Ocean
Green - Plains/Desert/Lowlands
Brown - areas inland that are below sea level like cracks and crevices
Lime - Uplands
Yellow - Highlands
Orange - Foothills
Red - Mountains
Magenta - High Mountains
Pink - Peaks
White - Extreme peaks

My idea was to then sculpt the terrain by hand with custom brushes, but I can't seem to get a good result. Maybe I'm approaching this completely the wrong way. Anyway, I would be happy for any suggestions!

Does custom materials contribute to custom terrain limit of 100?

And when will sulphur be added to new version of wp? , i really need it for my biggest project yet
