I created a custom template for Snow Landscape generation with Gaea.
The snow process is quite straightforward, but I wanted to add more variations to the albedo, and more details for the rocks area with a thin layer of snow on top of the rocks. etc. The actual shader in the blender is not 100% efficient. But Since those assets are intended to have a custom landscape shader. I'm not too concerned. And should look more detailed once I setup those files in Unreal Engine
Geometry vertex count is at 2k with Textures going up to 8k.
Nanite and Virtual texture will be my friend, once in Unreal!
