3D PBR environmental ground texture. A set of two 2048x2048 textures. Spring, summer and autumn will show the normal texture. This texture will show textured snow on the base texture in the Winter if the local altitude is above the set snow line. To adjust the snow line go into Surveyor and click 'edit environment' and then click the 'environment' tab. Now set the 'snow line' altitude to whatever you want it to be. Setting it to 0.0 meters will show ice with some snow wherever this ground texture is located on your layout.
