My landscape in world machine is 1024x1024, for the texture i generate 4 different ones with the same size(i use Costal overlay macro). Then with photoshop i merge all the 4 texture and i add some filters to obtain the texture i posted before. The landscape format is RAW16 while the textures are in RAW format. To increase the texture dimension i should increase the landscape size which i don’t really like. here’s some screens of world machine and PS.
