So I've been spending some time analyzing mhaze's columnar, and have created a new shader set to apply a similar effect. It's not exact to how mhaze set his up but it uses the same principles of perlin columns detailed by voronoi as it's base. I than added some spice, and challenged myself on some strata like effect using the same voronoi and it's settings already in place (so it scales with the whole function setup).
I also redid the rock textures from scratch with the same lime leaching in mind. I think I may change the strata sedimentation colours though so they don't clash with the dust/dirt on surface tops.
PS If you know any free veggie models that might look good on this for a population test let me know! All I really got is grasses and big trees.
