dude, surface shader is awesome. May I ask what did you use?
thank you man! I sculpted the planet in Zbrush and then baked normal maps on the low poly. Nothing new. After that I painted insied Substance painter mask, where I want grass and rock textures to be on the surface. These masks I used then in Shader Graph in Unity and lerped them with textures.
Btw. your planet shader looks sick too man :D Real terraforming is going on there!
