What is the principle of snow spreading on terrain and objects? Is it possible to somehow disable the creation of snow only on the terrain but leave the creation on objects? And I also have a proposal - to make it procedural like dynamic vegetation, that is, so that you can control it more clearly. At least so that you can map noise, gradients, masks, etc.
I don’t know about the terrain but for mesh objects I believe you can just disable the option for accepting decals and that may work.
It’d be nice to have a lot of options like that exposed in script canvas if they’re not already, btw. It may already be there but I did notice there’s very few nodes for manipulating mesh entity and material options.
