Material transitions blending/diffusion/smear when working with voxel terrain?

Hi, I have seen a few topics on this matter however none of which give any clear answer if it is possible to control the transition between materials?

At the bottom I have two screenshots that does show that the engine does this already, but I cant seem to find any way to control this manually.

Some materials need some blending/smear/diffusion when transitioning between different materials to look and feel natural. While with others it is wanted to have a sharp transition, In my humble opinion I think that the current transition is perhaps a bit to sharp and would overall look and feel better if had it been a bit more gradual, but this is a matter of taste and highly dependent on use by use cases.

If we cant control this I would like to propose two different suggestions.

  • A: Giving each material a new property that defines blend/smear/diffusion ratio to neighboring materials of different type.
  • B: Seeing we can write voxel “material” and “occupancy” giving it a third property where we can control each voxel how much it should blend with its neighboring voxel, this I think would give us the perfect control of material blending/diffusion/transition and we could express transitions differently in different areas / use cases.

I would ask this in feature request but I cant post there so I will just stick it here and hope others see the benefit from this topic and pushes it up the chain of command.

Roblox has some pre determined basic blending, but sadly there is no fine tuned control of it. This is a feature I’ve wanted for a long time and the only way around it that I’m aware of is dotting bits of the terrain manually to mix them a bit.

I was really hoping we’d hear something about material blending at RDC 2022, but all we got was better water that we’ll probably see in a year.

Feature request is locked to regular still. How does one get regular? you dont
