What is the correlation between "No Weight-Blend" layers and the "Alpha Blend" blend type?

Doesn’t have to be. But usually the very first layer of the blend - and you also need to fill the landscape with it and paint other stuff on top.
which to me is a red flag. You pay the cost of 2 layers on everything if you look at the shader cost. I prefer artifacts to that

Make a near empty layer with a neutral grass. Only 1 texture. And use that as the base with no blend so it’s the cheapest cost possible without using a solid color.

To be honest, I have seen 0 artifacts/black spots so far, I only seen that everyone strongly advises to do this procedure, so I was being cautious. I also would prefer a few artifacts to add another layer. It takes already a lot of time to compile it so it might just not be worth it.
