Splatmap communicates with UV's or vertices?

Do I understand correct?

Splatmap uses alpha channels to show or hide an array of textures.

Splatmap tells where on terrain’s vertices the array textures will be visible. So then resolution of texture blending is dependent on amount of vertices?

Probably it is possible to apply via UV data in order to use an optimized mesh but still get good resolution? If so, what must our UV’s look like? Stay in 0-1 space, be able to scale up down for tiling?

And a mesh can hold multiple UV channels, correct? What benefit can we gain from that?

No, quad have only 4 or 6 vertices and can be used to project textures of any resolution regardless of that fact.

Splatmap like blending techniques usually use one of two: vertex color or texel color, but not both, to select texture influence it’s depend on concrete case of using.

what’s this mean vertex color or texel color?

Vertex color means the area around a vertex recieves color? Texel refers to using a UV map? So just a choice between vertex painting or UV?

Vertex color means color values that come from the vertex data.

Thanks guys. I’m at a poitn where the answers to my questions are usually full of words/concepts that I don’t know… so I got lots of reading to do!
