Generating Weightmaps for UE4

Development Asset Creation
1

Hello everyone, I’m trying to create a landscape for my project:
I have a terrain made in World Machine2, made by a friend of mine, I imported in UE4 the heighmap and the splatmap, but I met some problems that I hope to solve following this advice: https://answers.unrealengine.com/questions/47304/landscape-splat-vs-paint-can-we-bring-em-together.html

How can I extract each of the channels? I’m sorry but I don’t know WM, I have no idea how to do that

Here’s the project:

And then, one of the problems I mentioned before is the following:

It seems that the splat map he gave to me has not the blue channel… is that possible? Is it something that I can fix following the guide that i linked before?

You can find pretty good examples of how to use splatmaps withing the examples directory under WM Documents.

Although imo, you are better off not using splatmaps, and instead using individual maps for each layer, and using them on landscape import instead of using the splatmas directly in your material. You can’t edit splatmaps via painting in UE4. Whereas if you do selections that you then use a height output, set to raw 8bit, you can.

Check the guide in my signature.

Hope this helps!
