Help me understand Landscape material setup

jordank95

I have setup landscape mats in the past, but with newer versions of UE4, things have changed. I have my landscape setup like this, and its causing me nothing but issues. I cant seem to paint correctly at all. I have it set to "non-weight blended" and for some of the materials, it paints the terrain black. Sometimes I cant even get the textures to paint at all. All I want is a material setup where I can blend between 4 different materials with  tessellation. I was also getting issues where one out of the 4 materials was just painting black. So I changed all the textures to "Sampler Source: Shared Wrap" and now all the textures show, but I'm getting strange errors I noted above.

Whats wrong with my setup? Thanks for all the help guys, always a big life saver

This is a classic.......bug

Try to fill one of the layers instead of painting. Then it should work.

@Obscura thanks for the help! That fixed that issue. Now my other issue is I can't for the life of me figure out how to make use of my height maps and get some tessellation on the landscape. Here's my material setup. Nothing is working. Any idea?

Normally you don't import the height map in the material, although you probably could... but normally you import it through the "new landscape" menu.

Thanks! Though I'm trying to use my height maps from my landscape textures I created in Designer. The landscape itself is already sculpted out, I just need my landscape textures to have displacement derived from the height map that was created in Designer.

Here's my material setup to better understand how I have it setup. I just need my landscape material to have tessellation like how I created it in Substance Designer. I am not getting any tessellation at all, but if I increase the "displacement level" parameter as seen below, it just raises the whole entire landscape rather than tessellating it according to the height maps.

Ok, Im an idiot. I figured it out myself. I had the VectorLength node plugged in wrong. Had a V3 in with a V2 out rather than a V3 out.
