Hey guys,
Hmm that’s strange I can’t seem to reproduce this in my scene, but perhaps you can try going into the “terrain blended materials” folder and open the material instance you are applying to the terrain. Then try increasing the number for “Tessellation Density” and see if that fixes the issue? It must be more noticeable on the grass ground texture because of the more intense variation from the blades of grass being tessellated out from the landscape. Have you guys noticed this with any other tessellated terrain materials you yourself made or from the marketplace? I may just have to adjust the heightmap of the grass to not have so much variation in it so that it’s less noticeable.
As for the river material, you can change the max speed of the river by going into the “master_river_water” material and off to the left side of the material graph you will see the the “Panner” nodes lerping between a slower speed panner and faster speed panner. There should be about 3 of these lerps for the normals and 2 of these lerps for the foam at the top of the material graph. Just decrease the max speed of these panner nodes and it will set your water to whatever speed you want on the slopes. I hope that helps!
Perhaps I should add a node to set “Max water speed” to be exposed in the material instances? What do you guys think
