Ue4 - Terrain Mesh Normal Blending with Virtual Textures Guide!
Hey its my first post here. Hope this guide will help yall ! Couple of months ago when i started playing with Ue4 i was obsessed with terrain mesh blending. So i started searching but couldnt find any tutorial on how to do it. After some search time and experimenting i finally found a solution. It was already there but i… -
Re: Ue4 - Terrain Mesh Normal Blending with Virtual Textures Guide!
Nice job there! I have been fiddling around with terrain mesh blending long time ago (before virtual texturing was a thing in UE4) and yes, there is not much information about it online at all. There are some basic attempts, but nobody seems to have nailed it so far. To blend properly, we basically need the complete… -

@Obscura You got the World Height virtual textures to work? I get the "normal" ones to work, but the world height ones just contain 0 all the time. Have had a look at the source code of UE4 and it seems to be implemented, but I have failed to get it to work. -

Nevermind, I got it working following this tut. https://quixel.com/blog/2020/1/22/blending-megascans-assets-in-ue4 The only thing I did differently was to use a second VT for the world height and put the virtual texture num LODs up to 7. Results are as good as the distance field. :) -
Re: Ue4 - Terrain Mesh Normal Blending with Virtual Textures Guide!
Hey, thanks for your reply. I did it this way because it was the only way i knew. Yes distance field is expensive but i thought if i develop a game i would use vertex colors instead. I wanted to do this guide because i worked on it for some time so why not share my knowledge. I see that they added "world height" option to… -

Going to play with this tonight, thank you! -
Re: Ue4 - Terrain Mesh Normal Blending with Virtual Textures Guide!
the world height can be used together with the world position node in the mesh materials. It could fully replace the distance field sampling. -

Nope... watch this video. It will help: https://youtu.be/OP3m-LY6BZA -
Re: Ue4 - Terrain Mesh Normal Blending with Virtual Textures Guide!
No... create a master material as found in this tutorial video and you'll be golden: https://www.youtube.com/watch?v=_u-HdkJ3woE You can get results similar to that found from the OP but without having to switch Distance Fields on. TBH, if you're working on a large open world, then you'll probably have DF's on to help… -
Re: Ue4 - Terrain Mesh Normal Blending with Virtual Textures Guide!
Do I need a separate material for EVERY mesh I w ant to get blended? Lets say I piut a stone on my landscape and ajdust the parameters to make it blend nicely. Now I take the same stone and ut in somewhere else, but higher or lower coordinate-wise. That means this same stone need a unique maetrial with adjusted parameters?
