Height Blending Material Layers [UE4, valid for UE5]

In this video I show an algorithm useful to blend two or more materials using heightmaps data.
This video is a follow-up of my older one: • Blend Materials in Eve...
Check it if you're missing something I don't explain here.
You can use this to obtain a better quality on your landscape material, especially if you're using Megascans textures, since they always come with an heightmap.

Amazing tutorial man!! Thanks!

this is way more complex way of doing it than how it is done now in landscape painting in ue5

Great video man, keep up the content definitely a sub from me! Would be nice to see a video that maybe elaborated on this technique and added a third map for water for puddles etc?

Is there anyway to push the values of a range to 0-1? example... i have a heightmap that ranges from 0.45-0.7 and want to squeeze these values to 0-1

@VisualTechArt 2 года назад

Not automatically, since it would require to know which are the lighter and darker pixels of the texture, which is something that you can know only by sampling all the pixels... If you know those values in advance you can just subtract the min and divide by the max. That's how you normalize

@Lurreable 2 года назад

This is really great, the result is fantastic. As someone else asked here, would it be possible to use this in a landscape material, on the paint layers? As a beginner, how would one go about that?

@VisualTechArt 2 года назад

I briefly explained how to approach the problem in the comment you're probably referring to. Anyways I'm planning a more specific video on this question for the future :D

@VisualTechArt 2 года назад

Just to give you an idea: blend two layers by using a paint layer as alpha, then blend the result with a 3rd layer using another paint layer and so on. My advice is to do that with non weight blended layers, since otherwise you have to go through more complex stuff to not get visual errors like layer bleeding into each other.

@Lurreable 2 года назад

@@VisualTechArt Looking forward to the video! I never did manage to get this working as a landscape material, but it looked great as a regular material. Still the nicest texture blending I've seen.

@Lurreable 2 года назад

@@VisualTechArt One thing I found with this blending is that it darkens the textures, probably by 20% or so.

@VisualTechArt 2 года назад

@@Lurreable The video will come eventually :) For the colour darkening I can't think of why it should happen to you to be honest... Maybe you forgot to clamp the alpha mask between 0 and 1

thank you this is great, please make video about how to do this with the landscape material and using 3 or more material layers and with weight blending also. Thanks my friend. :)

@VisualTechArt 2 года назад

Will do that, you're not the first one to ask ahahaha

@@malebeery6832 Ahahahh please don't do that! I'm very slow at making videos and I have a long list of things to do. That will come "sooner or later", I'm afraid. In the meantime, I gave few hints on how to achive that stuff here in the comments, have a look ;)

@IbtesamSadiq 2 месяца назад

There are already 2 built-in function for height blend in unreal engine. 1st is with single height map and 2nd functions is with 2 height maps which is similar to your method. Is there any reason for recreating these functions which are already in unreal engine?

@VisualTechArt 2 месяца назад

If you're fine with what's already built in go for it :) I usually find more helpful to build this stuff by myself, both for understanding purposes and because at the end the outcome tends to be slightly different each time, allowing me to get a bit further from the usual "Unreal Engine" standard look that many games today have

@ethanwasme4307 2 года назад

How to raise/lower the transition?

@VisualTechArt 2 года назад

Not sure about what you mean

@huntsman2445 3 года назад

How would you add this height blend to landscape materials? Also if possible, could you include a download link for this please. Thanks

@VisualTechArt 3 года назад

If you want to use it on a multi layered material such as a Landscape Material you could move the blending inside a Material Function and use it for every layer. The weight gradient that drives the blending would be the Layer Sample for each Landscape Layer.

@VisualTechArt 3 года назад

I'm not producing example projects to download at the moment, even though I could start in the future if strongly requested or for more complex stuff.

@huntsman2445 3 года назад

@@VisualTechArt Okay, one more question about the blend, what is the texture between the albedo and normal as seen in this video please. At (2:00) btw.

@VisualTechArt 3 года назад

@@huntsman2445 It's a packed pbr texture that contains Specular, Roughness and Ambient Occlusion in its channels
