Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Methods to make Roads like in Fortnite?

Hey there!

Yesterday I analysed a little bit the technical aspect of Fortnite, to maybe get inspiration to complete technical challenges. And I found the Roads in Fortnite, which I really can't say, how it was done in UE4...

It looks like it isn't the Spline System of UE4?!? The Roads have on High quality settings some Dirt at the edge, which probably could be done in a spline system and the use of vertex colors of the mesh in the spline system...

alt text

On lower settings, the dirt disappear. (Probably material-quality switch-Node.) At this screenshot you can see the roads and on the left the landscape painted road:

alt text

And now to the Interesting Part: This System does not use a Object as Spline and allings perfectly to the ground as you can see there:

alt text

Does somebody have an idea how this could be done? It maybe looks like a Spline Decal system, that we currently don't have in UE4???

Also found some corners like this:

Have absolutely no idea how this was done..

Can someone help me with this question?

I was intrigued by this too and just did some tests. Instead of using the landscapelayerblend node, I tried the LandscapeLayerSample node which actually gives you the weight number. With that you can do some cool custom stuff.

With a simple setup like this you can have nice hard edges based off a noise texture. alt text

I went a bit further and made a second texture automatically painted around it by adding 0.1 with a new floor function (to get more white for that texture).

Not great textures or noise lol, but you get the idea. That's most likely how they did their edges. I'm sure you can get it very similar with decent textures and a clever material setup. :)

Sorry for this late answer, but thank you so much! You helped us a lot!

We used the landscapelayerblend node for advanced stylised foliage placement but never thought using this for landscape texture blending...

Everything works perfectly now! :D

How did you set up the second part? The bit where he says he went further and added an additional floor node, I can't work out how to set it up.
