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"

Error on Build Light

Hy, I am trying to spread out a LOT of vines on a large Landscape. Since I do not know how to do them properly with blueprints, although I have tried with the ones inside the Content Examples Scene, the only problem being that this blueprint doesn't know how to align them on a rough landscape, the only solution remaining is to scatter them inside max, with Forest plugin, then copy their transforms with this script and replace them inside UE4 . But when I try to build the lighting I have an error like in the screenshot attached. alt text Does anybody knows how to solve the problem or to point me how can I make a blueprint that distributes a mesh on a spline but also knows how to align it on a landscape surface? Thank you !

Product Version: UE 4.9

I think you need use a built in Foliage system. It can place many objects on any surface with various parameters.

This is videos about Foliage.







But If you need use spline tool, you can look in this tutorial, how to spread objects with spline tool.

Hy!, Thank you for your answer. I watched closely all these tutorials, and also made the blueprint as shown in the last video. The problem is that I have to distribute my meshes in a certain grid, like in the screenshot above. I know that with the Landscape Grass Type you can spread meshes on a grid, but all the distances are equal on both axes and I want them, let's say, more tight on X and more loose on Y. So that is not a solution. All other types of folyage, from what I've seen distributes instances randomly. With the last blueprint the problem is I have to place them on the landscape and the blueprint doesn't know to do that automatically. I have tried with this setup as shown here but I am missing something. And the last solution was to use landscape splines because they are snapping on the surface of the landscape. BUT, the problem with them is that my mesh, being a vine is pretty fuzzy, with all the leaves and grapes, and when I put them on the spline they start flicker. ALso, when I import LODs they start flicker even more. So, at last I still couldn't find an effective solution to distribute my vines. But I'm not giving up on the problem...still.
