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"

spherical Terrain Material Problem

Hi, i have a little Problem with my spherical Terrain. I made a Material with layer blending. The Problem is, that the blending doesn't work the way i want it. It should paint the "higher" terrain with the stone color and the "lower" terrain with the grass color. How can i change that? I used the Unreal Wiki to achieve what you can see. I guess its a Problem with coordinates. Here a Screenshot: alt text

Can you help me with the planet's landscape? I have the stuff you need. But there is no geometry, I did not know that it is impossible to raise the landscape using the height mapalt text

For me best way to learn is study ready project, good done. You can check two Epic projects: Racing Game and Landscape Mountains (in learn tab). Here you have rocks with material where snow or sand is placed on top only, you can easy change it for grass (I think this is already in Landscape Mountains). So you have best sample here, just import projects (free) and try. I use similar way for my landscape, rocks and other assets, works great.

And can you help me with the geometry for the planet, I want to make a geometry with a height map

Unreal Engine world is based on flat geometry, so it need a lot of changes, math and maybe changes in engine. You can do it in C++, maybe plugins, but this is not easy and if you are new in UE and programming, if I can suggest, try easiest ideas. You can read this thread for example https://forums.unrealengine.com/development-discussion/content-creation/89568-creating-planets-where-to-start here some talks about planet creation in UE. I think nobody can help you with this question in single thread.

I already have gravity, and it has been applied so far only simple sphere. I need geometry through the elevation map because I have a map. problemo ONLY in geometry. It is true then it will be necessary to make third-party AI....

Ok, I don't know, your gravity system changes coordinates or not and I can't see your materials blueprint. You post image and I see here effect you need, this is not clear for me where is problem? This is your sphere or from other sample? You said, you need rock on top, grass on bottom - this is on image. Maybe I don't understand. Post also link to this tutorial, will be easier.

По порядку. 1. Я не автор темы, просто я смотрю вы разбираетесь, у меня есть сфера, просто сфера с UV, а мне нежна сфера с геометрией, которую я должен получить с помощью карты высот. 2. Гравитация по вот этому ролику, правда мне пока не удалось применить к чему то кроме простой геометрии https://www.youtube.com/watch?v=CMKhn8OWpXc&t=64s еще есть такой вариант https://www.youtube.com/watch?v=6z5xkJehRMg&t=2s
