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"

Tiling landscape texture at different distances from the camera

Hello friends! Sorry, my English is not so good. I would like to ask for help from you. How to change the parameters of the landscape tiling depending on the distance of the camera. Can I ask you to explain in more detail how to do this. Here is an example in the screenshot, but I do not understand how.alt text Thank you in advance.

What do you need that for?

If you want to decrease texture with distance for performance you don't have to Unreal do this.

If you want to do something else you will need to tell a bit more details.

Maybe you will find this interesting:

So far I can give you more link but I will wait till you tell what you need.

Good day. My goal is that, at close range, the landscape texture has a high-quality appearance, and at a great distance it can stretch to avoid noticeable repetition. Depending on the distance of the camera.

The screenshots created 2 materials with different sizes of LandscCoord tiles, the colors are different for a clear distinction. Left side - LandCoord x10 Right side - LandCoord x1 alt text alt text alt text

So it's called mip and it's build in engine feature.

https://docs.unrealengine.com/en-us/Engine/Content/Types/Textures/SupportAndSettings

So if you are doing it for performance then there is no point as it's done already.

You can change this setting in texture asset. If your texture is power of 2 (eg: 4 x 4, 16 x 16, 1024 x 1024, 4096 x 4096) It generates some kind of lod if it's different eg 1643 x 1024 then you need to scale it. But if it's this power of 2 then it's done by engine.

I think I understood the problem. This is what I meant, watch the video uploaded to YouTube. link text

It remains only to adjust the main material and change it to a high-quality texture. If you are interested in setting up the material, I can send it with screenshots

Thank you very much for your responsiveness and help.
