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"

Using a reference image on a heightmap


I am currently creating a map for Unreal Engine 4 which is based off a real life location. I am using an image of a map as the reference for the construction of the map and I wish to put this image onto a heightmap and then model the city on top of the heightmap using the image as a reference for drawing roads, placing building, etc. I already have a heightmap of the real world location and a map of the exact same area as the heightmap (for those interested I used ordnance survey data for achieving this http://r3dstar.co.uk/?p=231). When I apply to the material of the map texture to the heightmap it (unsurprisingly) tiles like this: http://gyazo.com/e01c4f685808ce9c0299f779a6ec5ebb http://gyazo.com/6b2b90a95ded8e0dbd20b25334ca9bed . What I want is for the texture to cover the entire height map with no tiling at all. Is that possible and if not is there a solution to the problem?

Use a landscape coordinate node for the texture's UV input, and set the tiling the same as the resolution of the landscape.

Try with custom UV type set to "None."
