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"

Landscape Baked Collision Not Working

A new feature of 4.11 is the option to "Bake Material Position Offset Into Collision" of a Landscape. Has anyone gotten this to work? My editor is getting stuck on "Building Grass Maps" (no change after 10 minutes). alt text

Steps To Reproduce

Alright so I just tried it in a blank project and same problem. Here are the steps:

  1. Create 4.11 blank project with no starter content.

  2. Remove everything from the world (lights, skybox, etc.).

  3. (Optional) Create the material shown below and name it M_SineWave.

  4. Create a landscape with the settings as shown below. This should yield the wavy landscape in the bottom picture (wiregrid on the right).

  5. Select the landscape and in Details > Landscape select "Bake Material Position Offset Into Collision". It should get stuck on "Building Grass Maps 4".

Hi Turing Machine,

  • What steps are you taking to reproduce this on your end?

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?

It seems to occur in a blank project as well. I've added steps to reproduce to my post.

Ah okay thanks good to know. I couldn't find anything when I searched. When you say "UE-25359" is there a way for me to see that?

At present we do not have a public bug tracker. However, if you post back here and request an update I'll be happy to provide that information.
