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"

I have Made a Landscape Collision Fix Plugin

I have developed tested and am loving my very own Landscape Collision Plugin!

For anyone having landcape issues, my plugin will fix it for you!

My plugin can either totally replace a landscape's collision, or you can choose to only patch sloped parts, and you can choose how much qualifies as sufficiently sloped!

Could be those bits are meshes with no collision mesh on them? Check the collision properties of the bits that they are falling through...
