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"

BUG: Add instance function (hierarchical instanced static meshes)

(tested in 4.18 too)

1) Create new project

2) Create Actor with HISM component, Mesh will be Cube from Engine (100 cm length)

3) Paste simple logic with function Add Instance in the construction script alt text

4) Compile and you can see gaps between instances (approximately 4 mm) alt text

If you make instances by hand (with ForLoop values - 0,100,200 and etc on Y axis) - all is ok, without gaps. For automatic mode need to make coeficient instead 100 - 99,96 (somehow unreal past 99.959999 ).

I think problem in the "Add Instance" functionality
