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 cause unknown x10 triscount unless selected

Recently I have got strange issue with landscape or something related to it. Getting up to 90.000.000 static mesh tris, unless selecting landscape in viewport (or enabling any other view mode than lit). Then tris count gets down to around 4.000.000 where it should be. What could cause that? There is no tessellation used.

Issue started around when I started using quixel megascans meadowpack grass that is added as grass layer in landscape material. But have checked the settings many times and have lowered triscount for those meshes to very low (using percent triangles slider). Also the grass is visible when selecting landscape (while it take tris count to 4.000.000). Also setting foliage to low dosent give tris boost even grass dissapear.

Edit: Tried to remove all grass layers and all foliage and placed meshes. No change.

98.000k when lit and unselected! alt text

800k when in wireframe alt text

2.500k when lit but selected alt text
