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"

[Feature request] Speedtree horizontal billboard

Currently there are 2 problems with imported speedtree meshes:

  1. There is no top-down/horizontal billboard set up

  2. The transition between LODs and Billboard is just like switching a mesh which looks terrible.

It will be great if these 2 issues got fixed in the next update. When it comes to a top down view like aircraft or straight down view mountain or buildings, the speedtree billboards really sucks.

For the LOD transition, I think there should be an option to do smooth LOD transition for any meshes, not just speedtree. An option to enable crossfade LOD transition like unity would be really nice!

Edit: I almost forgot about the dithered LOD transition. It wasn't working for me because I didn't enable it on branch material. LOD transition working just fine now :) Just need the speedtree horizontal billboard now.

Looks like you're using 4.19, so you can use SpeedTree v8 (https://store.speedtree.com/ue4/). When exported for UE4, a horizontal billboard is included in the billboard mesh.

Also, if you choose the painted foliage lod setup on the import dialog with v8 SpeedTrees, it will set up dithered LOD for you.
