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"

Make Instanced Static Meshes Face Camera

I'm trying to use instanced static meshes like billboards to reduce my draw calls. I want to:

  • Have the instanced static meshes facing the camera at all times

  • Avoid doing the rotation on the CPU

The first thing I tried was using the AlignMeshToTheCamera node in my material. This works great on my billboards but it seems that instanced static meshes are setup using local space offsets from their origin. It's not clear to me how I get their world space location in the shader to offset this.

If you use the Math Hall Example 2.21 and in the shader swap out Actor Position with ObjectPivotPoint, it works as desired.
