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"

Shadows rendering incorrectly (displaced) with Instanced Static Meshes

Hi all,

I'm using a Blueprint class to generate a random maze. It has two instanced static mesh components, Floor and Walls, that each build a tiled-based maze depending on a given input size. However, as you can hopefully see from the pictures, the shadows are not correct - looking almost as if they're displaced slightly, with the shadows from one wall peeking through under the next. Any thoughts?

Both instanced static components are set to Moveable, as they do not render at all if set to Static.

That looks like a bias issue. This is an inherent issue with shadow maps, although there are various methods you can use to reduce the effect such as:

  • Lower the max shadow distance

  • Raise the number of shadow cascades

  • Raise the shadow map resolution

  • Make the walls thicker

  • Adjust the shadow bias value

Or you could consider switching to either static lighting or raytraced shadows, depending on whether you need the lighting to stay dynamic.
