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"

Dynamic Shadow from Stationary Point Light in Forward Renderer only partially visible after light bake

Before building light: Before building light

After building light: After building light

Gif of behavior: https://gfycat.com/widenextkingsnake

This only occurs in 4.17 with the forward renderer enabled, tried in 4.15 and 4.16 but the shadow works properly in those versions. Steps to replicate:

  1. Create an empty 4.17 project

  2. Enable Forward Rendering

  3. Create a big static cube, smaller movable cube and stationary point light

  4. Bake lighting

I hope I'm missing some obvious new setting in 4.17, anybody got any idea how to fix this?

Pretty sure this edit to ShadowProjectionPixelShader.usf (at line 232, as of the 4.17 release in UE4-QA) fixes it:

     float4 HomogeneousWorldPosition = mul(float4(ScreenPosition.xy * SceneW, SceneW, 1), View.ScreenToWorld);    

becomes

     float4 HomogeneousWorldPosition = mul(float4(ScreenPosition.xy, SceneW, 1), View.ScreenToWorld);
