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"

Wrong direction of reflections on meshes.

Hi all,

I am having some serious problems with the reflections that I get on some of my meshes. Some of the polygons seem to reflect in wrong directions... All the objects were modeled from scratch, UV unwrapped for diffuse and for lightmap in separate channels in 3dsMax. The meshes are double checked in terms of smoothing groups, normals, no overlaping in Lightmap UVs, etc. I also checked if any UV islands are mirrored, but they are all correct. The materials are made in UE4 and consist of simple seamless diffuse textures with normalmaps - nothing special. I use Sphere reflection captures to build the scene reflections. All the scene elements (lights and meshes) are static.

I am run out of ideas why I still get some of the objects reflect in a wrong direction (example of the brown floor Piece, which is one Object made of three elements but two of them reflect somehow backwards). More examples of same issue in attached screenshots (concrete floor in the middle of the hall)

I am looking forward to some solutions. thnx in advance.
