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"

Paper2D - light cut in half

Hi, I'm following this livestream tutorial as an introducción to Paper2D but I'm unable to achieve a correct lighting on the tilemap. When I use a lighting source it cuts in half. alt text It happens on perspective and orthographic mode and I tried modifying the tilemap material but I can't make it work.

Product Version: UE 4.20

I am having the same issue, it can be replicated by create a new project from the Paper2D template:

  1. Create project from template.

  2. Switch to forward rendering(needed for lights in orthographic camera mode).

  3. Create a tile set

  4. Create a tile map

  5. Place tile map in level

  6. Place light in level

  7. Switch material of tile-map to any lit marital.

It does not effect Sprites, only Tile Maps.

I am using version 4.20.3

Example from starter project with issue

in editor light radius gets rendered correctly tho. fix pls :)

I believe this is a mesh normals issue since putting a Point Light behind the TileMap will cause the light to hit the front. Really frustrating and for now I guess try using Ver. 4.18 since it seems to be before this issue began.

Same problem here with UE 4.21.2

For my project yes. Before that changement, the light was only lighting the inferior part of mapalt text

thanks! heh I had forgotten to change the angle of the Directional Light, setting on 0, 180, 90 made the light work!

I've got a solution: setting the Material to Translucency seems to work, but you'll need to set the translucency priority in all sprites so they won't appears behind others.
