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"

Weird Rounded LowPoly Shadows

Hello everyone, I'm 2 days into Unreal Engine so you can tell i am pretty new to everything, i did the tutorials and watched alot of videos. I was taking the first person template and deleting the map out of it. I then created a wall and a wall detail with BSP, afterwards i converted it into static meshes. My Problem: Weird shadows as in the following picture alt text Were cast. I built the lighting already but i couldn't figure out whats the problem. (editor is also set to production). Any help would be greatly appreciated! :) *Edit i just discovered that i could walk through these walls? Where do i change this.

Product Version: UE 4.15

I found the fix myself. The wrong UV-Map was selected and collision deactivated, as usual with BSP objects apparently. Increasing shadow maps will increase accuracy of shadows too. And use cascade lightning. Good video on this for everyone having problems: https://www.youtube.com/watch?v=WDM9ir3NZH4

You can select floor mesh, find option Override Lightmap resolution, and set it to 128 for example. this will give good resolution for shadow.

Or you can select directional light, and enable cascaded shadow maps in it. this will enable dynamic shadows on specified distance

With floor mesh, you meant the plane? ok i did so and increased the shadow res of the plane only and it creates this weird rounded half correct shadows alt text

Its lightmap. It will be simplified with low resolution. You can set it to 1024 or 2048, but then its memory cost will be increased dramatically.

Better enable Cascaded shadow maps
