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"

Lighting Issues

Hi, thank you very much for lending me a little bit of your time by readig this. I'm having some serious lighting issues which are driving me crazy. With some meshes I just get blocky and horrible shadows. When I make my mesh I always use 2 UVs, one for the unwrapping and the other one for the lightmap (I follow the guidelines of padding, aligning with the UV grid, spacing, etc). All the settings are set to Epic as well. This is a picture of my lightmap. Since this a simple object I just use a 128-res lightmap and the index coordinate is set to 1 so that it uses UV channel 1, which is my lightmap. alt text

These are the shadows when the lighting hasn't been built. That's how they should look. alt text

But...this is how they look when I built the lighting using a static light. Just horrible. alt text

Building lighting using a stationary light gets rid of the blocky edges but it still looks horrible. alt text

Raising the resolution of my lightmap to 1024 makes it look better but this is not an option. I can't afford to use such a high-res lightmap on such a simple object of my level. Besides, I've seen meshes using 128-res lightmaps look better than mine using a 1024-res.alt text

I also use a lightmass importance volume that cages the scene but it still looks the same. Could my lightmap be wrong or have some flaws?. Any suggestion will be appreciated, thank you very much in advance and sorry about my English. It's not my native language :)
