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"

that link says that for a 64 pixel lightmap, you should snap to a grid divided by 64, but i think it should be divided by 62, right? isn't there a pixel of padding all around the lightmap that subtracts 2 pixels?

I did a test with this a few months ago and only found that it improved in some cases but not all. Here is a sample project I made to test this a while back (4.4.3).

I found that for the main wall it didn't improve really but the pieces where the ceiling is concerned looked better. If you're using modular pieces then yes you can improve the lightmaps by using this method. For most standalone assets it would be just fine.

It all depends on the workflow you want to take.

For learning purposes the information on WoLD is fairly accurate for anyone to get started understanding the concepts of lightmapping.
