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"

Shadow areas become lighter in lightmaps

Hi all,

I've noticed this weird problem more than once while working on my Arch Viz scene. I don't know if its a problem with having a lot of high res lightmaps or that they are uncompressed or something.

alt text

As you can see for some reason the areas where there should be darker shadows are instead highlighted instead. I can kinda seem to fix it by moving the object and rebaking but its not optimal. I was just wondering if anyone else has encountered this and found a solution.

Thanks!

Hmm the Normals are definitely not flipped and the diffuse boost is set to 1. Maybe i should try lowering the diffuse boost to under 1? Will have to test if that a good idea or not though.

No open edges either by any chance? :S Have you tried with a different material? /non reflective, not so bright color/ If you try lower/higher light build quality (Low/Mid/High/Prod) is it still there? I'm sorry the picture is a bit small: do you have the same artifact on the wall behind the chair too?
