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"

Is it possible to statically light both sides of a single plane idividually?

I am wondering if there is a way to light both sides of a single plane individually or if I'll need to add thickness. What if I was to make a large curtain? Will I need to add thickness to this and double its poly count?

a plane has no geometry on one side so there would be nothing for the light to interact with. there may be some material settings that you can mess with though that may help.

Thought so. I assumed that the 'Two Sided Lighting' option in the mesh setting would does some magic with the mesh and double it up or something but guess not. I think the best way to go would be just to use thickness then.

Meshes with thickness are the best! ...many times you can get away with two sided lighting as you've tried or 2 sided material...

It seems thickness is the best way to go, thanks.
