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"

Performance? - material with 6 material functions VS model divided into 6 parts, one material each.

Hi guys,

I have a conundrum, and I don't know what would be more efficient. Currently we have layered materials with some up to or around 6 mf's, most of them relatively simple base materials with options for tiling, normal strength and a detail normal.

Would splitting the model up into multiple uv sets and applying a base material per uv be worse off or better?

Would using multiple UV-sets on 1 model with one material and use the texcoord node to point the UV sets to material functions be more efficient than splitting up a model into different chunks? Where every chunk uses 1 material (and thus fewer material functions would be required per material).

So basically a more complex material versus more model parts and thus drawcalls?

Best regards, Käy Vriend.

Essentially it is situational and there is no all-in-one response. You should do few profiling attempts to decide.

Well, thanks. I did try and sketch a specific scenario in the description, hoping for a more specific reply though. Curious to see what the Unreal Engine devs have to say.
