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"

What could be the reason of the lost of 20 FPS

I have the mannequin mesh from unreal and a mesh from character creator (iclone 6). As you see the mesh from character creator has vertices count of under 3000 but with 315 on screen i get ~64 fps and on the other the mannequin mesh is more "Complex" but i get ~88 fps. Both have the same Materials.

It looks like the iclone character has 2.5 times more materials than the mannequin model does and the number of materials is directly linked to the number of draw calls which in turn affects your FPS rate. Even if the materials are blank they still count because the slot for the material is referenced during the draw call process. take a look at the number of draw calls for each of your scenes and you should see where the difference is clearly with the numbers.
