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"

Instanced foliage not reducing draw calls on Adreno 330 (Galaxy Tab Pro 10.1)

When I pack for Tegra K1, everything works fine, but on Galaxy Tab 10.1 draw call number is not getting reduced - so I get ~100 draw calls on Shield Tablet (K1) and ~2000 draw calls on Galaxy Tab (Adreno 330), for the same scene.

Hi 7hny,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?

  • What steps are you taking to reproduce this on your end?

Can you please post your log when running on the Galaxy Tab 10.1 device, specifically the OpenGL version and extension string part?

UE4 supports instancing only Android on ES 3+ devices, and we also specifically disallow it if the driver version string is "OpenGL ES 3.0 V@66.0 AU@ (CL@)" because there is a bug with it on that specific device. In the case of the latter it also prints a message to the log file.

Thanks Jack
