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"

Tesselation doesn't work on linux cooked version

Tesselation on linux works very well with UE4 Editor in Selected Viewport, New Editor Windows and Standalone Game with opengl 4

However when the game is cooked UE4 failed to loas material using tesselation with this kind or errors :

 LogStaticMesh:Warning: Adjacency information not built for static mesh with a material that requires it. Using default material instead.

The adjacency information seem correct and it works on windows cooked version. The cooked version use the correct Opengl version :

 LogRHI:   GL_VERSION: 4.3.0 NVIDIA 352.63
 LogRHI:   GL_SHADING_LANGUAGE_VERSION: 4.30 NVIDIA via Cg compiler
 ...
 LogRHI:   GL_ARB_tessellation_shader

Upping this issue, as it hasn't been answered in one week.

Hey Gwenn-

If you are using OpenGL4 / Tessellation inside the editor then when you run the cooked game you will need to run OpenGL4 there as well.

Cheers

We are aware of that. Please check out the attached log file - we start the cooked game with "-opengl4" and the logs seem to indicate GL 4.3.

Hey Gwenn-

I was able to create a test project and had the same results in a packaged project as shown in your screenshots. This tessellation problem has been bugged (UE-24301) for further investigation.

Cheers
