weird scene handling during build process

Unity Engine

Hi,

during build process, I see in the log file info about opening scene and unloading unused assets, e.g.:

Opening scene ‘Assets/Scenes/Sim4Environment.unity’
Load scene ‘Assets/Scenes/Sim4Environment.unity’ time: 0.012048 ms

There are 2 problems:

  1. build process is handling all scenes in project (doesn’t matter, whether they are specified in build settings or in input arguments for BuildPipeline.BuildPlayer, or not)

  2. it looks like each scene is handled multiple times and it takes quite a lot of time (several minutes)

Does anyone have the same problem?

We are using Unity 5.3.4 p4 on windows 7.

Thanks a lot

Ok, we found the issue. It has something to do with QHierarchy.
The developer of the extension is going to fix the issue soon.
