Preloading the UI is a valid workaround for this bug. In my example I preloaded the UI in a display and closed that display immediately afterwards. This seems to be fast enough so the player doesn't recognize the preloading:

The UI2Texture fix the latest profiling build 2.12.150430 does not solve my problem.

I think my ticket (https://feedback.bistudio.com/T171035) is related to the behavior mentioned here. In my case it's not a nested UI but only a static image. I tested the latest profiling build 2.12.150430 but unfortunately this does not solve my variant of the problem.

To fix this issue, display your texture in normal UI somewhere before using it inside ui2texture. I have the ticket about this exact issue @ https://feedback.bistudio.com/T170766

remove3DENConnection works now for me. The Wiki page was misleading. Sorry. I used a wrong entites array.

Today I created my first custom connections. So far so good. Unfortunately, the command remove3DENConnection crashes if I try to remove a custom connection. I can reproduce that. @dedmen could you have a look at this?
