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"

Load / unload Stream level crash

Build Type: Binary Unreal Launcher

Build version: 4.14.3-3249277+++UE4+Release-4.14

Detailed description of the issue: Got stuck in a big project where we used Lighting Scenario's to easily switch styles in an apartment. Everything works like a charm in PIE mode, but unloading/loading these streamed levels crash in standalone or packaged version. Happens 100% of the time.

Decided to test the matter in a new project to limit influencing factors. Started from the first person controller template and made the most simple lighting scenario switch I could imagine. Works in PIE. Crashes in standalone. 100% of the time.

Added testproject as Attachment Link

Basically unloading + loading another streamed sublevel set to lighting Scenario, in one blueprint call, crashes 100% in standalone...

Repro Steps

Action 1: Create New project from First Person Blueprint template

Action 2: Create 2 new levels, add a mesh in each in a different position, add them as sub-levels to the default persistent level, set as lighting scenario, and build lighting separately for each scenario.

Action 3: Use Load Stream Level and Unload Stream level in one blueprint event. (level blueprint or any actor or UMG blueprint is fine).

Action4: run in standalone mode, activate above blueprint event-->crash.
