[Daydream] - 4.12 crashing project: Assertion failed when manipulating 3D Widgets
I followed the instructions from: http://docs.unrealengine.com/latest/INT/Platforms/GoogleVR/QuickStart/index.html
which works fine for a new blank project created in 4.12 however when I imported my project (that works fine in 4.11 for GearVR), I get the following crash at seemingly random positions - however always within approx 10-30secs of starting the app and inserting into my cardboard:
What is causing this crash?
oh, actually it will take longer to hit github because it was submitted into a branch.
I'll just describe the change so you can make it locally rather than wait a few weeks.
Near the end of the function ResolvePendingRenderTarget() there is a line: RHICmdList.Flush();
Change it to: RHICmdList.ImmediateFlush(EImmediateFlushType::FlushRHIThread);
Are you using the experimental 3D widget feature, by chance?
