Away3D MD5Animation Nothing on IOS

Testing Away3D-sample MD5Animation presents a blank screen on iOS. Testing on Mac works with no issue.

Tested Away3D-sample View on IOS, and that works no problem.

So now I’m at a loss for what part of Away3D fails on iOS. Nothing crashes; just nothing appears.

hxcpp: 3.4.64
lime: 5.9.1
openfl: 6.5.3
away3d: 5.0.4
away3d-samples: 5.0.2

Any ideas?

Completely silent fail. Output is the same as on a properly working sample:

MD5Animation[1927:160314] [DYMTLInitPlatform] platform initialization successful
MD5Animation[1927:160262] [MC] Lazy loading NSBundle MobileCoreServices.framework
MD5Animation[1927:160262] [MC] Loaded MobileCoreServices.framework
MD5Animation[1927:160262] Metal GPU Frame Capture Enabled
MD5Animation[1927:160262] Metal API Validation Enabled

iOS is really frustrating like this. I wonder if we can rollback the sample (somehow) back to something that does run, to isolate what is going on. Perhaps it doesn’t like something about framebuffer use? Are there filters in the sample?
