Lottie-ios: Shape not being rendered correctly (Scale + Position + Rotation)

[lorenappin]

Hi Lottie Team,

I checked in with Bodymovin and they said the JSON was created correctly and it looks like it might be an issue with Lottie...

I'm having issues getting an animation of a Fish to work out. It uses scale, position, and rotation at the same time.

I've attached all files - the AE project file, the expected animation, and the resulting animation, along with the JSON output.

Thanks for your help!

@lorenappin What version of lottie are you on?
I just tried the animation with the most recent version (2.0.3) and the animation worked, though the background color was missing.

@buba447 Thanks! It seems that I need to update it - I see you guys made an update a few days ago.

Although it fixed this issue, it unfortunately made 80% of the project now entirely unusable with lots of errors.

I'm attaching two examples of the before and after (v1.5.2 vs v2)

1. Moving waves (now shows a very very weird rendering)
   waves.zip

2. Idle Fish - doesn't show the body.
   fish.zip

Fish + Waves.aep.zip

BTW - only in case it's convenient for you - would love to buy you a coffee and show this in person since it's likely more efficient. We're just down the street.

Hey! I looked into your AEP file. You might have sent an incomplete version. The Wave Animation composition is completely empty, not a single layer.
Also I noticed the fish composition has expressions, something not supported by Lottie.

Also, Id love to grab coffee and look over this with you in person. Im out of the office today but tomorrow sometime would work. Email me @ brandon.[email protected] to coordinate.

Theres a bug in solid layer with masks. Will investigate.

Hi ,

I think that my issue is similar to this as i have a solid shape just using rotation and and scales but somehow it does not render on iOs although it renders perfectly on web. Rotation and scaling are supported according to this webpage: https://airbnb.io/lottie/supported-features.html. I also have the latest version of lottie right now. Can you kindly see if it works for you on iOS? Below is the json and the aep. Many thanks!
