Strange render issue with converted blueprint (4.2.1 -> 4.3.1)

Hi,

I migrated a character blueprint using a modular approach from 4.2.1 to the new 4.3.1. I use the github version, compiled from source and did so with 4.2.1 My current version in the about dialog says 4.3.1-0+UE4

Anyway, my character consists of three skeletal meshes. Body, Pants, Shirt. Put together in a blueprint, set aniumation, worked fine in 4.2. Opened/Converted the project with 4.3 caused a corruption(?):
the cloths render ok when near, but disappear when far away. I have rebuilt the blueprint from scratch in 4.3 and it renders fine, no matter the distance.
I have compared all settings of the meshes, the blueprint, the animation,… I can’t find any obvious difference. The render issue persists in Editor mode and even in a packaged project. I’ve tried rebuilding everything.
See attached screenshots.
What causes the error?

Thanks,
Ben

Never mind. In 4.2 blueprint the “Enable Update Rate Optimizations” option for the body mesh was checked.
I unchecked it, renders fine again.
I missed it being different from the new blueprint, and I swear I looked over the properties like 10 times… :frowning:
no idea how it got enabled though.
Anyway, this issue is resolved!
