Rims - inner barrel paint doesn’t render, but renders on floor reflection and in-game
some finishes don't paint. Some chrome wheels only change the chrome color.
Some rim finishes barely change color or just become black.
Some rims with multiple color slots don't change color on certain slots.
Chrome or polished metal finishes don't render on some wheels.
Some of the brass colored finishes don't paint correctly. The paint blends with the finish that's already there and becomes some muted color blended with brass like it was painted with transparent paint.
Some rims when painted with a textured paint like carbon or camo display a larger than normal texture pattern that also deforms with the curvatures on the rim surface
Brakes - racing brakes do not render changes in livery editor or in-game. Always red calipers on every car
Background - there’s an option to change the background in the livery editor but there’s only one option
There is more but I’m no beta testing bug chaser. The livery editor is ripe with rendering errors or features that flat out just don’t work. Too many to count. Most rims don’t paint correctly. Not making a specific thread for each one.
