Hi, I meet a problem in v4.26 with niagara. Using sprite render with a asymmetric material and “custom facing vector” facing mode， the orientation of the sprite will rotate 180 degrees when I turn my view up side down. I attach some screenshot below

this is the sprite render I use

the red cell of the sprite faces up

the same sprite with camera view up side down, but the red cell faces down

Is there any shader code in the material of the sprite that handles camera facing, or is that simply just using a texture?

it just uses a texture
