Hi guys, new here!
I've been working on this studio style render of a Kraken Rum bottle, and obviously it uses a lot of refraction. However, upon rendering a turntable, I found that as I spin my model past the 180 degree point, my thick glass refractive material snaps and changes very abruptly. I haven't applied any animation to anything in the scene, and I can't find any key frames on anything (I've used the "delete all keyframe data" aswell).
I've attached some images of the issue below. If anyone knows anything, or can be of any help, please save me!
