I am working on my Chinook helicopter mod. New to update 1.3 - and something present in the 1.3 experimental, is a weird graphical glitch which causes my mesh to quickly swap (flicker) between high- and low-quality textures irrespective of current LOD level. I tried a combination of LOD factors for the vehicle prefab to get rid of this phenomenon, to little or no avail.

It was also noticed that at lower LOD levels (ones rendering when further away from the vehicle), the texture resolution would actually get better. I believe this would have been caused by lower LOD levels having less polygons, leading to the engine prioritizing higher texture resolution. Regardless of the cause, this is a serious issue for my very large aircraft.

Update: Cause seems to be isolated to assignment of the same material more than once in a prefab, for example if there is a hull, and hull_2, and you give both of them the same material.

Update 2: Issue is less prevalent, but still apparent even with additional optimizations made to model. Material render seems to not like detailed BCR very much?
