New Tree LOD flickering

[Deleted49413338User]

I made some tree lods for pines cos I wanted to use Billboard creator and screeshot the actual pines and make as close to possible LODs for the Meshes used in Boston Natural Surrounds (but retextured)

 

The meshes match pretty good. There is a weird transition where they match perfectly to whatever they fade into and then do a sort of secondary, not so subtle pop into the final mesh. It still matches but the transition is just not subtle.. That is just the game tho, I guess.

 

Anyway my question is that these new tree lods have a flicker on them, depending on which direction I am facing. It is fine if standing still while facing in this one certain direction but If I start moving they flicker. heading on a different compass bearing altogether is fine.

 

I think it might be to do with sun and direction of sun from guessing, so far only tested this on a clear day.

 

My lods are made from the Hero Tree LOD mesh (vanilla not DLC) that is double sided.

 

I will start testing stuff but its a hassle of course to edit one property at a time on many nifs, lod game and see if it makes a difference each time.

 

Hoping someone might have an answer.

 

First thing I would guess to try is the Cast Shadows Flag, It is present on the hero tree nif so present on all of mine, not sure why lod objects need to cast shadows? but I'll be lucky if my first guess fixes it.
