[Solved] Edited EA Mesh looks not as smooth

Hi everybody, 

I am currently trying to get a little into editing EA meshes and I have an okay understanding of meshing and Sims 4 Studio in general. 
I tried editing some base game candles, making 2 out of 4 so to say. 
I edited the LOD 0 + LOD 1 as well as both Shadow LODs by deleting everything not needed in Blender, then I recolored the texture as usual.

Now everything looks okay and works so far, the only problem I have is, that my candles look not as smooth as the original ones. I run the game on ultra settings, if that's important?

I think it's something about the shadow, but I can't figure out what I did wrong. I'll be glad for any help! 

Here's the .package for further investigation: www.simfileshare.net/download/846754/


Thanks in advance
