Depending on what mod you're using for icebergs, glaciers, etc the full model may or may not use the exact texture that the dyndolod resources lod model uses. Also, even if it uses the same texture, the lod model can't use the same mesh flags that the full model can so it won't look the same. As a way to smooth visual transitions for this, I personally use the Glacier LOD Meshes mod and then (because it doesn't include the "_anim" lod models that dyndolod resources provides for Animated Icebergs' full models) I copy and rename the corresponding lod model to overwrite the ones in dyndolod resources. Glacier LOD Meshes uses edited lod models that retain the look of the utilized texture more accurately.
PS - GLM is an oldrim mod but since it is just meshes it will work as is.
