LOD for grass is always turned on even if it is set to off :

I’ve tested it on my end. You can try re-recording with a higher resolution (1080p) for it to be noticeable and check if this occurs to your final render.
Hi @Clov you use custom grass object I said about D5 built-in grasses.
I noticed that this issue is related to some grass models like GrassMaterial 11
GrassMaterial 04 the same :
grass material 04 (2).zip (2.3 MB)
Rendering is fine. This is why my final rendered grass looks different.
It looks like some of the grass objects override viewport LOD settings.
I don’t know what to say about this 
completely_buggy_grasses.zip (127.9 KB)
Affected objects ( Material LOD bug ) :
GrassMaterial 01, 02, 03, 04, 06
LOD bug - all of GrassMaterials
These objects use constant predefined materials on distance >1m. Completely ignore all material custom settings !
GrassMaterial 02 is even wrong rendered on final not only in viewport.
not only related to grass : jatropha integrima 05

Hi @Smolak
Thanks for this. I just tested the Grass materials that you have mentioned. The only asset with an issue that I can replicate is GrassMaterial 01, which tends to change material color when zoomed in.
- Using the same file and testing it on another file
- GrassMaterial 11
As for Jatropha Integrima 05
- The flowers are lost when zooming out, even with LOD Disabled and having a large cull distance preview. This seems like an issue reported before with other vegetation which was resolved.
I don’t know how you tested this but as I said near ALL grass materials are affected. Not only geometry LOD but all material settings too - not only color. Specularity too.

GrassMaterial 11 has geometry LOD issue when you zoom in-out on small distance you will see that grass blades are change a little. This is more noticeable on final render compared to viewport when dense grass 11 is visible from large distance.
