In my end the Dithered Foliage LODs aren’t working, just change the model as the first old LODs, but even at the material change the bool to use it, aren’t working and the trees just change.
Used the Mountains demo from 4.13 open in 4.15 and this happen.
Hi, are you using Preview 1? LOD was completely broken in Preview 1 but that should be fixed in Preview 2.
If you’re using Preview 2, and you’re using multiple materials on different LODs, you need to set the dithered transitions flag on ALL materials for dithering to be enabled. In 4.14 and prior the flag wasn’t checked by the LOD code, and you would get black dithering if you didn’t set the flag.
