I agree that the speedtree grass may look too bright, in that image, although it blends in nicely with the starter content grass material. The starter bush is somewhere in between the speedtree and the Open World grass.
For lighting setup I am using the direct light + sky sphere in the starter level with default settings, no adjustment there, added a skylight. I wasn’t building lighting or using a light importance or post processing volume. I checked Generate Mesh Distance Fields. Are there any other light settings I should post?
The image upload isn’t working for me now so I’ll try later.
