I’ll try to make it as simple as possible. I just learned how to do this so you may need to experiment with it. This can apply to any type of foliage too.
- Select the foliage type that you want to alter
- Now go to the instance settings and make sure the cull distance is set to 0.
- Edit the max cull distance to a suitable distance. Once you move it past 0 the selected foliage will disappear until you raise the max cull distance.
I hope this helped you.
