Creating interactive grass / hair in v. 15

[Brian Jones]

you should just have to put a Hair Collider tag on the object you want to push the grass around. Collisions are on by default in the Hair object.

this doesn’t work… i have tried the following:

a1) applied ‘hair collider” to sphere as well as a rigid body dynamics tag (because if I don’t add rigid body, it doesn’t move at all)
b1) created a landscape object, applied the architectural grass material to it. also applied ‘collider body’ tag to the landscape object (because if I don’t, then the sphere just drops straight through)

using this method, the grass is completely unaffected.

i have also tried replacing step (b1) with step (b2)

(b2) created a landscape object, applied the hair material to it. applied ‘collider body’ tag to the landscape object (because if I don’t, then the sphere just drops straight through)

so what am I doing wrong/

never mind i found a solution:

can’t use Architectural Grass for this, it’s a specialized quick grass that doesn’t have any collision settings – no settings at all except the settings in the material. You have to use ‘real’ grass.
