Hi, First of All.. Awesome course!.. Thanks! I have a question about a hair particle system I'm creating. It should instanciate an object for each hair, place it rotating randomly the z axis over the plain be affected by force fields bending itself, like for example the wind blowing over grass. Happens that when I use the Render - Group button in the particle system properties, i get to see all the instances place ok with a random rotation, but dynamics affects weird (scale instances instead of bend). So I tried a different approach and added a Particle Instance Modifier to the object itself. This way the force fields bends the particles ok, But I couldn't make the randomly rotate the positioning. Is here the right place to ask? What is the best way to achieve what I want? Is there anywhere I can share a blend file for you guys to see this? Thanks!!! TR
