Hi and thank you for your purchase. This exact subject has been discussed in the previous messages on the forum. An object being ignored when outside of the camera field of view is called frustrum culling. In HairStudio, the frustrum culling is naively done by creating a 1 meter sized bounding box in the center of the hair game object. This causes the following know issues: - the hair game object is required to be at the approximate center of the hair volume - the one meter size is not sufficient for longer hair - the scale is not taken into account at all. I'm currently working to fix this. The bounding box will be place in the average position of the hair roots, its extent will take the maximum hair length into account, and the scale will be used correctly. The patch will not come soon, though, so I suggest that you move your hair object in the middle of your hair volume approximatly, as a temporary workaround. With a scale of 1, you should not have any issue in this configuration. Oh, and if you like HairStudio, please write a short review on the store, it helps a lot!
