I’ve been at this approach for a while now and it has been frustrating trying to get to grips with Godot’s rigid bodies and gravity responsiveness settings. I’d been trying to offset my wind lentil shapes such that they affect the soft body sails in a realistic way as the wind increases and decreases and the shape advances into the sail and retreats from it.
Trying to get the rigid body wind lentil / lens shape to interact with the soft body sail in any sensible way was proving difficult.
Originally I’d placed the lentil shape as a node in the root of the scene tree. I decided to revert back to the wind lentil being a child node of the hull again as having the wind lentil shape as an independent object in the whole scene tree was just not working.
This approach appears to have work, but the lentil shape behaves as if it were still the shape and size of the original spherical collision mesh it was created from. The shape appears to ignore its current lens shaped geometry.
