BGE: ray casting works on soft body, the hit polygon is also returned. The modifications to Bullet have been reported to Bullet forum. Note: welding is completely disabled on soft body as it breaks the relationship between the soft body collision shape and the graphics mesh without bringing any additional stability (the reverse actually).
