Sad thing about jiggleBoobs...erm bones is, they work only for single bones. Means Boobs, antennas, some hair, some parts of the clothes are fine. But for example piccolos cape would near real cloth physics. Doing that is not that hard, what prevents us in adding it is..setting the shit up. We can't rly use any fancy tools for that because we still have to work with the HL model format(well extended and modified, but still). In short..we have no fast and not mind****ing way of determining wich vertices belong to his cape and how they are connected to their neightbour vertices to form a simulateable mesh for the physics.
And well then there is also collision and our fast movement. Many cloth sims and physic sims break down at high velocitys.
But jiggleboobs are easy to add and allready in. Their effect is just to subtile to show it.
Oh and gamma correction is in for about uhm 3/4 year now^^
And for all who don't know PBR is physically based rendering. It means that stuff as lighting is energy conserving, light bouncing of a surface can't be brighter than the light wich hit the surface. Also it uses equations wich are physically plausible/realistic.
It makes it easier to predict how different materials, as reflective surface, metals , non-metals, behave under different lighting conditions, like day/night
