NOTE: there is a newer version of Pulldownit with important updates in performance, check it here:
This new update of the tool has its focus on improving user experience in Maya, especially when working with animated objects in dynamics or when making small changes to scenes already baked.
For this we introduce a revamped method for animated breakable objects, this new method gets smoother transitions when the object start to fracture. Also Secondary Cracks policy is now applied per fragment, getting main block or animated parts to remain unbroken while smaller fragments split again automatically.
Now is very easy to recompute or reshatter any single fragment, so you can make small changes to baked scenes seamlessly, adding to this the baking of keys is now a background process, modifying simulations is much faster when working on destruction projects.
Several of this new features you can see explained in this nice tutorial by Esteban Cuesta,
And there are other important enhancements like shatter of combined models up to 8 times faster, and a new PDI Cache monitor to watch the state of the cached simulation or clear it if needed, last but not the least quite a few annoying bugs of previous version has been fixed.
Below listed the most relevant highlights in Pulldownit 4.7 for Maya
Shatter New Features
Shatter of combined meshes up to 8x faster, models made of different parts combined together are shattered now much faster, the speed up depends on the tessellation of the original meshes, being up to 8 times faster for hi-poly models.
New ability to reshatter single fragments of baked fracture bodies to any extend, reshatter baked fragments is now an easy action and can be repeated to any extend, besides new shards created will acquire motion of the original fragment in dynamics.
Dynamics New Features
Revamped transition animation-dynamics method for Fracture bodies, animated objects which breaks are now computed more accurately, getting smoother transitions and fine control over how and when the object start to fracture.
New Per Fragment Secondary Cracks policy, secondary cracks are now applied per fragment instead of for the whole object, differentiating in this way the bulk of the object from detached and animated parts and modulating the effect accordingly.
Allow to recompute fragments with baked keys in dynamics, user can recompute motion for already baked rigid bodies or fragments just by setting its activation time.
Speed up baking of simulation keys, baking of simulation keys is now done in a background process, this makes baking of keys much faster, especially noticeable when there are hundreds to thousands of fragments on scene.
New Clear PDI Cache UI button, user can now watch the state of the PDI Cache and remove current cached simulation if needed to start computing from scratch without modifying any parameter.
Selected Shatter group is now highlighted before confirming “Undo All Shatter”, this new behaviour gives instant feedback of which fragments are selected before undoing them.
