Pulldownit 4 for Maya released!

Banner760x400-PDI4

Pulldownit 4 for Maya has been released and comes with several new powerful features you can see explained in the video.

But this release is not only about new features, the whole plugin has been updated and tuned for better performance and usability, there is now one single window gathering all fracture tools and one single window for all rigid bodies stuff, alleviating the burden of many open windows in previous version, new seams view in Shatterit mode and improved performance of fragments selection in advanced fractures, besides fracture solver is around 30% faster and much less memory is needed to cache simulations, and many other little things you surely will notice when using the tool, all of this makes this new release more responsive and with faster iterations when working in Maya.

Below listed the most relevant highlights in Pulldownit 4.

Shatter New Features 

New Adquire Shatter style, new style to transfer a current shatter pattern to another object including animation keys, by using it you can apply the current shatter effect to a version of the model with different shaders applied or to a hi-poly version of the same model.

New Shatter option for using a volume shape as source, now you can use any polygonal shape to constraint the shatter effect to its volume, this is especially useful when shattering based on an impact object.

Jagginess( v2.0) independent of tessellation.  New Jaggy method  is independent of the original mesh tessellation, getting much lighter jaggy fragments when the object is hi-poly, and removing the artifacts caused in borders of high tessellated models

New soften edges UI parameter for Jagginess. New parameter to adjust soften of jaggy edges to get the amount of roughness desired in inner faces. In addition new soften method removes visible seems on inner borders from previous method.

New option to apply jaggines to broken fragments only,  using this option for non-moving fragments you can apply jagginess only to the areas which has been broken in simulation, getting much lighter meshes for rendering or real time games.

Dynamics New Features 

Speed up Fractures solver 30%, PDI dynamic solver has been very fast since its first version, in this latest release you will experiment faster iterations when working in dynamics.

50% less memory needed for caching simulations. PDI cache is now 50% lighter in CPU memory , that makes massive cached simulations running faster in viewport.

New ability to pull apart pieces of an animated object at desired frame, besides activating rigid bodies at first hit you can now set the frame when they become active, this works also for rigid bodies linked to an animated one.

Added a bake selected option, you can now bake keys only for selected fracture bodies, letting the rest to continue being driven by simulation, baked fractures can still interact with other objects by setting the animated fragments as kinematic bodies.

Improved performance of fragments selection in advanced fractures, selection of individual fragments in viewport is more responsive, especially when Stresses View is enabled.

Cluster break energy is now independent of body mass/scale, break energy dependence on body mass made cumbersome to understand its behaviour as the same threshold will trigger a blast or not depending on the size of the object, because of this we have removed this dependency and the threshold you set will be valid forever independently of mass or scale.

First hit bodies which eventually doesn’t move are excluded from caching and baking, fracture bodies set as “break upon impact” only caches its broken or moving parts and fragments set as static aren’t cached at all , making in this way the size of PDI files smaller specially when you are collapsing only parts of large structures such as buildings.

Export PDI dynamics from Maya to UE4

In this excellent tutorial Esteban Cuesta shows us how to destroy a pile of tubes using Pulldownit in Maya and then export it to Unreal Engine 4, but not only this, he also teaches us how to trigger the destruction in UE4 when a bullet hits the model during the game. Exporting broken models and dynamics to UE4 works with either Pro version and free version of Pulldownit, just follow the tutorial to learn how to add quality destruction effects into your game.

 

thank you Esteban for the amazing tutorial

 

Breaking Letters Demos by Esteban Cuesta

These are the  breaking letters demos Esteban Cuesta made  as a final example of his tutorials on shattering text with Pulldownit plugin, you can find this tutorial a couple of articles below. Esteban Cuesta kindly explains some details about the making steps.

 

 

I wanted to make a video as a final demostration of my breaking letters tutorials with Pulldownit 3.7, I designed demo #1 as a classic letters intro, quick and lively, the motion of each word is animated until it touch the word below, then I activate the fracture bodies so pieces of letters start to crumble and fall, I used a Wind field to stress the debris falling effect. The final destruction was as easy as animating the word “Pulldownit” so it pass through the whole text and set it is a kinematic rigid body but I switched to “Convex hull” Bounding Volume to speed up the testing, the dynamics looked good anyway so I used it for the final shot too.

Doing the first shot wasn’t difficult at all and pretty funny, this encouraged me to make a longer one. This time a decided to add a plate showing the different shatter styles of Pulldownit with letters, all styles except “Wood splinters” as I think this style doesn’t make sense for letters.

 

All sets are done in the same way, using the 3D Max text tool to generate each word and making the endings fit each other simply by adjusting text size and kerning, and then collapsing all the words in a single poly object. At this point I applied the intended shatter style and create a fracture body for all pieces. For the Radial style plate I used an animated sphere to trigger the destruction, I simply hid it when rendering the scene, for the Path style I used the great crackers objects of Pulldownit as triggers, the rest of plates uses a Wind field to trigger the destruction, animating its Strength in order to get a increasing amount of falling debris.

Rendering was done using Mental ray in 3D Max, applying a high reflectance material to the letters and a less polished glossy material with the same colour to the inner faces after breaking.

Pulldownit worked very well , I haven’t any issue aside tweaking the parameters to get the dynamic behavior I wanted, It was very intuitive and fast computing using it.

Pulldownit Update 3.7

MD_Banner3-7b

Our main focus in this update has been to increase plugin reliablity and improve to the maximum several already outstanding features. All reported bugs so far have been fixed, working with hi-poly meshes for shatter and dynamics is faster and several options for fracturing has been adjusted following users experience, thanks to all that contribute to continuously improve Pulldownit plugin.

Besides Shatterit tool has been enhanced to break holed shapes like 3D letters correctly, watch shattering  letters intro and video tutorials by Esteban Cuesta

Quake at St.Lawrence Church By Luis Tejeda

Luis Tejeda has posted a new video showing a cinematic action shot where a church tower collapses during an earthquake. The scene is a recreation of the real environment and setting of the San Lorenzo Church in Cordoba, Spain. Pulldownit 3.5 was used for all destruction effects.
