Hi! I'm trying to create an animated crack effect using the L-system. What I did was project the L-system mesh onto the surface I wish to crack. What should I do next? Is it possible to do the cracks this way?

Hi! I'm really interested in doing a crack simulation similar to the one in this video: I've tried using voronoi fracture but it's more for complete destruction. Is there a way to control the cracks? Any ideas as to how I can do this? AttribTransfer maybe? I've heard about image generated cracks as well.

I import a animation model from maya and crack it now I want put the animation back,but it's not ok for the rotation you can see my attach file Can you help me to fix this,THX All! od_force.zip

Hi. I'm completely new to Houdini animation tool and i only know few things about animating anything. I have searched tutorials over google and i have only found some stuff, but not enough. So i decided to ask some help from here. Any help? ( Btw sry for my english )

cmiVFX Releases New Houdini Destructive Cracking Techniques High Definition Training Videos for the Visual Effects Industry Princeton, NJ (May 1st, 2013) cmiVFX has released their newest lesson Creating Cracks Digital-Asset in Houdini. Voronoi fracture is powerful but also has some limitations. How we can have full control over the shape of the pieces? How we can make animation for crack propagation? How we can break only certain parts of an object while other areas remain intact? In this lesson Mehdi Salehi reveals a new VFX technique in Houdini. In this lesson we will create a new digital asset to answer these questions. This new tool can use patterns for creating cracks. You will learn that almost anything can be used as the pattern. For example, You can use lines, L-system or image files as the pattern. You will learn our new digital asset has even more power. It can be used to create precise tear patterns for cloth simulation even for low poly objects. This lesson offers new exclusive effect technique which is recommended to all Houdini users. VIMEO TEASER HERE: https://vimeo.com/65339465 Short Description The aim is to create a tool to use a predefined crack pattern such as image files, wires or L-systems for cracking an object. No previous knowledge or experience is required to easily follow along. Mehdi Salehi tackles several examples to cover Rigid body and cloth simulations using this new tool. NOTICE TO VIEWERS: (No previous Houdini knowledge is required to follow this lesson. Crack Digital asset is included.) |||||||||||||||||||||| New Houdini Destructive Cracking Techniques |||||||||||||||||||||| ---> http://cmivfx.com/tu...king Techniques Chapter Descriptions Introduction A quick view on all chapters. It Shows where we start and where we go; A map for our great adventure!!! Basic Knowledge This chapter gives important clues about images and Houdini. It shows you how Houdini can give life to still images. It is our starting position. Creating The Asset In this chapter we evoke the power of COPs (channel operators)! This chapter shows you the main idea for creating the crack digital asset. It teaches you how to use the crack pattern for creating precise cracks on an object. Anything such as L-systems or curves can be used as a crack pattern. The power is that precise cuts are possible even for low poly objects. Crack Asset And Rigid Body Objects This chapter talks about simulating the pieces created by the crack asset. It shows the problems of using fracture rigid body dynamic and how we can deal with them. Also, you can see how cracks can be animated to create a crack propagation effect. There are two examples here. In the first example, the chapter discusses about how to use the crack asset for breaking a car window. You will learn how to create crack propagation and also how to simulate the pieces. In the second example the chapter talks about using the crack asset to break a bottle. The cool thing is that only specific area of the objects affected by crack asset and the other areas remain intact. A powerful feature for rendering broken glass!!! Crack Asset And Cloth Objects The other possible use of the crack asset. A journey to cloth simulation! This chapter shows you how this new crack asset can be used for cloth simulation. Now it is possible to create precise tear patterns and then simulate them. You can even animate tearing of a cloth object. The cool thing is that the cloth object can be a fairly low poly object. Also this chapter shows you some important notes and tricks about simulating cloth objects. About the Instructor My name is Mehdi Salehi.
