Anyone know how I can create this effect? its the torn tissue that I am interested in. I dont think it is a 3D model. Is it some sort of crumpled plane with texture and opacity? Any insight would be much appreciated. It might not have been created in 3DsMax.



Full video here.. the tear is at 0:50secs

I've been thinking quite a bit about this, which is why I haven't replied sooner. I wonder whether the detached state is merely a second version of the original state with just a large number of vertices moved around, and a different texture on the arm bone showing the whitish patches where the attachment had been. It's also possible that some of the poly modeling tools have been used to reshape the original tendon. It would make much more sense than creating a second version from scratch.

Hi Joe,

Thankyou for your reply. Its an interesting effect with big potential. Maybe parts of the model have been brushed away and rotoscoped in a compositing package? I am struggleing to create a realistic ligament tear.. this is my model, so far I have just experimented with upping the iterations and moving vertices around to form spikes that kind if fit in with each other. I have also played with crumpled planes and opacity maps but nothing looks great. I am thinking I am going to sketch out a detailed tear and try to model/texture it in detail, time consuming stuff for such a small detail! maybe another piece of software like mudbox would help here. I will need to animate the tear also. Any last bits of advice would be greatly appreciated.

Ashley - I have a few thoughts on the animation, but not much specific to techniques. I would assume that the before the tendons rip, they stretch to a point, so you might animate a stretching tendon, to a point, then maybe in your compositing software, do a fast cut where they actually separate, and have the final state of the tendons (as shown in your screen grab).

As far as getting the broken tendons with their filament look, I know that there's a feature in the Poly Modeler (Graphite Modeling Tools) that will give you some powerful tools which may be useful, such as the Repeat Last command:

You might also be able to make use of the PolyDraw Panel:

Good luck with it! This is a complex modeling and animation project.

I just had another thought - you could make your tendons a whole lot more detailed with the filaments by just painting up a custom texture map which is solid in the body of the tendon, but then becomes filamenty (no such word, but you get what I mean) as it goes toward the ends where you've pulled the vertices. You might even animate the texture map so that as it stretches to the breaking point, gaps start appearing in the tissue. It might save a lot of modeling detail.

Thankyou for your help Joe. My mind is instantly buzzing with ways to move forward. I really like the idea of animating the texture map. I will post up the end result if it is worthy :)
