Using Blender to Crush Some Cans Tutorial

With only a couple simple modifiers, we can make Blender crush things for us! This tutorial will take us through setting up the proper modifiers on a pre-made model that will help us get the crunchiest crush possible.
The Blender can model and setup is available to Citizen members over at cgcookie.com/downloads/model-...

I work in a recycling company, i make these things pretty regularly, i always use shapekeys but i think that this workflow is a bit more flexible, i like it!

[@xDaShaanx]

Incredible tutorial. That Lattice modifier is like Wrap in Photoshop but a lot better. Thanks. :D

[@mesarena5408]

Wow I am blown away..my goodness..blender is really powerful..Nice video

[@AhmedNassef]

That was surprisingly easy!!!

[@cg_cookie]

Just the way I like to keep it! -Chunck :)

[@SourceAwareness]

Many Thanks!!

[@graphguy]

Nice

Displacement doesn't work.. Where can I show you my setup? I did every step correctly

[@krissosful]

Awesome job, keep going!👏👏

[@FrostyTheSnowball]

Following every step to the letter, and I don't get the same results. The displace modifier only barely affects the mesh. Same subdivision modifier settings shown here, same vertex group. Unsure of what else I can try, or why it isn't like what's shown.

[@billy-bg9rx]

having the same problem

[@nocs13]

blender users please recommend how should I smooth subdivided points without change base points position? I beg u.

[@SaphirYsf]

Can you please tell us your computer setup ♥️

Would this be a method to create controlled folds in clothing objects. Like say a hood on a sweater, can this make a neat fold somehow to achieve a hood on and hood off animation effect? So that when hood is at the down point, it is a folded hood hanging down back as it would look like IrL? I am creating an advanced rigged Spider Gwen model, and the animatable hood up\down shapekey morph is giving me beef, so any advice would help TbH.

[@cg_cookie]

There's no doubt that you could use various parts of this technique to help get the desired look, I'm not sure to what degree you'd have to re-configure how you would go about it though. The lattice/displacement works well here because the can is relatively straight and being crushed in one direction. For a hood, you have a lot more variation in the places that you'd be receiving tension across the fabric, not to mention that a hood get's pulled in multiple directions when being put up/down.
I think you would get more use out of this if you were to use it on an item such as a sleeve, where you can scrunch it along one direction and create creases in the fabric as it rolls up the arm. -Chunck :)

@@cg_cookie yea I toyed with this method last night. No joy. But as you say, this is perfect for a more controlled squish method. Thanks for the reply. I am sure I will stumble across a good workflow for my project eventually. Just gotta keep digging through the tutorials. It's amazing what answers you find in between other people's projects as you watch and they cover one little step in their project that's perfect for everything you're trying to do.

[@iamcaleb5544]

Is it possible to make the displace modifier have a starting strength of 0 and increasing strength the more you crush it?

[@ObscureHedgehog]

It should be possible with drivers to have one affect the other, so that the position of the selected lattice points drives the strength of the displace modifier.

[@iamcaleb5544]

@@ObscureHedgehog thanks!

[@bobogus7559]

​@@ObscureHedgehog, @I am Caleb, Another way to do it involves shape keys. Simply have the uncrushed can as the basis position, then create a keyed position, select it, and crush the can to make the crushed can the keyed position. Then, copy the slider between basis and key positions as a driver, then paste the driver into the displace strength. Finally, right click on the displace strength, click "Edit Driver," switch the driver type from averaged value to scripted expression, and enter the expression "val * -0.005" (or any other negative value you want). Then, sliding the slider will make the displacement transition as needed.

I'm trying to figure out how to make the blink portal from X-Men, any suggestions?

[@yellowfirx0]

i would just create some emission material crystal type stuff, then add the other details in photoshop.

ur website is down :/

[@mcarms3743]

how do I just get my can?

Have to be member to download it

i was literally making this a couple weeks ago... was screwing with soft bodies and everything.... >.

[@cg_cookie]

Ah man, venturing into the scary-zone with soft bodies. -Chunck :D

@@cg_cookie ikr XD. all i wanted to do was make a bunch of generic assets of crumpled cans. obviously it was a failed experiment.

But why wouldn’t you actually crush it…..

I came to see you crushit inside a vitamix. Im so disappointed.. 😩bye you all designers.
