2 car morph
show user profile  mynodelic
Hey guys,

Here's what my project about and you tell me which is the best way to do it.

I have a camera movement around a car which will morph into a new 2014 model of the same car.
The morph will happen when we are close to the rear window ( camera frame : rear side window and a bit of the rear windshield).
The polycount of both cars are so different so I don't have any idea of how i will morph some parts of it.

I tried to animate the vertices but it looks awful

any tip? thanks

rendering both vehicles, and then comping it in post ?

I dont have any idea of the level you are on. But actaully morphing one car model into another sounds like a fairly large job, especially if they are highpoly realistic models.

Terribly boring signature.

I think particles/blobmesh is going to be your best bet, combined prob with some fudging in post. Good luck.

You don't just need the same poly/tri/vert count to morph. You need the same vert ordering too.

This has all the hallmarks of a super cheaty cheaty post job.

animated spherify modifier

*looks around nervously, sprints off laughing*

edit- actually you might get away with it if you had zbrush, wouldn't be a big job either unless you needed the inside in which case it would be a nightmare- but car shape darkened windows no problem

Not true, k-tonne, as when you export to zbrush then import to max it changes the vertex order.

The way to do it is with graphite modelling tools ->conform.

1. Duplicate the mesh with the higher vertex count.
2. Open graphite modelling tools -> freeform and pick the other model.
3. Use the conform brush to shrink wrap to your lower poly version.
4. Easier said than done.

[edit] here's a quick vid.

'car shape darkened windows' using a zb mesh project to one car shape, add a layer and project to the other- export both new mesh shapes and they will morph in max
didn't mean use the original meshes at all apart from duplicating the shapes
it's unlikely however this method will reproduce the finer details required without a pretty high poly mesh

I'll try it, I'm pretty sure your vertex order will still be screwed (though, maybe equally screwed, so that'll be okay)

I've worked on a few projects where cars (or other objects) had to morph from one to other.

One approach that seems to work pretty well is to make morph targets for each of the vehicles to squish them into the general shape of the other vehicle. Use a lattice , soft selections, shrink wrap, or anything else you can think of to get vehicle A to be a similar shape as vehicle B. Doesn't have to be perfect, just get it close. Now take vehicle B, and do the same thing, make a morph target that squishes it into the shape of vehicle A.

Key the morph targets so that both cars go from shape A to B in the length of time you want the morph to happen. Render out each vehicle separately for the entire length of the morph. Now in post you can start blending and fading the two together to get a nice transition from A to B, use beziers or noise patterns or whatever to have it fade in and out at different times if you want.

We also used an old program called Elastic Reality, a nice 2d morphing program. That helped tidy up some of the details that aren't perfect on the morph target. ER isn't sold anymore, but you may be able to find old versions of it, or programs that are similar.

This works pretty well when you have two objects that don't have the same point count, two entirely separate objects. -

@ K-tonne it sounds like a good idea. I have zbrush but not that expert with it I usually use it for detailed object thats all.
Can you make a small video like Herfst1 did? it was very helpful.

Herfst1 thanks a lot. I tried this it worked fine until i started conforming the edges. Anything in the middle of the object was fine until the edges got messed up.

Error404 This is the best so far but im afraid how it will show in the final render since m not the compositor of this job plus the camera is very slow and nothing will happen fast.

Thanks guys I still didnt get it right so if there's anything else would b much appreciated.
