View Full Version : 2 rigs 1 character

Ok, I want to make a character and rig him. Pretty straight forward. The fact that I'm making a powerful wizard is what makes it difficult. This particular wizard likes to make use of a powerful spell which replaces his normally bipedal legs into that of a metalic spider. So, basically, what I want to do is change his rig for the legs from bipedal to metallic spider legs. I have in mind using a tblurp node and TP to magically transform the wizards legs into the spider legs. How would I go about altering the rig to achieve this effect. Or, in other words, how can I alter the rig in mid animation from 2 legs to 8.

I spend a lot of time on the forums reading and searching and such ( I should probobly get back to cinema), but I've never heard of anything like this and I'm at a complete loss as to how to do this.

Thanks in advance for any ideas,

Daoine

I would make two rigged models and switch their visibility when you want the character to transform.

Yeah, I thought about doing that. The only problem is that the transformation itself is part of the effect. As the spider legs form out of the origional legs, it will end up forcing the wizard upwards (from the torso up). That's why I wanted to use the tblurp node. I want his legs to turn into a swirl of particles (which will flap his cloak around in the process), which end up forming into his spider legs.

Oh yeah, while I'm on it, is there a way to turn geometry into a TP group and then into the second geometry using tblurp?

The magic is the main effect I'm looking to create.

Thanks,
Daoine

Maybe have three models: The fully rigged wizard, the fully rigged wizard/spider thing, and a model (not rigged) that is the morphing stage that you can use to make the transition only.

For instance, the rigged wizard stands up, stretches his arms to the sky (or whatever), then replace with morph only model in that same position, do the metamorphosis, then end with the fully rigged spider.

Just an idea...

Sounds like a job for compositing to me using the magic spell as a transisition between 2 fully rigged meshes

The way I want to do it is to have my mesh split from the waist down. Pblurp it into a vortex of particles and from there into the spider legs. The rig hierarchy is where I'm having the trouble. Perhaps I could keep the origional rig, maybe with some clever xpresso make it influence the spider legs (each leg IK chain of the origional leg rig would affect the 3 legs on each side of the spider mesh). The wizard will be wearing a cloak using clothilde, which will be blown up and around by the transformation. It's a pretty complex setup, I know, but I'm dying to pull off this effect.

Thanks,
Daoine

What you're proposing is probably possible, but it's waaaay more complicated than is necessary. As suggested above, use four models: two rigged and two unrigged Animate the bipedal character, then swap it with the unrigged biped, then blurp it into the unrigged spider, then swap that with the rigged spider.

I haven't tried it but I don't think PBLurp would work with bone deformed characters anyway.

Thanks, Adam, that sounds quite a bit simpler than what I was thinking and still getting the same results. Now to uncomplicate the clothilde part of it.

When an object is made invisible, would it still be considered as a deflector for the cloth? (either by way of checking the visible buttons or by way of a tag).

Thanks guyz for all your suggestions, a real help!!!

yup, it does. remember the clothilde-ghost-scene? i think, it came with the demo-version of R9...
the 'real' ghost was set to invisible, but dragged the sheet along as it was flying around
