First pose the bone so it point towards the node you want to make corrective shape key for. Select the corresponding shape key (The value should be near 1.0). In the 3D view, switch to edit mode, move the mesh vertices to a better position. When done, switch to object mode. Repeat the second set of steps for each corrective shape key. Hi all, i merged and converted two old scripts, to let you make corrective shape keys. The first script was created by Tal Trachtman (http://www.apexbow.com/randd.
In some early deformation tests it became clear quickly that rigging our fat characters was going to be a challenge. For skinny models bones correspond well to the different parts of the body, but for fat models they do not, and there is a lot of overlapping influence. With a lot of corrective extra bones and shape keys we might have been able to get reasonable deformations, but part of this project is of course to tackle these problems head on, instead of having our artists waste time endlessly tweaking the deformations! So we decided that we needed a mesh deform modifier, as detailed in.
A known trick in rigging is to use lattices to e.g. Get smoother arm deformations. But lattices are restricted to have vertices in a regular grid layout, which doesn’t fit an entire body shape, whereas with a mesh deform modifier a mesh with arbitrary shape can be used as a lattice. Erdas Imagine 2012. This way we can make the armature deform a low poly cage mesh, which in turn deforms the actual model. Using a lattice between the armature and the actual mesh smooths out the influences from multiple bones, and so gives better deformations in difficult areas. Of course the result of this is not always perfect, and we still need corrective shape keys (but fewer).
Taxi 5 Subtitrat. Such shape keys can also be made on the cage mesh, which has much fewer polygons. In addition the vertices of the cage mesh could be used for e.g. Game Plants Vs Zombie Untuk Pc. Facial deformation controls. How this modifier integrates into the rigging system is still being worked out. For example hands and fingers are being deformed directly with the armature modifier, and blended with the mesh deform modifier using a vertex group. This however conflicts with the dynamic binding that was added to make shape keys on the mesh work, so we are working on a better way to blend modifier deformations.
A using mdef can be downloaded. Note that this is not a complete rig, the deforming bones can be manipulated directly, but the high level controls for this model are not finished. Also this requires a very recent blender SVN version to work (preferably built after this blog post). For further information read the. There have also been various improvements to make b-bones squash and stretch better, a for inverse kinematics, and easier for the colorblind. 36 Responses • Writes: This is great stuff, I wish I had this tools when we did the rigs for Plumiferos:) Congratulations to all you guys!
• Paul Writes: This looks great! I’ll have to download the latest SVN release now, to really play with it. • metalliandy Writes: WowNice work peach team:) I am always amazed with the speed of the Dev’s and the constant progression in Blender. Keep up the good work guys:) • Writes: I’ve died and gone to heaven. Awesome work Brecht:) • Writes: WOW, just WOW! • toontje Writes: Last year as I read the paper, I wondered what that was good for. Awesome work Brecht, and also thanks to the Pixar devs for publishing this cutting edge technology.
Now to test this stuff on the Stop Starring examples. • Sergeant Oreo Writes: This looks very interesting. Thanks to the coders and Pixar! =D • socceroos Writes: Very nice. Its good to see that you’re not skirting around problems by writing up hacks that leads to crappy software. Keep up the good work! • nozzy Writes: Great work, a real boost to the rigger arsenal.
