Tutorial - Cloning the shape of an object through UV coordinates (mid)

In this tutorial we will create a maya python script that takes two meshes A and B and makes B look like A using the UVs to create a correspondence across the two meshes.
The more the two UV maps are overlapping, the better results will be achieved.

This is the second tutorial that should lead to creating your own UV blendshape deformer in Maya. I am doing this as many people asked me for my UV blendshape deformer.
The first tutorial of this series is available here.

Tutorial - Using Open Maya to set vertex positions to match UV coordinates (easy)

This is the first tutorial that should lead to creating your own UV blendshape deformer in Maya. I am doing this as many people asked me for my UV blendshape deformer.

In this tutorial I will show how to write a simple Python script that uses OpenMaya to set the positions of points from a mesh to match the UV coordinates of each point. As one vertex can have multiple UV coordinates (as many possible UV coordinates as faces connected to the vertex), I will be using only the first UV coordinate in this script.

Compression Deformer for Maya (C++ Plugin)

This plugin computes how much vertices' edges get compressed and then applies a belndshape target.
Creating a target modelled as a wrinkled version of the base mesh, it is possible to emulate the way wrinkles are produced when the skin compresses during deformation.

Advanced Spline Solver (medulla)

Maya is great in allowing people to connect nodes together and build amazing rigs.
Even though, I always thought that an integrated solution, providing an IK/FK system with twisting and bending would be great. Thus I came up with the idea of this solver which will feature:

> spline IK (shown in this video)
> stretch and squash (shown in this video)
> twist (shown in this video)
> adjustable twist center (shown in this video)
> multipoint twist
> end joint snap
> implicit two-joints matching FK/IK
> adjustable "elbow" binding

I'll soon post more videos showing other features...

SuperShaper - asymmetric blendShape plugin for Maya (C++ and Python)

I've enhanced the main algorithm for the SuperShaper. Now it is implemented in C++ and runs smoothly.
I've also added color feedback to better identify the splits.
Quite a big step forward compared to the first version I developed for the Ender's Game film.
In the video I show the plugin working on a simple face and also with a simple rig applied.

UV Blend Shape - Topology-independent blendshape for Maya(C++ Plugin)

This plugin comes quite handy when you want to transfer deformations between meshes with different topologies.
Imagine transferring blendshape targets between different characters or between two different levels of detail or when some small tweaks have to be made on top of a mesh, altering its topology. In all of these cases you'll want to have a tool like this :)

SuperShaper - asymmetric blendShape plugin for Maya (Python)

Hi, this the SuperShaper, a Python plugin for Maya I developed some months ago.
Whit this plugin you can apply blend shapes in an asymmetric fashion.

Rather than manually create splits of left, center and right side of a target shape, just drop the complete target in the SuperShaper and it will allow you to select where to split the shape and the weights you want to assign for each split.

I'm currently looking forward to a C++ implementation to make it faster and smoother so... stay tuned!

Medulla features development - skinweight propagation

Continuing the development of more features for Medulla. This is a key feature that will allow changes to preserve skin weights while changing the skeletal structure. It works by propagating the previous weights through the new bones (more bones or less bones, it doesn't matter).

 Use cases examples:
 - When you find out that you need more joints for a part of the body that you have already weighted
 - When you want to paint the weights on a simple skeleton and then convert it to a more complex one
 - When you have already weighted a complex rig but you want a simpler one for real-time purposes

Medulla - Rigging Toolset and Python API - first look

Currently working on a new Rigging API for Maya developed in Python: MEDULLA

Here you have a first video showing current status of development.
