Blend Shape Builder for Unity

It is a tool to create blend shape on Unity. In addition to synthesizing existing models, you can also edit vertices on Unity and blend shape it.
Also, it can generate special blend shape targets such as synthesis of only normals, only the vertex position, and has the function to write an existing blend shape as a separate mesh for each target.

Dual quaternion skinning for Unity

before and after

Unity‘s skinned mesh renderer applies linear-based bending, which can result in collapsed volumes and “candy wrapper” twisting in the limbs.

Dual-quaternion skinning is an alternative method that helps preserve the mesh volume. It’s slower than linear-based, and has its own minor artifacts such as a bulging around the joints, but is a big improvement on the collapsed joints.

Constantine Rudenko has created a compute shader and scripts to convert Unity’s skinned meshes to dual quaternion at runtime. Blendshapes are supported.

Adobe announces the end of Fuse CC

Ahh…, Fusette 2015. Nothing free lasts forever.

Adobe has announced the sign-off date for Mixamo’s figure creation software Fuse. It will be pulled from their Creative Cloud service at the end of summer, 2020.

in an official Adobe blog post, Mixamo’s own Jeanette Mathews announced:

“We have tried to keep Fuse available as long as possible, but, unfortunately, it will soon stop working on the newest Mac OS (10.15), once it releases later this year, due to incompatible technology components. You will continue to be able to use Fuse on older Mac operating systems or on Windows for the next year. Fuse will be removed from Creative Cloud and will no longer be available for download starting on September 13, 2020.”

Adobe acquired Mixamo in 2015, but were cagey about their 3D ambitions. At the time they announced that Fuse would be worked into a Photoshop plugin, but later revealed they wanted the Mixamo team for software that would become Adobe Dimension, a user-friendly 3D program for graphic designers. Fans of Mixamo were devastated as Adobe slowly unvealed changes to the online Auto-rigger that ended support for Unreal Engine and cut off older versions of Fuse from easy rigging and blendshapes.

Adobe recently acquired Allegorithmic creators of Substance, and have announced plans for an AR art tool. It’s interesting to note, the announcement suggests the Mixamo Auto-rigger will still be available, possibly in connection with their online marketplace.

Fuse will work without being connected to the Creative Cloud – as defiant users of Mixamo Fuse already know. The figures can be morphed and textured within the program and exported as OBJ, serving as a base mesh for workflows outside of Mixamo.
