Modeling, Animation in Maya, Effects in Houdini, Compositing in Shake

The original inspiration is this picture. I tried to make something… feminine.

The trail effect is a Houdini softbody.

And, custom x-ray shader.

The key idea of this shader is multiplying U or V to normal falloff and putting them to the different channel.

B channel : x-ray

R channel : x-ray * U

G channel : x-ray * V


Houdini provides an easy way to control particle color.
The particle color is connected to COP image, and I animated the image instead of making a complex expression.
