Corona tension map!

I kindly request a small but maybe useful stuff for Corona.
A tension map to be used mainly for skin deformation rendering.
Imagine a surface gloss or reflectivity or anisotropy (in UV coord) that change using tension or contraction of a mesh like human skin does.
CoronaTensionMap must compare the current deformation of a mesh with a reference state and generate relative compression and expansion in form of a grayscale or color ramp.
That info could be usefull to modulate certain effects (skin).
Sorry if this is waaaay too specific implementation, but i loose nothing asking kindly. XD.

this is currently too specific to implement, maybe when we go deeper in VFX
