Great! Now I'm waiting for video where some octopus turns in to flying spider, then flying spider turns into walking unicorn. You know, rigging video can't go without that:)
Ok now seriously
1: is it possible to get it into Canvas, now. Last your answer I sow is from November.
It is now possible to create solvers in Canvas, and for those solvers to be called upon from Kraken yes. We have a separate UI for building rigs from Canvas.
2. more general question (and forget me if I missed the point) -let's say I want to build the deformation system directly in FE - is it Kraken who outputs arrays of matrices (or something like) - or it's my part to build the connection.
Kraken will build the entire rig in your DCC. Canvas solvers will drive objects like nulls or joints for you to then use standard deformation techniques from there. However we are going to be investigating how to streamline the solvers and graph so that you can possibly have solvers feeding other solvers transforms and such so that if you did have a system that was deforming geometry based on transforms being fed in, this would be possible too.
