20. Extract Transformation Matrix

Another quick tip about extract transformation matrix in Houdini using "matchsize" and "extracttransform" nodes. This method is useful when you want to move animated object to world center, remove the animation and do your effects and then revert back the the animated version.

This is was insanely useful thank you for sharing. Now I can put off learning how matrix transformations work for a little bit longer.

Thank you man, you done my day

[@JafarDashti]

You're welcome!

Nice!

[@DaleBunten]

this was very helpful. Quick question, what if you want to sim at the origin using the rotation of the model and then restore that to the original animation?

[@JafarDashti]

Please check min 8:45 to the end, I guess this is what you can do. Matchsize removes the transform but everything else like roration and deformation remains the same. There is multiple way to deal with this transformations in general. You can also use vex and vops method but it's more complicated. There is some videos online easy to find for manual setup. Thanks!

What if you get a deformating mesh ( like cloth animation) ? Will this method still work?
Either way thanks for sharing

[@JafarDashti]

As mentioned in video you can use the second method if you want to keep deformation. just don't freeze the animation. this extract transform thing is all about moving your model to world center to have better control on stuff you wanna do and revert back to original position . thanks for watching
