Hi guys, I cannt use the unify function, for some reason, on the wave subtool. When I do it goes super tiny. It doesnt matter if I use transform/scale or deformation/size, when I hit unify it goes that size.
Thanks in advance for a hint.

it’s doing what it’s supposed to.
your dude is too big as well. use unify on him and then scale the wave to fit…
or scale the wave to fit, and placement, then use transpose master, make a T pose, unify that pose, then dump out the new t pose mesh, and all your tools are now the right size for Zbrush.
thanks for your reply goast666.

Thats how the two subtools gets when unified.
Sadly when using t. master and hit t. pose mesh it crashes.
I have read the t. master thread and I could be some overlapping polys but I couldnt find any.
is your dude “high” poly? that will crash Tposemaster most of the time. It’s meant for things with 1 or 2 subD’s that are lowpoly. anyway, you should be able to shrink your dude down to fit the wave now. 
Finally.
Yes, the dude was high res, you were right mate.
Using the resize in deformation I squeezed every sub part of the dude by using numbers and not the slider.
Then t-pose. Unify. T-pose=>sub-t.
Thanks again.

no prob, glad to help.
