I have problems with forearm

zeni1agent

I work in daz and zbrush 
I'm trying to draw a forearm but it doesn't work. I rotated the forearm bones 90 degrees so that all the muscles were straight. after I loaded the model into zbrush and started to deform it with straight muscles and after I want to load this model into daz
But there is a problem 
I can't return the forearm to its original position before loading the morph because there is no rig in the zbrush . And I can't do this with a brush because I don't know the exact strength of the rig's weights.
I pre-rotated the forearm 90 degrees on the model before loading the morph and when I load the morph it automatically deforms so I tried to load it with Reverse Deformation. Everything worked but now I need to use adjust rigging to shape to freeze the bones later. But when I use adjust rigging to shape the morph deforms. I tried memorize figure pose but it didn't work.

Sorry, maybe I didn't really understand, but what I got out of this is, that you want the forearm look like in your top image, when it is in that position.
Reverse Deformation seems the correct methode to me, but you will need to use your morph target as a Joint controlled Parameter (JCM).
You use your fore arme bone twist as a master and connect it witj the freeze command in the right click Parameter tab to your correcting morph.
Now save your morph as a Morph asset.
Right click> show in Property hirarchy.
In Controllers 1st Stage you will find the twist bone.
Click and drag your character morph into the 2nd stage.
Now your custom morph dials in every time your forearm twists, but ONLY with this one character.
Hope that helped.
