When i create an expression in poser and goto the subset, all of the boxes are checked by default, it takes a million years to go through and Uncheck everything just to leave the few i want it to actually save. Anyway to make it clear all the boxes in one swoop? Thanks in advance!

The morph manager program can delete all morphs from an object. You might be able to edit the cr2 but that might be more difficult than deleting the parts seperately If you are not deleting all then I don`t think that there is an easy way.

If you are wanting to save a pose for M3 you can also use the DAZ Injection Pose Builder ($1.99 for PC members) on a saved CR2 to ceate an INJ pose; you just apply a pose that clears out the morph data but leaves the dial settings (speeds processing), save the character to your Figure library, then run IPB on the CR2. It's a fiddle in that you need to run a second program, but you don't have to worry about accidentally leaving out a morph you meant to include.

If you prime the slots in MM4 with a PZ2 (open any PZ2 and immediately replace with your CR2) you get better options. Anyway - open two copies of the figure CR2 in MM4. Delete all morph channels in one copy (there is a batch function) Copy in just the expression morphs and save. This is faster than deleting each of the others one-by-one. A pose file does not include settings for morph channels that the figure it was made from does not have.

Dont know if this works with parameters, but it works in other heirarchies, so might be worth a try. First collapse the entire Parameters branch by clicking the Minus (-) next to the word "Parameters". Once the branch is collapsed, UNcheck the box next to "Parameters". Re-expand the branch with the + symbol. Everything should now be unchecked and you can just select the ones you want.
