Short answer...Yes you can. Hopefully someone will find the previous post that explains in detail. In the meantime here are my shorthand notes on what folks said about the subject......Hope it makes sense and helps. It works for me.
" You need to locate the "iClone Templets/Presets" folder whereever you have installed iClone.
Create as many new folders as you want for your animation categories, just make sure each one has the 3 BMP files for its button. You probably want to make your own graphics. I did a quick test by copying the "Idle" folder and renaming it "IdleX". I then went into that folder and changed the names of the BMP files to:
IdleX_Click
IdleX_Def
IdleX_Over
Sure enough, I got a fifth button and had to use the arrow to move sideways in the category list. You do need all three!
The categories list alphabetically from left to right it looks like. My "IdleX" tucked in just to the right of the original "Idle".
Locate folder that has the anim you want to use with the "Find File" button in iClone.
Copy the iMotion file to your own folder in the iClone Templets/Presets folder. This folder should have the 3 .bmp files included.
(If it's an older .vns anim you need to load it to an Avatar then "Collect Clip" to create a new iMotion anim clip or just rename it with the .iMotion extension)
Once the iMotion file copied into the folder I locate an .ini file and copy it and then rename it to match the name of my new anim. For every anim file in your Preset folder should have an .ini file of the same name."
Maybe some clever, helpful person will write an app to do this automatically. It would be a HUGE help!!!!!
