I THINK THIS WORKS Assuming that the eyes are props, and are parented to the body, this is how you could do it. Load your pose file into a text editor, search for the name of your prop. e.g. if the prop is called "box_1" search for "box_1". You should see these lines: prop box_1:2 { channels { Now insert the following text: propagatingScale scale { { static 0 k 0 3.4 } interpStyleLocked 0 } And resave the file. The line that says "k 0 3.4" defines the scale, the decimal point is in a different place than how it appears on the dial, but "k 0 3.4" =340%. Hope this helps.
