Normally it is no problem to change the particle-type of any emitter to e.g. a text or a picture. However, if I try this with one of the emitters from the 08_04 emitter library (e.g. the Logo and Text emitter), I can add my own text. But I can not get rid of the original PIllusion text. Are these emitters somehow locked? And when I buy the pro-emitters, are they also locked?
