Creature effects.

Thank you for the advice.
Could you please provide more details? I'm new to this. The editor is in advanced mode, and I was able to open the creature. I don't understand what to do next. There's a creature model with its arms outstretched and a sword nearby, but I can't do anything with it. On the right, I can only select the model's lighting; on the left, I can open it as materials, skeleton, geometry, or animations. In all four options, it looks exactly the same, but I can't do anything with the mouse. None of the buttons in the tools menu are active.
