Won't calculate on an object

Post by stellarstudios » 22 Mar 2017, 22:25

I am trying to use a model to be the emitter but every time I go to calculate, TFD keeps turning my model into vertices view and won't calculate on it. However, it will calculate on the teeth, left and right wings. Can not figure out for the life of me why! Any others have this issue? If so, did you get it resolved? Attached a shot of my hierarchy.

Do you have "include children" selected on the "general" tab in the "fluid emitters" window?
If so, try making a null and parent all of your objects to that, then make the null the emitter and again ensure "include children" is selected.

Also, double check that your surfaces are not 2d planes. TFD needs an object to have at least three dimensions. For example, if the object you want to be an emitter has height, width but no depth it can't be used as an emitter.
