Reality Factory

I have set the object to empty, then tried setting the object to empty and hollow, but the water entity will not let me change the 'model' it is attached to to anything. I am unsure why.

Create a solid brush, then select it and turn its type to Empty in the Brush Attributes dialog. Go to the Models tab on the command panel, click on Add Model (with the brush still selected) and enter a name fo the model. This will allow you to select the brush as model for the Liquid entity.

thanks
