I have modeled something in moi and imported to houdini and am having problems when trying to create liquid from this object. I have tried this with just a regular box that I made in houdini and it works fine.. I select the object, then the liquid container and then the box shows up as liquid in my renders.. however with anything else, such as something that I import it does not seem to be working..

so far I have tried adding a volume sop to the object but I don't know much about this so I'm not sure if I need to do something else since I know an object needs to have volume to apply the liquid from object.

I am kind of lost in regards to this so if anyone has any advice I would greatly appreciate it.
