Hasta La Motion!

Hey guys,
I have been trying to fill a human model with liquid. I just need one frame of mesh for my project but the problem is tat

1) wen i use fill object it doesn’t fill the whole model, it fills it in parts, no matter wat i do with the resolution(500) or number of particles(8000000) it stays tat way. I even tried decreasing the scale but then it doesn’t fill the object at all.

2)another thing i tried was to fill the object in Maya & then import it in Realflow & then create a mesh but then wat happens is it takes hell lot of a time to create the mesh & the created mesh in no way happens to fill the human body it bcums much larger than the model. which still can be handled to an extent if i get to create the mesh tat stays inside the model.

Please any kind of help wud be appreciated. I am trying to get the effect of the torch man from the fantastic 4. Suggestions welcomed.

Thanks.
Ashita
