I think I'm doing something wrong. I am trying to work with a wooden table, and some props. All items, including the table are in the props folder. I turned on collision detection for the table and all items I am wanting to place on the table. However, things still fall through the table instead of stopping at the table top. Is there something special I need to do other than to turn on collision detection for both the table and item I want to place on it?

You need to turn on collision detection for the whole scene as well.

For the whole scene? How do I do that?

In Poser 5, it's the lowest icon in the icon group at the top right side of the document window. In Poser 6, it's the triangle pointing to the right on the far right side of the document window menu bar (just below the close icon)

Ok, that's the button I used. There are 3 choices... Collision on, collision off, and one other thing which I can't remember. I set it to "On" for both the table and the prop... yet the prop still goes through the table. I have Poser 5.

I've had that happen before. The collision detection algorithm tends to get wonky if the polygon sizes of the collliding objects are getting vastly different. If the table surface is made from a simple scaled cube with only 6 polygons, you can be almost certain that the detection algorithm will fail.

I'm still working on a "drop to surface" Python script. Not ready yet. But I'm afraid it's the only way to go right now.

Just got an idea for a workaround using the cloth room. You might try converting your prop to dynamic cloth, select a few vertices on the bottom of the prop as dynamic group and the rest as rigid decorated. Place it shortly above the table, set all collision options and let it fall down... Edited to add: Just tested this idea with a simple box as the collision object and a hires ball as the cloth object. Only the lowest vertex was set as dynamic group, the rest was set as rigid decorated. Works perfectly - and fast too, since the simulator only has to calculate one vertex!

If it is the vertice issue you could put down a tablecloth of the hi-res square or even just flat as a big table mat.

I am using the items from April Follies which I found through Mystic Nights halloween treasure hunt. They're really great looking props. I just can't seem to get the collision detection to work. I've never tried using it before and thought I was doing something wrong, and am still not sure if it's me or if it's something with the props.
