How do I create a LOD mesh? Is there a tool that reduces poly-count? How can I find out how many polys my mesh has? Do I simply build the lod mesh ontop of my orginal? Please help an XSI noob.

create a model and a lower res model then place it in your odf.

look at Kamino or Tatooine for refference.

thanks, but how do I know how many polys my mesh has?

Select the entire mesh (make sure you don't have any nulls selected) and press Shift+Enter. I think that's how you do it.

in xsi press shift+s and go to stats. then select show scene info and show selection info. Also another way of getting a LOD model in game is to select all geometry and go create>poly mesh>merge. name this new poly mesh something_lowrez. works every time for me

In XSI make the lowres object children of the original object and name it objectname_lowrez (where objectname should be the name of the parent object.

You also need to select the both models before exporting.

But what if the parent object is more than one mesh? Do you have to make a polymesh out of all of them?

The prop should be one polymesh, and it's lowrez should be another, and then, if you include collision primitives, those are each one polymesh to themselves.

This is a typical 3dmodel arangement for SWBF:



Note: for export you need to select all objects.

Rends

Well, you do that by baranch selecting DummyRoot, don't you?

It´s the shematic view ( 9 key)

Rends

No, no, I mean selecting all the objects, it's done by branch selecting DummyRoot.

Well no, you need to hold down the shift key and select everone.

Rends

lol - no Rends

t551 was talking about when exporting, and he's totally right you gotta Branch Select the DummyRoot, since EVERYTHING should be a Child of the DummyRoot

Well not sure what you mean with dummyroot.

Dummyroot is the parent null that everything goes under. Personally I call it MS3DSceneRoot, and it works fine for me.

Regarding to the screenie here:


I didn´t add a Null.
The Cube is the parent and everything else is a child of it.
So what do you mean?
Cube=Null=Dummy ???

And in explorer view if i select the cube only the cube will get highightet not the childs so i still need to select the childs one by one.
(Teach me if there is another way)

If the cube is the parent then you can middle-click on it to select everything else (branch-select), then export. I've never seen the actual mesh being the parent of everything though. Meh, if it works, it works.

Yeah, the way the dev's did it was to have, under Scene_Root, a null called DummyRoot, which has everything pertaining to the model as a child of it. When you export, you branch select (middle-click) DummyRoot, and then everything that is useful to the model is selected for export.

so....I don't need to reduce the poly count for a lod mesh? That's fishy...plus, my model is one object, so if I hit merge, my mouse has "pick" over it...couldn't I just duplicate my model and make it a lowrez?
