3ds Max Skin Modifier Problem

SmilingMountain

Ok so I'm having a weird issue with Skin in 3ds Max. I have to create a character rig for the UT3 Ironguard for an assignment. However I've hit a snag when trying to skin.

When I add bones to the mesh, they are weighted at 100% to every vertex in the mesh. Weights cannot be modified using the weight table weight paints or any of the other tools. I have been through the advanced parameters roll out and can't see anything that might cause this. I am assuming it is something to do with the mesh itself, or perhaps the bones?

In any case I would be very grateful for any ideas.

Ok guys so a quick update. I exported the mesh as an obj and imported it back into max and now skin seems to be working fine. Seems my thought about it being something to do with the model was right after all.

UPDATE: Ok so now it works but only if I create new bones from scratch and skin them to the imported model. If I try to skin my pre-created rig to the model the same issue occurs.

Mrfred

is rigid vertex checked? what is the bone count limit ?

SmilingMountain

Bone effect limit is set to 20, rigid vertex along with all the tick boxes under weight properties are greyed out.

I've found out what the problem is, and found a sort of workaround. Turns out that when I applied the skin "normalize" was turned on by default. I realized this when looking at the weights table. "N" was ticked for each vert. However weirdly the normalize tickbox in the modifier panel is greyed out so I cant change it. Instead I've selected all of the verts in the weight table and manually unticked Normalize. This solves the problem but does mean I have to apply all of the weights from scratch. What I would be interested to know is A, why it has applied normalize by default, and B, why the tick box is greyed out. :poly127:

thank you you helped me a lot, it is common problem in max that nobody seems to understand.

Autodesk recommends using reset xref but didnt find it very usefull. it would be nice if you could reset model to  starting position.
