Does anyone know of a tutorial or something that deals with good polygon structure? I've been working on a shirt for use in Poser on Victoria 3. I build the basic shirt in Blender, export it to Poser, and do a dynamic simulation to fit it. (Basically over the animation, I start with her flattened, at the end she is fully morph, and the shirt is conformed to her figure.) The shirt performs well up until then, but if I use it in any other simulations involving motion, the mesh tears at the sleeves and collar. These are the places where I have to use irregular polygons to connect more regular grids of polygons. I'm thinking that there might be a better way of making the polygon structure there so it will respond better to being deformed.

better use the original torso as a template for your t shirt then, so the vertexes are in the place were poser expects them.

I'm not sure if there are any specifically for Blender, but there probably are a million tutorials on making clothes for poser and some of them must address this issue. Try crossposting in the poser forum. Pictures of the mesh and the problem would help, too! That way we can make specific suggestions. You might also want to import some clothes that do work into blender and see how they differ from yours. Using the original torso as a template may not be such a hot idea, there could be copyright problems and the vertices just aren't where you need them to be a lot of the time.

I believe PhilC has tutorial for dynamic clothes on his site, but I don't know the URL.

I have read the tutorial. It's not a tutorial for modeling the clothes though, just for using Poser's cloth room for dynamic simulation. I did post this too to the Poser forum on PoserPros for ideas on clothing. No one has pointed out a tutorial, but I'm getting some advice. I have been looking around for tutorials for other applications. When I mean importing the torso, I mean that I would use it to build the clothes around- I wouldn't be lifting or copying the torso into my work. It would just be there as a 3D guide.

thats ok then

Poserfasion had some good tuts on making dynamic clothes.
Triangles if I remember correctly seemed to work better for the cloth room.

If poser fasion is still alive, check it out and see if the tips help.

However tearing as you described it may also be due to the dynamic settings in Poser. Its been quite some time sicne Ive used the cloth room so I cant remember which settigns can cause it. Crud I know thats no use to you. :-(

Maybe I can get some free time this weekend to check those settings.
