cutted sculpts in 3dsmax

Hi I know how to cut sculpts in wings and make so separate objects appearing in SL but how to do that in Max ? to my experiments the same techniques do not work , and anyway when exports its less streight , is there another technique?

Do you mean pinching rings down to 1 dimensionality so they don't show up in the renderer?

If so, that depends on which sculptie authoring system you using in Max. SculptGenMax? Abu Nasu's shader? Chip Midnight's projection method?

Abu (Chip's technique is built on this) uses a surface approximation method, so you won't be able to get enough vertex accuracy to pull off the invisible prim ring trick. SculptGenMax is the thing to use if you want to be a prim illusionist. It's part of the Prim Composer system for Max http://liferain.com/downloads/primcomposer/

The renderer skips all colinear polygons (that are a line and not a face).
3dsmax coordinate system is "different" and the exporter may give a lot of rounding inaccuracy.
You can export sculptmap and then re-import and fix all rounding errors there.

anyways, does 3dsmax have a "snap all vertexes to grid" functions?
thats soo essential!

Max has some of the best snap options I've used in a 2d or 3d application. Also, unlike some other 3d applications Max has more than one way of exporting sculptie maps. That's why it's important to figure out what scheme the OP is using to generate maps. He could merely be using a tool unsuited to the job at hand.

So, Just to clarify, Max can easily handle creating collinear polys. I've done it plenty of times with no fuss or need to import back in and adjust as Ollj suggests. It's a matter of figuring which tools you are trying to do it with. Again - if you are using one of the surface approximation methods, that scheme isn't suited for the task. That's because of the method, nothing intrinsic to Max. If you are using SculptGenMax and getting errors thats likely because you left Truecolor on or have issues that will require more info to troubleshoot.

Blender has multiple methods and I'd be surprised if the same wasn't true of others as well.

Really? I've only seen your vertex based scripts. Do you have a link to the other one(s)?

Edit: Never mind, I found a shadier surface approximation method http://amandalevitsky.googlepages.com/sculptedprims

I added "some" in the post above. Everybody happy?
