Can I "freeze" vertex tweaks(pnts)?

[naughty]

If I create a new mesh object and inspect it's shape CV parameters they are all 0,0,0..

If I combine two objects together and delete the history, the new objects CVs are now 0,0,0

If I delete a face from a single object all it's CVs reset to 0,0,0...?

is there a way to reset an objects CVs tweak pnts back to 0,0,0... (without changing the mesh shape, obviously)?

I need to do this because I am writing a script which duplicates an object, then connects the inMesh and outMesh of the original to the duplicate.. However, any tweak values seem to be ADDED to the duplicate so it distorts out of shape. (I want them both to be the same shape)

Is there a way to reset the tweaks? or is there a way to ignore the tweaks when I connect the two meshes together?

the act of taking outmesh and inputting in inmesh collapses the tweaks. BUt your node does not restet the tweaks.

you dont actualy need to collapse the twaks all you need to do is reset them after youve connected.

this is relatively easy

heras a example that resets the tweaks for pCubeShape1.

{
$size=getAttr -s pCubeShape1.pnts;
$text="setAttr pCubeShape1.pnts[0:"+($size-1)+"]";
for($i=0;$i<$size;$i++){
$text=$text+" 0 0 0";
}
eval $text;
}

Tough ist not impossible to collapse the tweaks with mel. all you need to so is sum the pnts array with vrts array and input that into the vrts array and reset the pnts array.

What is the reaseon for you to duplicate the shape against creating a clean shape?

In reply to:What is the reason for you to duplicate the shape against creating a clean shape?

well, I want the new object to have all the attributes and shader assignments that the original has.. If I create a new mesh and connect the outMesh from the original, the new object has no materials on it..

Here's what I'm trying to achieve, maybe you can advise a better method:

I've taken the idea you (joojaa) posted a while back about a fixed projection map. I started with the same idea that you create a new mesh, connect it to an object, then projection map it. This allows you to move verts about and keep the projection static. This is a very useful tool that has been requested by several collegues, but I'm trying to re-write and refine this basic idea into a fully operational and useful tool.

The main difference I've had to implement is that the original materials and UV mapping must be fully preserved on non-selected faces.

I've easily mangaged to achieve this by duplicating the object instead of creating a new mesh (apart from the tweak problems I've mentioned).

so unless you know of a better approach I'll try the tweak reset you've suggested...

oh crap, I've just tried this and it seems my original tests were not quite thorough enough... connecting the outMesh and inMesh only seems to work when the object has a SINGLE shader connection...

I'm not sure how to progress now... is there any way I could connect the correct materials back to the duplicate/new object once I've connected the .out and .in mesh...?!?

I have no idea how material/face/groupId connections work...

I've just tried to manually assign a material to the selected faces of the duplicate (after connecting .outMesh -> .inMesh) and Maya gave me a fatal crash!!!
