[MaxScript]Subdivision Reversion

obliviboy

Subdivision Reversion will recreate the subdivision levels of an already subdivided mesh with 100% precision. It works with only 3ds Max 2011 and 3ds max 2012 (x86 and x64).

Here are some of the benefits you get:

•If a 3d model you buy online has it’s modifier stack collapsed it is almost useless, you can’t edit, unwrap, rig it, but with Subdivision Reversion you can reconstruct the first subdivision level and then do all the above.

•If in your production pipeline you need at some point to collapse the model with Subdivision Reversion you can get the subdivisions back later

•When you apply a turbosmooth modifier to a reconstructed subdivision level you will get exactly the same mesh as the original

no, turboreduce just was deleting the unnecessary edge loops, Subdivision Reversion recalculates the vertex position of the new mesh so that if you apply turbosmooth to it you will get the same high res mesh as the original one

I havent had a use for this yet but is there a way to set it up so the script doesnt move the new objects? It seems like thats an alignment issue waiting to happen.

So, you are saying that even the point order would be the same between the original highpoly, and a "re-turbosmoothed" mesh obtained after applying a regular subdivision algorythn to the mesh that your script spits out ?

If so - very cool !!!

I wonder if all apps create point orders the same way tho - it'd be interesting to verify the OBJ data from Maya, Max, Mudbox and Zbrush. I remember noticing that merely performing a convert from edit mesh to edit poly is enouh to screw up the point order in Max hehe

@AlecMoody I can make so it doesn't move, but now I prefer that it moves. If anybody wants it not to move I can make it for them.

pior no the point order doesn't remain, only the point positions.

making the position offset a user option would be best.

See the shape of things to come.

saw this a week ago on ScriptSpot, looks soo good! Costs though doesn't it?

reordering the points at a 2nd step shouldn't be a big deal.
But this is a really cool script!
