Maya: Polygon Reduce Tips and Tricks

Posted by STLR, 20 August 2010 7:00 pm

Howdy folks...

Well I finally got an iPad and I have to admit.. this thing is pretty friggen cool.  I showed my 5 year old daughter some games on it when I first got it and she -loved- it.  She walked up to me first thing the next morning and said... "Daddy, can I play with your giant phone again?" :)

You may already be aware, but if not, Autodesk has 2 cool apps running on the iPad / iPhone, both of which are much more interesting when used on the larger screen of the iPad.

First there is -> SketchBook.  There are several youTube clips out there, but here is a quick demo movie of it in action...

Honestly this movie doesn't really do it justice.  For any of you artistically minded people out there that have ever carried around an actual paper sketchbook and pen/pencil... this lilttle app is for you.  It's perfect for roughing out an idea when you're away from your desk, or even just killing time in an airport.  Of course you still have to fork out several hundred $ for the iPad :)

There is also a little gadget app based on -> Fluids.  This one is more of a toy, but cool none the less.


So moving on to the original topic of the blog post.  A while ago I put together a short demo of tips and tricks for using Maya's Poly Reduce tool on hires meshes.  In the demo I show you how to reduce a character head from over 1,000,000 polygons to less than 2000.  Here'tis...

 

NOTE:  The audio and video are slightly out of sync.  Sorry about that... not sure what happened there.

thanks for that tricks steve... but most of the time we cant use automatic stuff here... we would need some retopo tools to have more control... take a look at the retopo tools from 3dcoat or topogun... that would be a great addition...

Yeah I agree it would be nice to have some similar re-topo tools directly in Maya. Maybe someday Although it's still a pretty manual and somewhat tedious process even with the help of these tools.

Ha... MAKw... are you a pirate? I never said it was new, although it was updated as recently as 2009. Just thought I'd show that the tool is actually better than its reputation. It's certainly not an end all be all, but it can be useful in certain situations if it's used the right way.

these videos you posted oglu look like turning a surface to "live" in maya.

Thanks for the tips on the transfer attr and poly reduce tools.

samann i know the "live" feature in maya... but with a decent retopo tool you are much faster...

Acctually for what it is .. this tutorial is great overview.. definalty suprised me in outcome and thanks for the tip on matching "volume" thru vert local space and then geting the uvs back!.. Was actually suprised. .thanks steve!.. ALSO COULD you do a FOLLOW UP with the PAINT REDUCE tool?!? Im thinking of something that has stepd detail in it.. kinda like a brain model or canyon... where youd want to reduce the plato parts but keep detail of caverns..

excellent I tried reduce tool ages ago got a lot of triangulation and gave up on it without looking into it - your tutorial has revealed my stupidity and given me a useful tool I was letting go to waste.
thanx......

Thanks for yet another practical and and useful tutorial. It is becoming more typical these days with the popularity of sculpting apps for an e.g. hero character game asset workflow to be high res sculpt to low res base, where the opposite was almost always what was done in the past. Some apps have a retopology toolset specifically designed to solve this problem, but it was nice to be reminded that Maya already has some powerful tools to accomplish the same basic task. With a normal map generated from that hi res mesh, that model would look great.
