View Full Version : Different SubD scheme... how?

I've already asked this somewhere else but I might get a bit more of a response here.

Is there anyway to get Maya to Subdivide using the Loop method(aka "Linear")?

These things are better explained by pictures. Create a SubD cylinder, now try and get the the traingles on the top to tesselate like the method on the right of this picture:

This is using Smooth Proxy set to Linear method. But how to get Mayas SubD's to do this?

Anyone?

I have never tried to do it but it should be very possible to get the result you are looking for by creating your subd geometry then inthe attribute editor change the teselation options. :shrug:

What tesselation options?

It gives me the choice of adaptive and uniform, but these do not change the tesselation type.

I haven't got a clue how you can do this, but I am very interested why you like the linear method better than the exponential. Surely those tri's don't look better when rendered, or do they?

Why is the second one better? It creates a lot of tris, the 1st one seems better to me. :shrug:

Uh..... it's kind of a dull story, but simply put it's for a realtime game engine. The way the engine handles the level of detail blending requires the second approach.

(yes, a game engine using SubDs... the future is here :)

go into your sub'd onjects attribute editor and see if there are tesselation options there...

I would be very surprised if you can do this though...

Sorry, I've tried all the obvious stuff, searched all the many attributes availalbe to SubD objects.... nothing :(

The programmer believes he might be able to do something about it during the export process, or failing that write his own SubD plugin for Maya..... :hmm:

Thanks anyway folks.

Smooth has a linear option, default is exponential. That might be what you are looking for.

Yeh, I know. But we need it in proper Sub-Ds, we need the creasing functions.
Linear in Smooth Proxy doesn't pay any attention to hard edges like the exponential method (default) does. Otherwise we'd happily use Smooth Proxy with Linear. :thumbsdow
