View Full Version : keep edges when smoothing?

hey!!:wavey:

is there any way to set poly edges to make a crease when smoothing?
like you can when using sub-div's?

the problem i'm having is that when i smooth my poly's i lose all the hard creases, what is the work around for this?

my workflow:
1.model using CPS to get idea of what it will look like when smoothed.
2.delete smooth proxy
3. convert poly's to sub-d's
4.insert creases where i want them with "full edge crease"
5 convert sub-d's to poly's(so that creases stay but model is smoothed.)
6 harded normals where the creases are.


as you can see, it's a pretty long process to get the result that i want. is there a quicker way around this or am i missing something?

it would be so much easier to be able to select an edge on the low-poly cage and just make it unsmoothable, and also keep the hard normals.

any one have any ideas?

you can turn on keep hard edges on the smooth optin box. this way where you have hard edges, there will be some crease, but i found this a bad way if i want to do creases. the thing is that maya lets the entire edge untouched and it doesn't smooths in any directions, so you will get a strange result. :(

i found two good ways instead of keep hard edges turned on.

1. select the edges where you want the creases to be. do a bevel edge operation with low values. after this edit the beveled edges, where the new surfeces messed up! maya's bevel tool is a little bad when you use it for complex geometry :( after this, apply the smooth and you finish.

2. i like to use this one. split the polygons next to the edges wher you want the crease, move te vertices a bit, then apply the smooth.

hope theese things helped you.

hey!!:wavey:

thanks for the reply neonguy.
thats the technique i was using before i thought of converting to sub-d's to do the creases .
it doesn.t really give me a crisp enough edge some of the times.
also it can be a waste of poly's.
i suppose i could try just smoothing selected poly's and trying to "work around" the edges so to speak. dunno if that will work tho.

thanks again for the reply.

okay, as you wish ... but i think that if you want to smooth only part of the geometry and work later on the edges you get a little noizy mesh when you render it :(


oh ... and another thing. do 2 split rows instead of one. try that, it helped me in some cases.
