In Development: Subdivide and Smooth

GUNAWAN W

oh dear God, please give this guy more power to made this script available to everyone soon.

Yummy !
Terrific results as far as I see.

This together with a 'wrap texture around object' feature could possibly make other 3d party organic model software trash can material.

Good stuff Whaat!

I wrote script below to simulate whaat's.It works,but not perfect

thanks wikii, nice script you've put together so quickly! here is a resulting surface for illustration. and your script with a plugins menu entry added to just place in the plugins folder

wikii's smooth surface script

It would be great if you could do a script that could make high poly models low poly. It would be awsome.

jenujacob

holy moly! this is simply terrrific!
how long did the sub division take coen?

erikB

amazing
Coen, would it also be possible to leave the 'knife -like features' on the claw as they where ( I mean not subdivised (and rasor scharp ) or is the whole model always subdivised ?

wow, i cant believe my eyes, this is going to be an awsome script to use!

Hi all,

I am looking for one more beta tester at the moment. I need someone with a lot of free time on their hands (anyone??) I am worried that the current testers are too busy to test and post bugs. Is there anyone out there who could commit to spending a LOT of time testing over the next week? First come first serve. Please respond right here.

Daniel S

Here!

chippwalters

I can help. I already sent you a private message yesterday about this. I'm currently doing a project which could benefit. Plus, I've experience in scripted solutions.

OK, you got the job! I expect a two page bug report on my desk tomorrow morning.
Seriously, though, please give as much feedback as you have time for. I will send you a PM later today. Thanks.

I'm sure a lot of people's projects could benefit. What I need is someone who has time to test and post bugs and feedback. If you are still interested I will send you a PM.

chippwalters

Yes. Still interested

I'm in, i have free time.

That is amazing to see what Coen has posted. This script is something special!

A preview using the latest SubD Beta. This is my first 'playing around' model. Couple of interesting workflow techniques. You can set up SubD so you only work on half of a model, and the proxy components are updated as fast as possible. You can update them with a fast and low SubD setting, then when you're finished, you can update the proxies with a higher SubD setting, as this picture shows.

Also, you can 'crease' edges and vertices, so you have more control over how tight the SubD patching is fitted. A very, very cool plugin which, after taking a bit of time to learn, will be most valuable in everyone's toolset!

The rendering is Podium overlayed with a line render from SU.

All together now, SWEET!

kwistenbiebel

That's cool stuff...So if I understand well, you can keep on modeling the low poly proxy and it will automatically update the rounded object right?

What would happen if the low poly object has textures applied?
Do they hold ?

@Whaat,
Great job man !
