View Full Version : Silencer Modeling Problem

04 April 2008, 08:57 AM
Hey Folks!

I wanna model this silencer:

And, as you can see, it has a lot of small rounded holes. And thatīs my problem. How could I model that.

I tried doing booleans, but it didnīt work the way I wanted. Hereīs an example of what I modelled. As you can see...itīs not clean at all.

Just wanna know how to make those holes not using booleans.

Thanks a lot! ;)

Take a look on the pictures in this thread, they will help you to achieve the result your searching for.

why not make a transparansy map for those holes?
i find that it does take a little bit of editing with the trans on the mat.
but the effect should turn out nicely.

What you have is not that bad at all, but the cylinder (the big, main object) probably needs at least twice as many edges to be smooth enough to handle a boolean. I'd try to model only a part of the cylinder with one hole, and rotate/duplicate it to create the full object, then merge it all. XSI does a really good job with booleans compared to a lot of other applications.

You can use the rounded edges bump node to get an edge highlight instead of beveling, which should save a lot of time.

Personally I don't really like the example posted that wraps a flat object around a cylinder and uses SubD for smoothing. SubD just never looks right on certain things, and on the posted example you can see the polygon surface cave-in slightly in the places farthest from the hole. There is no way to fit that.
