Problem when chamfering edges

Working on the handle of a weapon and I've run into a problem chamfering the sides. The polys on the right turn a grey/black colour and will mess up my render down the line. Can anyone help me? When turbo smoothed it looks even worse.

Hi Paradicia!

Do you have a reference image of what you are trying to achieve?

What is your background in modeling? Looking at that screenshot I would recommend doing some step-by-step tutorials on modeling, and trying to learn the basic consepts of subdivision modeling and topography.

Regarding chamfers and technical modelling, I deeply recommend this 40 dollar plugin from Marius Silaghi:

Your chamfers have probably got too big and overlapped.

If you're planning to turbosmooth that model you don't want lots of segments in the chamfers, you need to keep it simple and made of quads and let the turbosmooth handle the rounding. One segment for example, then smoothed will work much better.

As ebee says, look into some subdivision modeling tutorials for more info.

I agree with robinb's comment as the most likely cause of the problem, but a few other things to check on:

Before you chamfer, make sure you don't have any vertices sitting in the same place: select all the vertices of the mesh and send the merge vertices threshold to something like .01 or .001

It kind of looks like the new faces may just be in a different smoothing group. Try selecting all your faces and clicking "auto smooth" under the 'polygon: smoothing groups" rollout under the editable poly modify panel.

Good luck.
