Issue with Polybevel divisions causing crash

Hi,

not sure if this is a bug or I'm doing something wrong.

I have a curve that I'm insetting, then extruding that inset. I then polybevel the object. As soon as I increase the number of divisions Houdini crashes.

If I look closely at the inner corners of the objects bevel(before I increase divisions) I see a weird overlap of polygons.

I took a labs simple shapes and used a quad with exactly the same steps and there is no crash and no overlap at the inner corner.

I thought it might be because of the extra triangles so after the inset I dissolved the inside edges to see if that was problem but the same thing occurs.(see image)



What am I doing wrong ?

Thanks.

You have overlaping points after the dissolve, and then you are beveling edges created with those points after the extrude.

The reason they are not deleted with your dissolve is that you included them in the unshared edges group and then on dissolve you used 'Dissolve Non-Selected'.

Simple fix is just to put Fuse after the Dissolve

Hi,

thanks for looking at it. The I ended up putting a fuse after the extrude which fixed the problem in the what I assume is the same way as you suggest.

The fact that it caused a crash made me send a crash report and I got a response, the crash might have something to do with my preferences. Just not had a chance to try the fix yet(which is delete pref folder).

Thanks again.
