I'm experimenting with booleans in Houdini 16, I am trying with the simple scene I show in the image. I set the boolean to “solid” and “union”, output A-B seams edge group, everything fine. Now I'm trying to create a fillet between the two meshes using polybevel, but it seems that offset parameter doesn't work, it just extends the fillet a bit and then stops, the maximum extension is the one in the image.
What am I doing wrong ?
Thank you

Ray

Yeah, the new polybevel isn't really powerfull at all when he hit an intersection that's a bummer…

I just hit this last night and though I had been doing something wrong. It gets to a certain distance and then stops.

It seems that with the old polybevel node it works, not a nice result, but it works

You cannot expect to bevel beyond the ring of polygons incident to edges being bevelled. PolyBevel doesn't check for passing beyond those but it does check for internal collapses that are often related to those limits. With the number of columns on your tubes there's very little room left for bevelling. This is not even a Houdini limitation, no tool out there bevels beyond the immediate ring of polygons. Doing that would easily as difficult of the boolean if not harder. Your old PolyBevel result should also be broken if you inspect it over the top of the lower tube in the picture. You should find some inverted faces there.

Hi Ray,
On orbolt there is a free tool called “mesh blend” it looks similar to the fusion hda from vux.

nicoM, nice tool! But it looks like it doesn't fuse the seams between fillets and source surface. Is it true or am I mistaken?

Hi vux - it it is not my tool. But I think you are right … it doesn't fuse the seams.

Thank you nicoM, someone already posted it on discord but I found it a bit complicated. I'll try to use it again
Here is the post they sent me about the hda

You cannot expect to bevel beyond the ring of polygons incident to edges being bevelled.

This is a bit of strange thing to write tbh - other programmers have said you can't make a boolean that you did write in Houdini. Surely you need to do more R&D to try to overcome the limitation instead of saying your expectations are too high.
