Modo edge bevel issue (workaround)

repete

Modo's edge bevel tool is a pain on low poly objects. It has been debated for years and Lux have simply ignored it which is a shame because I doubt that it will ever get fixed. Maya has nailed it btw !

The problem is edges that connect at 45 degree angles creates a mess:



Solution A increases the tri count and we want to avoid this as we are already increasing the tri count by adding more geo !!!

Solution one is the quickest way and many modo users do it:



remove all but one 45 degree edge on both sides:



This gives us 800 tris on this box:




Solution B requires more steps (4) but with a few scripts from Seneca the process is faster (Delete Half & Quick Mirror). The tri count is lower which is what we want:



Cut the mesh in half and delete the bad half and mirror the good half:



Add the 45 degree edge on both sides and remove the middle loops:



The result is almost the same with 96 tris less:




All done :poly121:

I would need to check this one out,

Do you care to post your unbeveled file so we look from scratch and see for ourselves with the same geometry. I think there's a couple of bevel scripts out there for Modo so you wouldn't have to use the factory default.

Yeah, I'm a bit confused with what you're beveling to start with here.

As far as I know, the main issue with MODO's bevel is that it doesn't keep parallel edges at corners.

A simple box with a hole it it:

What exact steps did you take to get the broken result in your very first image? Because you can get "solution one" results in one bevel (every edge), and the 704 tri result in two bevels (bevel the outer 12 edges then the inner 12 — no need to hope your object is symmetrical so you can copy/mirror it (though that's often a good way to save time repairing your mesh when something breaks).

To be honest I've no idea how you got such a broken bevel but it seems like an order of operations problem rather than the bevel tool's fault.

Your right Bek :poly121:

a tool reset solved the disappearing corners

Thanks

What kind of bevel does Maya produce?

Maya's bevel tool ignores the 45 degree edges:

Yes, i see now this is true, why would Modo screw up with such of a simple operation and give you uneven angles.

repete

You can get around this by removing the edges that run off at 45 degrees before the bevel:




but it does not work in every modelling situation

hhmm, i run "B" bevel almost in every operation i do, i always thought it was my fault. I know there's probably a few bevel script out there, can anyone try and fix this. Would be nice to have a bevel like in Maya.

here is a way to select the problem edges:




Select / Sharp

and there we are, this is what maya is doing (me thinks) before it bevels:

Farfarer

What MODO does is... the length of the new edges from the bevel are of uniform length, but that means the knees at an angle wind up bit keeping the parallel edges parallel.

Maya corrects for that, so the beveled edges might not be the length you specified the bevel to be, but keep things parallel.

Is there a simple solution for this? We tried it in 3d Max and it's the same but still a damning issue.

Solution C

just use Maya.
