(Bug) SubD problems

Dear Support Team,

I am facing an issue with the Reflect command when working with SubD. After applying Reflect, some faces disappear, and edge loops that were previously aligned with the reflect axis are also affected.

Additionally, I was wondering if there has been any progress on the ability to apply different materials to individual SubD faces, similar to how it works with polysurface faces.

Thank you in advance,

Jose

_setPt to prepare a 100% precise symmetry plane did not solve it.

i deleted all non-quad-faces and the huge wing-like quad.
→ reflect works.
_insertPoint to make all faces quads
still the huge wing-like quad causes reflect to fail.
did not find why.
_reflect without the huge wing-like quad
recreated the huge wing-like quad in reflect mode


there might be some hidden flaws - but I did not find them.
let s see what others comment / find…

happy modelling - kind regards - tom

Thank you Tom for having a look!
Unfortunately, being able to apply a reflect when needed is convenient and a natural practice with SubD modelling in other software.

I’ve tried to remove the reflect and reapply to your model and problem arises again.

I hope someone from Mcneel team could guide us better in order to solve this bug.

Cheers!

Thank you @Tom_P !
I hope McNeel can solve this bug (as well update the title of my topic accordingly, as I don’t have the option)

Also, just a reminder about the request to apply different materials by SubD face.

Thanks!

there is a small pencil icon below the title, you can edit it

Thank you @Guillermo_Varela !
Please, don’t forget about the material per SubD face feature.

Thanks!

I will add your comment to the existing issue: https://mcneel.myjetbrains.com/youtrack/issue/RH-56446

Dear @Guillermo_Varela .
Any progress in those 2 main topics?

Hi, no, I haven’t received any news from the developers yet.
I will let you know when there is news
