Vertex Point Order Issue

[karanjaura]

Hi Guys !!

I am running in this issue where I want fix hundreds these frames thru polyExtrude ,polyBridge and polyFill inside a for each loop, but the problem is there vertex point order doesn't match hence my for each loop is failing and giving me a weird mesh.

How can I freeze or fix the point order so it remains same for all these frames ? I tried the sort sop inside the loop but no luck.

Would really appreciate if anyone can give me some advice on this.

Cheers

Hi,

it's hart to tell without a scene, try two sort sops consequentially inside for-each loop:

1. sort primitives by Y axis or others axes

2. sort points by vertex order

and see what will happen.

Hi @vicvvsh

I tired what you said but still no luck,I also tired copying the rest position of 1 frame on to others but that too is not working.

I attached below the hip file and bgeo . Would really appreciate if you can have a look at it.

you can use Match Topology SOP to try to sort points/prims of one geo using another as a template

Instead of poly extrude, you could try to use some work around using the "Skin" SOP, together with some copy/transform logic
that way you inherently maintain the point ordering.

thanks a lot @anim for preparing that hip file, it works  !!

Cheers !!

Hey @acey195 thanks a lot for your reply, will try that out as well

personally, I avoid PolyBridge like the plague...matching up the Source and Destination is in the laps of the gods....
