Hi, guys,

I ran into cookie error again when trying to boolean a polygon using another geometry.

please refer to the images attached for the problematic result and the result I'm expecting.

can you help to take a look and advise me on how to solve this problem?

Thanks!

Can't look a the hip-file now, but I would take a look at the normals.

you can try fuse SOP before second input

Hi, tamti, I've added a fuse node before the 2nd input of the problematic cookie node, but this still doesn't solve the problem.

I've also tried some of the options of the fuse node, but still can't get the cookie node to produce the right result I want.

Can you help to take a look of the hip I uploaded above and advise me on how to get the cookie node works?

Thank you!

Hi, LFX,

here's the normal of the problematic cookie result.

Can you help to take a look of hip file?

Thank you!

Sry, but I don't get what are you after? The group you want to delete doesn't exist here, and you translate input B down, so there is no intersection with input A.

you are using difficult geometry for cookie, you have many indifidual closed objects, touching at some sides
it's usually better to use just one closed geometry for each input

what i've done here is simple foreach loop which will try to union all groups of the second input to get minimum number of closed geometries
then this cookie will behave more predictable

i've also slightly scaled first input geometry, because it is not for cookie if you are trying to cut along already existing edge (in your case boundaries)

Thanks, LFX and tamte!

after I scale the rectangular polygon to be booleaned, the cookie result is correct now.

I guess it's easy to get problematic cookie result when the edges of the polygons input into the cookie node are overlapping……
