Title: XSplineMatID - how to include both Corners
Post by: Dragan on January 11, 2019, 02:56:42 PM

Hi Rokas,

How to set expression to return MatID for both Corners (Before and After segment)?

Thank you.

There are a lot of going on in Your scene. I am a bit lost in it.
Maybe there is a matter not only of expression but style/geometry itself.
Could You create a simpler scene with clearer expected final result.

Sure

I need  cylinder on both corners on spline ID3

tnx

from Your situation it seems like it has to be just number "3".
and something else has to be done to prevent it's effect in other places.

Since this is just a part of more complex generator it will be great to have expression Attribute that combine XSplineMatID and XSplineNextMadID so both corner vertex can be included/excluded.
Thank You for reply.

Is this what You are after:

return if(XSplineMatID==3 | XSplineNextMatID==3,3,1);

Yes Rokas, thank you, but that solution force me to track all potential ID separation. Imagine complex Spline with 35+ spline IDs.
If I go with logic that certain spline ID will carry some Geometry that  includes/excludes both border corners, expression Attribute that include/exclude those corners will be very helpful (no need for If expression...).
Hope you understand and it make any sense.

Best regards
Dragan

Isn't that what You have asked in the first post?
I am a bit lost.

Yes, Rokas

Solution is great, I`m talking about adding a new Expression Attribute as ER.

Sorry for misunderstanding  ;)
