Multiple Wire Objects with Wire Glue Constraints

Recommended Posts

Hi Guys,

I am doing some RnD on Tree Sim but running into issues in wire solver which has multiple wire objects and wire glue constraints, everything is fine up till 2 levels i.e bigBranches and subBranches but the moment I bring in twigs and subTwigs the constraints go crazy.

Can't figure it out what is causing this problem, can anyone help me out in this regard ?

Attaching a simplified hip file and curves bgeo for the same. 

Would really appreciate if you guys can have a look at it.

Best

Karan

if you predefined in wrangle  i@gluetoanimation = 1;
or different attributes that wire solver recognize ...

with different groups your splines and  assign orient attribute I think it gonna be smooth ..I can't open you scene Slowww and we need someone who know this ..I just Have FUn:wub:
Hope it Helps!

If you see my hip file I have used points groups and in wire solver then called in those groups in the wire glue constraint,I haven't defined any attrb in sops but still everything is smooth till sub branch level, but beyond that it starts complaining.

Hi @karanjaura,
Your scene is pretty much realtime for me, don't listen to that guy, he just spams with answers not bothering with the correctness of those.
You need to sort the points properly which is hard to do with the old wire tool. You have to consider using the vellum tool instead, it's the modern approach.

@Deviner I was hoping there must be some way to do this in wire solver :( , seems like I need to do this RnD in vellum now.
