Title: rotation problem
Post by: atomov on May 15, 2020, 08:50:37 AM

Hi,

I'm trying to make a 2S array of cylinders and to have each one rotate randomly around pivot. What I'm getting is that when I rotate segments using transform node's random transformation from 0 to 360 segments also move randomly on X and Y. I need them to remain in place, just rotate locally. I've tried it on a linear array and it does the same, why is it doing this?

Hi
Problem is usually due bounding box for cylindric.
Try to set fixed size box to cylinders diameter but without "Scale Segment" checked then add a new transform operator with X/Y Alignment set to Pivot and Random Z rotation.

Here is the file
For RC4 it is better to use fixed-size parameters+Random numeric usually set to Segment mode because Random Transforms are cumulative and can cause some unexpected behavior unless you know what are you doing :D

Hvala Dragane,

This is a fantastic tip. I've noticed that when rotated 45 degrees on Z it looks like bounding box is affecting it but i didn't think of this solution. This is because of new stacking transforms in version 4? I'm sure I did this before with linear arrays but I never had this problem. Thank you very much!

Glad to help.
