[blenderhelp6] Hello, i’m stuck here… i want to rotate each instance RANDOMLY along its Z-axis, to have more variety. But i can’t figure out what node to use… any ideas? thx!

For anyone reading this thread who don’t know what that video is since a link wasn’t shared, here is the solution: [image] (Use the Rotate Euler node in Local mode)

Hi, [image] Geometry Nodes: How to rotate Instances by its Z-axis with Normals? Modeling [ezgif-2-129740c304] Currently, the Instances can rotate via properly via its X and Y-axis. I’m curious if it’s possible to make instances rotate by its Z-axis with Normals. Normals …

Thanks for your reply, but thats not what i need. i want to rotate each instance along their individual Z-axis randomly, but KEEP their orientation along the sphere’s normals.

Here’s what I just also found: [Blender 3.0 - How to randomly rotate on one axis using Geometry Nodes] And here: https://blender.stackexchange.com/questions/216376/geometry-nodes-how-to-randomise-rotation-around-just-one-axis Hope it helps you

thanks but this only works on a plane. i want to do exactly this on a sphere, where my instances are aligned along the sphere’s normal vectors. and i want to rotate each instance along its OWN z-axis without changing the normal-orientation.

Try to find something similar on youtube. Maybe it would help you. Just google 'blender rotate instances sphere’ or something like that. I ended up with this one: [Blender tutorial - Geometry nodes - rotating and randomizing instances]

Thanks! It wasn’t exactly what i needed but it pointed to another video where the solution was in :-)) i needed to capture the vector attribute and point it to an Euler to vector, now i have exactly what i need!

You’re welcome Happy blending!
