Скачать или смотреть Roll a Wheel Around using Simulation Zones in Blender Geometry Nodes

This is a walkthrough of a geometry node simulation setup that can be added to an object in order to simulate a rolling rotation based on the object's movement through the 3d space. To make this even more useful, it might be good to transfer the simulated rotation to a rig via constraints, rather than modifying the geo directly, I think that can easily be done with a little more setup, but I didn't cover it in this video.

I have made a number of tools for Blender:

DJH Geometry Node Assets
Since their addition to Blender I have been gradually making and incorporating procedural tools into my workflows. With the addition of the Asset Browser and Geometry Node Assets, --and mostly to end the endless pain of browsing and appending--I began organizing my best nodes into an asset collection. This project is the result of that effort and currently contains 65 modifiers/nodes that are generally aimed at reusability and versatility.

TerraNode - Node-Based Terrain Modifiers
When making terrain, I often want to place details where I find them important, but I usually do not want to take the time to sculpt every little mound and rivulet . . . To marry those two contradictory facts, I made the TerraNode modifiers.

Strands: A GeoNodes Library
Do you ever add ropes, chains, wires, or other long thin and flexible objects to your scenes? Strands is a GeoNode Asset Library, containing a set of modular modifiers to help you do exactly that. The modifiers assist with placing curves in your scene, appending additional details to them, and meshing those curves into ropes, braids, or chains.

Petrify: A GeoNodes Library
Petrify is a library of tools designed to help you make rocks. Whether you want a bunch of small rocks to scatter across your scene, a few large rocks to feature in a landscape, or one 'hero' rock to sculpt on, the Petrify library should have some tools that will help you.

Bake Batcher - Collection Based Baking
Because I got fed up with manually setting up each bake, editing dozens of settings, painstakingly selecting objects, baking each map separately, saving each image, and fifty other frustrations, I made DJH Bake Batcher. An addon that makes baking standard PBR assets feel more like pressing F12 to render a scene, and less like a marathon of details. Bake Batcher removes headaches by sacrificing the flexibility of customizing a ton of settings, for the speed and convenience of baking in a single click.
