The following is a mix of summary of the presentation (not necessarily in the same order presented) and personal opinions and … More NVIDIA Omniverse and the SIGGRAPH 2023 Keynote
I created a scene using NVIDIA Omniverse standard assets. No movement in the trees or grass. Ideally want some wind to give the feeling of movement. Here is the final video. This is for the current Omniverse #StartToFinish community challenge. My process I wanted to animate models (trees, grass, bushes, etc) to get a bit … More Omniverse Start to Finish – Wind Animation
I was exploring how to display a USD model in a web browser. A few people had asked about streaming Omniverse output into a browser window, so I was curious to see what tools or approaches are possible. TL;DR: There is a WebAssembly port of the Pixar OpenUSD libraries, but it is large and the … More Displaying USD 3D Models in a Web Browser
I am trying to identify a good solution for dangling hair bounces and cloth (e.g., a skirt) in NVIDIA Omniverse for characters/avatars. The recently released Omniverse USD Composer (Kit 105) now uses “Omnijoint” intead of “SkelJoint” for skeleton bones in characters. These are real prims, so you can add children prims and they will track … More Omniverse 105 (beta) Colliders for Particle Mesh Hair and Clothes
In NVIDIA Omniverse (and OpenUSD in general), animation clips are tied to a specific set of skeletal bone names. This is fine if you create your own animation clips per character, but there are many libraries/stores of animation clips available, and they use different bone names in the animation clips.

NVIDIA Omniverse includes Audio2Face, an AI powered audio clip to facial animation tool. Give it a voice track, and it can animate the face of a character. It even has emotional expression support. Very nice! But how to use this tool as part of a pipeline to create a Pixar-like animated movie? In this blog … More Using Omniverse Audio2Face in Animated Film Production
I am trying to bring VRoid Studio characters into NVIDIA Omniverse. Omniverse has powerful deformers and particle cloth physics support which I am still exploring to get better movement out of clothes and hair, but they can interact strangely with each other and frequently I am just after some simple bounce bounce for hair a … More Implementing Springbones in Omniverse

I have found the Writing Excuses podcast (and archives) very useful to learn about the art of story writing. One I found particularly useful was episode 10.13 (“Where is my story going?“) on structure. (The episodes before and after it are all pretty good. Series 10 they started making the episodes more like teaching content.) … More Practical Tips for Structuring Stories
I have been working on getting a VRoid Studio character imported into NVIDIA Omniverse. VRoid Studio is free software by Pixiv for creating 3D avatars. You have less control than a product such as Character Creator from Reallusion, but the price is great! It can be useful to explore animation if you don’t have the … More First Steps for VRoid Studio characters in NVIDIA Omniverse
