In the digital landscape, AI avatars have become the contemporary means of embodying our virtual selves. Eschewing the traditional customization process, you can now effortlessly describe your ideal avatar or upload a photo for instant 3D rendering. For smooth animations, ensure your avatar is rigged and converted into the VRM file format before venturing into VIVERSE!


The Best 3 AI Avatar Generators

To create a 3D avatar with your text prompt, sign up for an account to get 200 credits for free. Then, input your desired text on the left side and click “Generate”. Make sure to include "with T pose" at the end for proper rigging of the limbs. Select one of the four avatars generated. If you're unsatisfied with the quality, refine it using the “Refine” button.

You can also try out the other “Image to 3D” feature and see your avatar generated in about three to five minutes. Note that once the character is generated, adjustments can’t be made.

Navigate to the VIVERSE Avatar Creator and opt for the Realistic Avatar (Beta) feature. This free AI character maker turns your 2D selfie or portrait into a lively 3D character within a minute. Select your preferred base model, whether male or female, and ensure adequate lighting conditions. Remember to remove your glasses and refrain from smiling to keep your teeth hidden during the generation process. Alternatively, seamlessly initiate the transformation by uploading a photo. Wait for a minute, then you’ll get your rigged 3D avatar.

 Customize your clothes and accessories if you consider the default clothing too plain.

AI Avatar FAQs

To answer your frequently asked questions, such as how to rig and convert, and how to use your AI avatar in VIVERSE, we’ve gathered the answers below.

1. How to rig an AI generated avatar?

Step 1: Among the available tools, we'll use Mixamo as an example of 3D model rigging software for demonstration. Begin by creating a Mixamo account and uploading your avatar in FBX, OBJ, or ZIP file format.

Step 3: Review and check to see if you’re satisfied with the auto-rigged avatar. If you’d like to make adjustments, click on “Back” to change the markers or the skeleton LOD. If not, proceed by pressing “Next”.
