Designing an avatar that reads on stream

The avatar is usually seen at a small size in a corner, so prioritise a clear silhouette, a distinctive hair shape and one or two signature colours. Add an accessory that reads at any size (headphones, a ribbon, a floating companion). Describe the default outfit in full; alternate outfits can come later as edits or scenes. The anime style is the natural fit; cartoon and chibi suit mascot-like avatars.

Expression sets and panels

Render an expression sheet with six to eight faces on a plain background to decide how the avatar emotes. Then render stream assets: a "starting soon" scene, a "be right back" pose, a "stream ended" wave, a thumbnail pose with space for text. Square and 16:9 shapes cover most overlay slots. Clean quality is enough for overlays; Detailed for a banner you will upscale.

Alternate outfits

Use Edit on a finished render: "swap to a winter outfit with a scarf and coat", "formal suit version", "summer festival yukata". Each edit is saved as a new image, so you keep the whole wardrobe. Pin the ones you want future renders to respect, or make a separate character for a major redesign.

Clips for announcements

Animate a finished render for a debut teaser or schedule post: "waves and winks", "tilts head and smiles", "hair moves in the wind". A 5-second 1080p 9:16 clip works well for short-form announcements. Note that these are rendered video clips, not a rigged model; the sheet and expressions are what you pass to a rigger.

Briefing a rigger

A rigger needs the front view at a neutral expression, a side view, the hair shape from the back, and the expression sheet. The automatic turnaround covers the first three; render the expression sheet as a scene. Upscale the sheet to 4K so details are clear, and download everything as plain files. Note which colours are exact brand colours in your message. A clean sheet shortens the back-and-forth more than any other single thing.

If you are still choosing between two avatar directions, make both as separate characters and render the same three prompts for each: a neutral portrait, a happy full-body pose and a thumbnail pose with text space. Comparing identical prompts is the fairest way to pick, and the loser can be deleted in one click with all of its renders.
