Astra has a full-featured layered decal system with complete tint and blend layers supported, making makeup systems trivial. Automatically bakes back to a single layer.

Poke-through Handling
Poke-through handling

Automatic skin hiding of assets based on cloth or hair above it. Optionally remove the fully occluded polygons for better performance on difficult hardware like mobile.


Fully deform your avatars through bones, materials, and mesh manipulation. Run-time projection allows you to only need to create shapes for your characters and not create follower shapes for your clothing.

Frequently asked questions

What platforms are supported?

Windows x64, Linux x64, MacOS x64,arm64, iOS arm64, Android arm64.

Can I create my own content?

You can create clothing, hair, decals, morphables, and more using the content creation tool. For figure creation, please contact Tafi.

How does streaming work?

Assets in Astra can be streamed, over a network, on-demand upon request in real-time. No assets are necessary to ship with your build allowing significantly reduced build sizes and quicker first-time-to-boot. Assets can also be pre-fetched and distributed with your builds.

What type of body shaping is supported?

Shapes on the avatars are split into mesh, material, and rig targets. You can create your own body shapes that mix and match these features allowing a large variety of effects from simple nose shapes to more advanced complete makeovers like zombies or aliens.

Do we need to adjust clothing and hair for each shape?

No, Astra automatically creates these shapes for you at run-time. Corrective shapes can be made if you want an exact representation of the asset.

Which render pipelines are supported?

Built-in, HDRP, and SRP are all supported.
