Can I edit an avatar I bought on Booth?
Yes, that is exactly what LAS is built for. Import the base and any outfits made for it, and LAS sorts and wires everything so you can start editing right away.
Will editing break my avatar?
No. Edits are non destructive and your original files are never modified. You can also run your avatar in Try it, a live in-app test, before anything is uploaded.
Can I change colors without retexturing?
Yes. LAS recolors materials directly from a color wheel with a live preview, so most color changes never touch a texture file or an image editor.
Do I need to know Unity to edit an avatar?
No. LAS drives Unity and the VRChat SDK in the background and shows you a simple menu instead. If you do know Unity, LAS is still the faster loop for everyday edits.
