Customizing the smoke from the cigarette

Select タバコ (さたにあ式タバコ) (Cigarette (Satania Tabako)) → タバコルート (Cigarette Root) → LipSync用 (For LipSync) → タバコの先端の位置 (Cigarette tip position) → タバコから出る煙 (Smoke from the cigarette).

Turn on Emission so you can see what it looks like.

I won't go into the details of the particle system here, but if you want to edit the material, change the Material under Renderer.

When you're done, turn Emission back off and that's it.

(If you don't, the smoke will show up for a split second when you switch avatars or reset your avatar, so watch out.)
