How to make fade effect for live2D model in Unity?
The SDK version is Cubism Four SDK for Unity R3；The Unity version is 2019.4.2f1；The render pipline is URP；
Thanks for reading:)
My game using live2d as NPC on dialogue, I want to make some effect for them(e.g Fade in when NPC appear, fade out when NPC leaving)
It is simple to make fade effect for live2d if I using RenderTexture to show live2d. You know, just controlling alpha of the rawImage. But using RenderTexture is kind of expensive on mobile, especially there are 3 or more live2d in the scene.
So I am trying to modify the opacity of live2d model directly. But the performace does not good.
I suggest the problem is caused by alpha blend. So how should I solve this problem, it is really important for my dialogue performace.
