I can use Mix node, but it only supports 2 textures

Use Mix Shader or Mix Colors (it doesn’t much matter)

You just need to animate Fac from 0 to 1 or from 1 to 0 after replacing one of two textures. The point is to replace the “invisible” texture and animate the mix factor from the current texture to the new one.

Something like that https://v3d.net/q0m

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

Thanks for your reply, but I have more than 2 textures and I want to change textures in the runtime, for example, when animating mix from 0 to 1, texture01 will be covered by texture02 then I want to replace texture01 with texture03, so I can animate mix from 1 to 0 to show texture03.

BTW, I can’t use multiple mix nodes in Blender because I want to change and extend texture libs without re-exporting the glb file.

So, what’s the problem? Read Value, use logic and animate Valueaccording to its current state. If 0 – replace the second texture and animate Value from 0 to 1, else replace the first texture and animate Value from 1 to 0.

There’s no need in it. It’s possible to cycle through several textures using only one Mix node (in that demo I used a list of three textures).

yes, I can replace texture01 with texture03, but it looks like the texture01 in the replace texture node is not a variable， so I can‘t replace texture03 with texture05

Names of textures in your material won’t change. It will be always “texture01” and “texture02” after each replacing. Only image data is changed, names remain the same.
