Material Expression Function Input can't choose TextureExternal

Hi there.

I tried to set TextureExternal with Input Type in Material Expression Function Input node but I can not select it.

It seems that they are shifted one by one from the Volume Texture.

I would like to put media texture RTT into my custom function node, but can not I still use it?

Is there any workaround?
Since my vide texture is large(4kx2k), I would like to use it directly if possible.

Reproduction is easy.

  1. Create NewMaterialFunction
  2. Put FuntionInput node
  3. Select Input Type Funtion Input TextureExternal

Type will be null.
