I'm making a customizable character with switchable skin via driver. It is organized by 9 types of skin and each type with 3 make-up as you can see in the 1st image. A total of 27 images. So the driver property Skin range is 1-9 (bigger group) and MakeUp 1-3 (smaller groups). The problem is it isn't working. If a mute any 3 images, given me 24 images, it works. If I un-mute one of them going back to 25 images enabled, the shader became the magenta error.
So the question is:
Is there a limit for number of images in a material?
Is there a better way for me to do this? like a Toggle node or something like that. I guess a script node would be the way to go, but I have no idea how to do it.
