I have 3 normal textures for a mesh. One is the main one and the other 2 are expressions. I am trying to use a driver/s to use this textures when posing a bone.
My problem comes in that my knowledge with drivers is almost none. All I know is to use the var expression which I have used for posing correctives and also for interacting between 2 textures in the shader editor. But now I have 3 textures and I honestly can’t figure out how to setup the driver.
What I’m trying to do is have the main normal texture by deffault, and then move a bone lets say 1m +y direction to change to the second texture. But I will also like that if I move the bone to 1m -y, then the 3rd textures could be applied instead. And back to 1st texture when rest pose again. I hope it makes sense.
An easy (if crude) way to do it is to simply set second driver expression (in the second Mix Node) to “-var”.
Mix textures in the right order and you’ll have mix values as follows:
rest texture: Fac1 = 0, Fac2 = 0;
second texture: Fac1 > 0, Fac2 < 0 (which is outside of [0,1] range so it doesn’t do anything… i think);
third texture: Fac1 < 0 (ditto), Fac2 > 0.
Thanks a lot!
It did help. It was simpler than what I thought.
And thanks for the quick reply, it took less than 4 hours to get a solution. I’m used to wait at least 24 hours between replies XD
