I didn't work back on ioQuake since months, I've been busy with traditional art. So I can't help you with animation atm.
For the parallax / mtr shaders, you have your shader file and the shader (texture) name have the exact same spelling ! watch out for typing errors also. Make sure your Parallax-related Cvars are turned on !
As for the texture, I'm pretty sure I was doing something wrong with mine because I couldn't get rid of these weird deformations you can see on the screenshot.
I'm really busy on other things so I can't prepare a pk3 and test it out right now sorry ! But I'm sure You'll get it working after some time
