How can I simply rotate a texture or material 90 degrees on a model?

Simple. How do I rotate an image on a model???

thank you!!!

Jacky, I’m not getting anything from this…I plugged the 5,-5 in the 25. and I have a texture coordinate in the uv and the output into my texture. is that right??

Screenshot please!

If i disable the custom rotator and just plug in the texture coordinate it shows the same thing/

Rotation angle needs to be 0.25, not 25.

thank you!!! so much!!!
