Hi all,

im sure this topic has been covered before but a search has brought up no results

Is there a quick way to invert an image map using material nodes?

Invert the colours or the orientation?  AFAIK, both can be done but I can't call it to mind right now.

I think you have the option to change the orientation in the Image_Map node itself.  

As for inverting the colours, I'd guess there's a way to do it with Math_Functions.

i meant inverting the imagemap,yea thats what i thought,but ive gone through them all to see if it would work but being a maths dunce it wasnt likely lol so i was hoping there would be one or two nodes id have to link up to get the desired effect

Invert colors:

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
