How to add a non-repeating image to an object?

I don't have much experience in UV-mapping -- could someone perhaps link to a description of how you add two different non-repeating images to an object?

For example, add a black circle to the front of "Suzanne's" face, and a red circle to the back.

I assume I should use some of Octane's Projection. But I haven't had success with them yet (images still seem to repeat, though perhaps only twice).

You can achieve this using UVW Transform:

On the left material with shown node setup. On the right normal texture setup.

Thank you for your reply!

I'm sorry, but I don't understand how it applies to the 'Suzanne' situation -- e.g. I'm not sure what you are achieving with this setup?

However, I think I figured out how to place one non-repeating image on an object (as shown in the attached .blend and screenshot): By using the "White Color" option in the Octane Image Tex instead of Wrap around.

But I also tried this in another project where it did not work (the image was shown twice, instead of just once.)

And what I still can't figure out is how to place a second , different image on 'Suzanne'...

(I know this is a very basic question :oops: , and perhaps I should rather ask in one of the Blender communities; I'm just not sure if there are any Octane specific options I should be aware of.)

Sorry, I thought you wanted to achieve a non repetitive look of a texture.

If to want to combine two textures you can try Multiple texture like in the example below:

Super J.C -- thank you so much! Just what I needed!

I have literally thought about this for years! :)

To help textures positioning you can use Transform nodes or you can create maximum 3 UV sets (per object) and use them with any texture if you like.

Thank you very much again J.C, this is just so perfect!

(I copied the node-image and mailed it to myself, in case it would ever disappear from the forum... :mrgreen: )
