Thanks.
Yes obviously I did not want to model it onto the object. But I use Octane and checked out your videos and I know that I can move/reposition an texture/logo inside Octane but sometimes it is a bit tricky to get the result I want (size/position/proportions) etc... Maybe I thought it would be easier to make it with UV or something. But yes, if there is no other solution. I'll try that with Octane Render
