Hi there,
I'm really not sure if this is even possible - but it might actually be really simple!
Here's the setup:
-
I've created an object which I've then turned into a component and copied many times to create a matrix of the same component. (To clarify, they are all copies of each other so whatever I do to one, does it to all the others)
-
I've created a very simple v-ray texture which consists of a "noise" diffuse layer using two colours; red and dark red. (so it creates a sort of simple "dappled" effect of red and dark red).
-
I've assigned that material to the component (which in turn has then copied across to all the other identical components)
The problem with this is that the material generates exactly the same on every copy of the component. So it doesn't look very good...
Short of making EVERY component individual (there's 100s of them) and the assigning it a slightly different material position, is there any way of setting the v-ray material to effectively generate itself in a different position on each component. Thus that the dappled effect doesn't just repeat itself in the same position over and over again? i.e. same component, same material, just randomly generated slightly differently on each component?!
Does that make sense?!
