Thanks for the reply... I'm not sure if it would work in my case though. Seems like the switcher has only 16 inputs, where I've got about 500 instances. Plus, my texture doesn't repeat, it's one big texture covering the entire instance formation. So I don't think it would work, or maybe I'm misunderstanding your idea...?

What's weird is that all shaders (for example phong or lambert, or reflection or even dirtmap) will be evaluated for each instance, while texture maps are only evaluated for the master model. Why is that?

probably not instances,
but i imagine with the ba colourswitcher shader set to random you ought to be able to offest the image uv remap parameters.


just make your uvs the size of one repeat (on your image) then offset by integers and you should be able to do it cleanly.

there may be a cleaner way?

Hi,

Let's say I've got a big object made up of little cubes. Is there any way the cubes can be instances, yet they would grab a different part of a big texture that is projected on the whole big object? I can't seem to find a way to do this, even if the texture support is outside the model that was instanced. Shouldn't it be possible?

Thanks!
