You're right, rendering is as long, but scene interaction is much faster
using instances. Plus, if the model changes they're much easier to update...
I'll probably use duplicates, however I'm still wondering why texture
UV's are evaluated only once when everything else is evaluated for each
instance... Oh well...
Thanks for the reply.

Any particular reason why you're using instances? The only situation
where I think instances are useful is for static, unchanging objects.
Even then, I now resort more on particle instances than instances.
They take long to save, and they have to be populated when you open
the scene.
It is my understanding that render-wise, instances won't save you
anything as well. Real geometry would allow you to do what you want.

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!
