As you already mentioned, you can tweak shader settings by using Object Info and Particle Info nodes. But that wouldn't separate shaders, that will just evaluate same shader differently for different instances.</div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jun 18, 2015 at 4:06 PM, Mohamed Sakr <span dir="ltr"><<a href="mailto:3dsakr@gmail.com" target="_blank">3dsakr@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">ok Sergey, I understand the part of object instancing, but what confuses me is: how does each object got its own shader?<br>I see inside Blender there is an Object info node, which uses data dynamically like Object index & Material index, is this the only way to separate shaders between instances?</div><div><div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jun 18, 2015 at 3:52 PM, Sergey Sharybin <span dir="ltr"><<a href="mailto:sergey.vfx@gmail.com" target="_blank">sergey.vfx@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">In your example is rather correct, it'll create two objects which are sharing the same mesh.
