that's the one. It also illustrates quite well the thing with the bevel
edges not shading correctly.

Here's a little something I put together a while back

It might help explain what's happening.

assuming the faces of the cubes are flat, your vertexnormals aren't correct
for flat faced cubes and none of the cubes are correct. You've added bevels
or rounding to the edges of the cube but haven't born in mind that the
normal calculator is going to average the normals between the bevels and the
larger faces of the cube. It's a common mistake. Select all the large faces,
duplicate and scale down very slightly.

Subject: [Rendering] Reflection behavior
hi everyone.
there is something that i didn't understood with reflection behavior.
If you look to the picture, if you see the 3 cube on the left , you can see
the reflection "tiled" but if you get the same surface but on the same
object the reflection "looks" more acurate.
It's me or it's normal ? if i observe around me, the right cube looks
better.
I guess i have to deal with passes to get what i want. but if there is
another way to do it..... tell me.
Thanks Harry.
