I know how to create reflections but I don’t know how to make them perfect reflections of the objects and environment around them.
Does anyone have a link for a good tutorial about mirror-like reflections?
thanx.
2.3 guide will soon be published…
well, you can make perfect reflections only for planes and spheres
For spheres the EnvMap reference Empty must be in the Sphere Center
For Planes the EnvMap reference Empty must be in the specular position of the camera with respect to the Mirror Plane.
THis means Camera->(0,0,z) and mirror plane horizontal at quote z=0) as a see or lake or whatever, then empty in (0,0,-z)

"well, you can make perfect reflections only for planes and spheres "
This is not true.
I think, Blender’s reflection is 99% unusable.
You can make individual spheres, planes… but for what? Object can’t intersect others, because the reflection will bad…
endi, you’re a great artist and you probably always strife for
perfection but blender’s EnvMap are not that bad 
You can mace recurrent EnvMaps now, and I’m used
at solving the intersection problem by using booleans/knife.
Stefano
hm, yes, with booleans and knife oh… this is a very stupid method I think for this
hehheh… oh man.

S68: Sorry to disagree, but you cannot do perfect reflections on Spheres. The reflections will always be too big.
intrr: Mmmm…
are you sure? In BgDM’s tutorial and in any example I tried to make reflections look very OK.
I’ll try this.
Same environment, Blender and Yafray, the latter being reference…

S68:
The “mirror point” has to be different for each point on the surface on the sphere. If you place 1000 empties in your scene, and assign each face of the sphere a different material and envmap, it’s probably achievable, but maybe it’s more practical to use a raytracer 
intrr: no, because a perfect sphere as one and only one focal point.

SO intrr,
Which is Blender and which is yafray?
Stefano
The first is yafray.
