This was just a quick test of the blurred reflection texture which Nemesis
posted a little bit ago.
I was interested in a) how subtle I could make it, and b) how it looked with
HDR lighting.
Thanks to Nemesis for the idea and to Jaime Vives Piqueres from whom I stole
the sphere texture.

hmm? i take it the blurred reflection is on the blue box? The effect is
barely visible, perhaps because the box is so short. I wonder how would
the ball look with it... :) hey, you know with some code tweaking you can
apply JVP's texture to the averaged blurred texture as well, so it's a
composed texture. Should look nice. It's nice right now.
but, is that megapov?! doesn't it come with blurred reflections anyway?

Yeah, it is barely visible. I just wanted to see how it would look as a very
subtle effect - not as the main course. I also wanted to see how it would
react to HDR lighting, which is why the main surface is on the top. I see
something that may be artifacting on the top right corner of the box, but
that might just be a reflection from a dark portion of the hdr map.

Yes, MPov comes with blurred reflections, but I wanted to see how your
texture looks.
I think that it looks quite nice. I did some other tests where the blurring
was far more evident and it holds up well.

I don't believe those artifacts will go away even with very strong
supersampling method 2 antialiasing... you can always try in a super big
resolution and heavy AA, though :P

hmm, glad to know. :)

Nice try, Billy Boy!
The only thing I would suggest to change, is the reflection itself. At the
current version, it looks like the underground is one big part only printed
in different colors - the reflection continues from tile to tile.
But if these are supposed to be real tiles, the bumpy reflection should have
its own pattern for each tile. Means, you do not create a checker ground and
add that nice bumpy surface, but you create many flat boxes besides each
other each with its bumpy reflection. Important is, that the individual
bumpy reflections stop at the borders of each tile, and continue in a
different manner with the next tile.
Hmm, my English is not so good, sorry. Did you get what i wanted to express?
I like your scene, go on with it!
Greetings,
Sven

If a surface normal is sufficient for his purposes, then a matrix of boxes
is unnecessary. Discontinuous bump patterns can be effected with a 4-part
tiled texture, which can be built up with checker and gradient. As long as
no adjacent tiles carry the same sub-texture, the continuity won't be
evident.
