Thanks, I often use focal blur to hide things I don't like in an image 
;-) but in this case it was just as it was meant to look like a macro shot.

The moss and rocks are gorgeous. I too think the focal blur is just right.

One of the best photo-realistic images I have ever seen. Well worth the 
render time.

Moss: blobs?

Hi Thomas,

The moss itself is a mesh object but there are also blobs underneath the 
moss. I place blobs using trace onto the surface of the rock then use 
trace again to place the moss plant onto the blobs. The blobs can be 
used to add a less even look if the surface is flat (not really an issue 
in this case).

It is pretty much the same moss macro that is used in my old train scene 
just with a different mesh object for the moss and an added parameter to 
determine how many of the seed pods are place.

I will probably combine the two macros together so you can choose from 1 
of 3 types of moss with or without seed pods. Happy to uploade it if 
anyone wants to use it, there is nothing particularly clever in there 
just trace and some parameters to adjust scale/size/randomness etc.

Moss has always been one of my long standing todo things, so I would be 
very interested to see the macro once it is complete.

   I second that... the colors are so natural! Very well done, Sean.

I would really appreciate to learn from your code, this one is really excellent.
May be you consider your moss object itself as "not particularly clever". You
are wrong with that. But as with your train, your guitar, or the stones from
your (natural history) museum your textures are really wonderful. I would really
like to learn how you did the stones or the moss here.

I personally think that your use of focal blur here is completely correct and
not over the top. In some areas of the picture it looks like a little bit to
much, but this seems to be more due to the geometry of the scene which looks a
little bit like the edge of the step of a staircase. In this case you must have
smaller areas of sharpness and decreasing sharpness down the stairs which seems
to be the case here. So I interpret the settings as correct.

Best regards,
Michael

Hmm that's an idea = put some moss on your stones =)

Going slightly ot, Iwould like to see those stones in a babbling brook or  
a river :)

Hi Michael/Thomas,

I have not added the other moss types yet but for now have uploaded the 
source to this scene to the p.b.s.f group. It contains the macro and 
moss meshes for this scene but not the other two types of moss, at least 
one of them was used in my train scene though so should be on the irtc 
site.

When (or if knowing me) I modify the macro I will upload any updated 
versions..

The moss will not hold up too well to a real close up, something I would 
like to improve as well..

Sean
