I finally found time to render an old scene I had given up on due to the long
render times. Even with 3.7 and 4 cores it took a couple of days to render. I
think I went a bit o.t.t. on the focal blur though.

Holy Moly! The render time definitely was worth it.

As for the focal blur, I think it's perfect for the size.

Now that's photo-realistic!!!! ... focal blur looks fine to me as well.

Yes, no wonder I gave up before, I reworked the rock texture on this one 
as well which I think made it slower (several layers and a couple of 
nested texture_maps). Also bumped up the focal blur quality settings a 
bit, this is the main thing that slows it down, the image with low 
quality focal blur or just AA only takes a couple of hours to trace.

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.

Sean
