i think it looks great, only thing it needs is a cleaner render. (oh, yeah, attachment size, very small)

hey how about this, grit3

You model all that? I have to say it look incredible. Great job!

wow. those are great! They looked like the real thing. I think it's because of the bronze (and the areas where they seemed to fade off). Great work :)

By the way, which dirt shader did you use?

:applause: That is AMAZING Xiao_x! :applause: Really GREAT job! :thumbsup:


Btw, if you are using LW8, take a look at this Docuwild's shader:

I think is quicker than Grit, more stable and very versatile too :)

That is lovely modelling/texturing work there. Good use of grit too.

Amazing work! :applause:

Whenever I tried some of the free dirt shaders I didn't get really good results. After looking at your image I've come to the conclusion that I wasn't patient enough!

The dirt on the statues looks very convincing IMO, couldn't have handpainted that better.

That looks really awesome man! Very impressive. My only crit would be the blue plane, it looks really simple, for such a realistic scene I would add some texture to it and try to break up it's line in the background.

sorry for this,i really a lazy guy........ :blush:

gerardo,what the plugin u recommend is cool,that is fast for building and plane object...but i`m try that for my sculpture model,i found that is a bit longer than grit2 :shrug: But in my opinion,this really cool plugin because more stable.
one question,=====>why after add the plugin will see `rendering transparent` at rendering
status???i didin`t have any transparent surface and ray trace transparent..... :shrug: ???

The other option is TB_dirt http://home.att.ne.jp/omega/tabo/3dlabo/p_lwp.html. It's stable, and I've found it to be the fastest of all the options for dirt (excluding SG_ambocc which isn't really a dirt plugin).

Yes, I was revising this plug the other day and it's very promising. I have 2 suggestions for this shader that I think are not so difficult to implement and they could transform it into the best occlusion shader (no dirt shader):
The idea is that any of these parameters has an envelope:

http://www.geocities.com/gerardstrada/TBdirt.txt

Additionally would be necessary a sampling angle that rotates in the axis of the normals. The idea is to make an envelope and to use MotionBlur; this way we would not need to use more than 6 samples in single_sample_ count, what is really very fast. :bounce:
I hope somebody who speaks Japanese can make this requested to the author :applause:
Btw, this is applicable also for SG_AmbOcc that only needs to add an envelope to MaxRayLength. This would allow us to use much less number of rays.

Xiao_x: That topology is impressive! :thumbsup:

SG_ambocc


[Ambiant Occlusion shader - not really a dirt plugin, but this little beast hasnt left my side since we met.]

[edit:]

- amazing pic btw. have some statues like those. had to go get them to compare. spot on.

TB_dirt stuff

What about having a min and max and an offset setting for sample angle, aswell as a world co-ords checkbox. This way you could have all your samples pointing down or in a certain direction which would be VERY useful for rust and fluid (that obviously only drips downwards), and the offset could be used to spin the samples around for your spinning motion blur trick :P Grit3 has the vertical toggle thing so the dirt only points down which is an excellent feature, but TB_dirt is alot more stable :O

As for SG_ambocc, I had a bit of fun yesterday with this image. It could use work but I'm not particularly interested in going back to it. Used point lights for sky ambient (1 in center of top dome, another near the bottom where it would bounce off the floor). Again, it's not dirt, but it sure is the bestess trick in the business for achieving a nice image :P

No; seriously, you have a impressive image there, Duke :thumbsup:
how much time took the render?

I think it took around 6mins to render at that res, 5 pass PLD/mitchell, 24 samples for ambocc.

You know, unless I've missed something completely obvious all the options in that photochopped picture of TB_dirt's options panel exist in ee_grit3... :) (except sample jittering)

They do, but in TB_Dirt my scene doesn't turn purple :O

Or stuff like this..

Don't get me wrong, I was a huge fan of Grit2, but Grit3 is too unstable for the time being. I'll wait for another release :)
