Got it to work. Make sure you have the latest ruby
Now I need to find practical ways to apply it.
Where would one get or create the data files where they could be applicable?

Ok, got the dat file to download now. Now it does nothing

Thanks Gaieus,
But I get thid error message after loading the example "ioc_dat.gif" file.
Any idea what the problem might be?

This stuff makes you feel really humble. This is fantastic!

Gaieus,
Can you post a test file or link to a data file? I would like to test the cloud ruby.

Great images Fred don't stop posting please!

Thanks for the assist Gaieus. I could never get that Heightfield to work with anything of significant size. This was some time ago, I gave up Maybe it's improved by now. It's in the right hands now. Here are some old links for more background:

Have you done any experimenting with Heightfield ruby? Where displacement is done by a grey scale image. The darker areas are the lowest point and the highest point are light.

Rick, could you point me to an illustration. I'm sorry I'm still not understanding your explanation We may be talking about different things. I guess I mean frame depth.
I have to push-pull frame depth manually, right?

You can't have a good render without a good model but you can have a good model without a render.

I wish I had your skills wow!

I did say bugs bunny I mean't Tony the tiger, GRRRRRRRate!!!

Nice Fredrick, How do you know which IES light to use? Most are very similar in look to me.
Is there some rational way to pick from the very many vs trial and error? I recall seeing a distibution chart and again there are so many that seem to be really close in value of how they look.

Nick, excellent!!!

BUGS BUNNY, THATS ALL FOLKS

Pav,

I think we have another way of achieving this. I would draw my plan lines and drape them over the terrain. The terrain has to be mesh though. The lines will cut faces in the terrain and then paint faces .

Can parametric tool be added this. After or during adding shape you can change radius or height parameters. VCB stuff you know. Now this would be fantastic!!!

Can someone reup the file?

Has anyone tried exporting to see how it looks i.e. parking lot lines?

scooby doo!!!

Thanks guy's. Gaius that grass is beautiful, I'll use that on close ups. If you look closely at the photo it's more like small clusters of bushes as grass. I'm trying to mimic the texture and controlled shape. Maybe I'm too picky Here's the scene I will be using.

ps at this dist Kris's grass may work fine, I'll try it.
