I have a issue today (among many others ;)) that if I render a view the gravel becomes to look like a carpet.
Anybody that has any ideas on this? The material should be looking good independent of the view distance, so it should look good on close-ups and from far away. For fine materials as concrete it's not an issue, but when it comes to more coarse materials like this gravel it harder.
Daniel,First thing that comes to mind is that the texture being used is a rather small one. I would suggest using a larger texture. Not necessarily a higher resolution, but a picture of a larger area. Many can be found on the web. Adding another layer on a larger scale to your texture may add a feel of irregularity. Some dirt or a soft shade of something. Use a bump map and give it a low value. This will suggest some height and take away the flatness.Many free textures can be found here:http://www.cgtextures.com/ http://www.freefoto.com/browse/33-00-0/Textureshttp://backgroundsarchive.com/http://www.animax.itIf you quickly need to test if the images you downloaded are tileable (seamless when placed side by side), download a tool called TextureDiscovery. It's a free gem and it can be found here:http://www.texturemaker.com/download.php . Another option would be to buy a proffesional texture CD, like from http://www.marlinstudios.com or http://www.arroway-textures.com/. Of course you should try the free options first.

...Or simply create a procedural material, and never worry about repeting patterns.
I'm with Kurt on this one. Try mixing a couple different procedurals to see what you can come up with. The ground on this is my take on some quick procedural gravel.
yes - mixing different procedurals is the way to go to make it look natural and still render very fast.
Hi, sorry for my delayed answers. But I can't get the results as you get using procedurals? Are you using SS3? From what I understand this is improved in SS3. If that's the case I'll just have to wait for SS3 to come out from it's beta stage.
MicroStation 08.11.09.829MicroStation Connect Update 11ProjectWise 08.11.11.590LumenRT Update 11
Did some testing now in SS3 and the result is promising. Think I actually now has a result that is good enough.
What need to be considered is that the area that is filled with gravel many times is between 2500m2 to 375000m2.
Attach a sample of a test file.
Thanks all for your help!
And a close up
there are improvements to procedurals in SS3, this is why I removed my material example (made with SS3) previously posted in this thread. Since you now are using SS3 I will re-post my example here:
no displacement, only bump - and it renders very fast. Can be improved to look more natural by mixing more procedural channels, but this is just a quick and easy test....
