Billabong Posted February 13, 2008 Share Posted February 13, 2008 I am having a problem getting my grass not to look so tiled. Right now i am using the vray displacement method modifier, I tried using the vray fur, but since this is such a large area, its taking 47,000 hrs to render and this may have to be animated, the painted red line you see is where the treeline will be, but you see you will still be able to see the tiling, is there a better texture out there that i can use or another method. I have been racking my brain on this for a about 2 days now. I really appreciate any help and my vray dismethod settings are 2D landscaping I am using the grass diffuse from the material as the texmap amount is .2 resolution is 2048 precision is 16 thanks again Link to comment Share on other sites More sharing options...
Logitek Posted February 13, 2008 Share Posted February 13, 2008 Hello Brandon, The first question that comes in mind is "Do you really need displacement on this grass from this point of view?" If your camera stays that far away and up, I would definitely not use displacement. For huge grass areas (or even the smaller ones actually), I use noise materials (noise material inside another noise material...) and I never have to worry about tiling anymore. Once you've found a grass that works, save it and use it everytime you need grass again. If you have a camera that's a lot closer to your building and you want displacement, it's a good idea to divide your grass into 2 separate objects. One for the front on which you put displacement, and one for the back that doesn't need displacement. That will save you a lot of time in rendering. I hope this helps.

Billabong Posted February 13, 2008 Author Share Posted February 13, 2008 Thanks so much for replying. Would you mind elaborting or even sharing anoise setup, that you were refering to.Just so I have complete understanding of it thanks again Link to comment Share on other sites More sharing options...
Guest nazcaLine Posted February 13, 2008 Share Posted February 13, 2008 create a blend material, with two colors of grass. use a mask like noise, smoke or dent, and play with the settings til you're satisfied. (i prefer smoke) cheers. Eduardo Link to comment Share on other sites More sharing options...
Logitek Posted February 13, 2008 Share Posted February 13, 2008 you can also add one or several noise modifiers in each one of your blend materials. That will create even more color variations to your grass. I also like to change the tiling of the smallest noise (like X2.0 and Y0.2 for example)... that stretches the noise to make it look even more like grass... But like Edouardo said, make some tests and you will quickly understand the concept and have good result I'm sure. Good luck, Matt Link to comment Share on other sites More sharing options...

Logitek Posted February 13, 2008 Share Posted February 13, 2008 Looks very nice Brandon... Mind sharing your settings? ahaha (just kidding) Link to comment Share on other sites More sharing options...
Billabong Posted February 13, 2008 Author Share Posted February 13, 2008 haha, sure its actually 3 different grass bitmaps in a blend, worked out very well Link to comment Share on other sites More sharing options...
Billabong Posted February 13, 2008 Author Share Posted February 13, 2008 Just out of curiosity, this same method could be used for asphalt as well, correct? Link to comment Share on other sites More sharing options...
Logitek Posted February 13, 2008 Share Posted February 13, 2008 yes, you can even use this with bricks if you want! Link to comment Share on other sites More sharing options...

Guest nazcaLine Posted February 13, 2008 Share Posted February 13, 2008 ...and you can use a blend material inside a blend material and make it even more powerful and complex. i got really interesting results with this. Link to comment Share on other sites More sharing options...

Eric Sosa Posted February 26, 2008 Share Posted February 26, 2008 just find something for you guys to use on those large grass areas; no tilling...but noise instead!, no blend , no fyr, ...very simple http://www.cgarchitect.com/vb/28724-large-aerial-view-grass.html [ATTACH]24869[/ATTACH] to be rendered with standard max Link to comment Share on other sites More sharing options...
Itam Posted February 26, 2008 Share Posted February 26, 2008 what don't you understand? How do I used the blend material for that? and how do I apply more blends? Were do I put them? in Difusse and in bump? Link to comment Share on other sites More sharing options...
ramy Posted June 3, 2008 Share Posted June 3, 2008 Here is a solution I came up with for grass that works far away as well as up close. Hope you like it. Link to comment Share on other sites More sharing options...
Claudio Branch Posted June 3, 2008 Share Posted June 3, 2008 Here is a solution I came up with for grass that works far away as well as up close. Hope you like it. Nice solution! I downloaded the Max file from your site, but I got an error message (mentalray_plugins.dlo Class: Photographic Exposure Control) when I tried to open it.... Anyways, my question is how do you get the shader to change based on the camera's distance to the object (with the assigned shader)? Link to comment Share on other sites More sharing options...
blowback Posted June 3, 2008 Share Posted June 3, 2008 nice, this looks pretty cool. can't wait to try....thnxs Link to comment Share on other sites More sharing options...

Anyways, my question is how do you get the shader to change based on the camera's distance to the object (with the assigned shader)? The max file is for max 2008 or newer and has mr Photographic exposure set. Be sure you're using mental ray as your rendering engine. The changing shader by distance is all done with the falloff map.
