showing grass in aerial view ?

[chow choppe]

hi

 

wats the best way to show grass on a vast area in an aerial view

if i use plain grass bitmap it looks too monotonous and repetitive.i also tried using a mix map with custom made mask but that also is not looking realistic.

displacement is not looking good in aerial view

 

any suggestions?

 

thanks

keep trying with blend mats, use 3 different ones, experiment with noise types for masks. try clipping the values(like (.45, .6) to remove the fluffly falloff areas.

 

or try making one bitmap for the view. maybe some mowing lines, this helps bring out the topography

You might also consider getting a hi-res aerial image of something like a golf course or a grassy field and Photoshopping out what you don't need...

agree with this, also using a mix map with some colour variations, i made 2 texture versions with some colour balance (between gerrn and brown) variations and using a mask to mix them...

also using a non regular displace map will help you...

if u are using vray use a vrayblend rather than mixmaps, faster, more stable and you can stack up more that 2 maps easily.

wud not want to phooshop it

 

i have given it a go with uvw unwrapping

will post some results soon

 

thanks

uvw unwrapping is basically photoshopping it!

The advantage to going with a hi-res aerial is that you can easily customize it with any additional features you like in Photoshop.

 

Here is a sample image from a recent project. The terrain geometry is mapped with a single hi-res image that I stole from another project and modified it for this one.

 

If you find yourself doing alot of large outdoor terrain projects, this approach becomes very effective because you save time using a texture that is already pretty close to what you need.

thanks claudio

 

but where do u find these high res textures

i spent almost a day finding these kind of images but to no luck

 

finally i had to make it on my own using grass pattern fill and using dodge , burn tools and changing hues in areas

 

thanks
