Friends I am sure somebody has good experience…
How to make a road on a land to look natural.
In my case, the road’s edges are not blend with the land as natural, so it looks artificial, though I use good shader for land and Road.
Is there any shader which will blend the roadways with land smoothly?
I am waiting experts advice

Dominic,
Can you show us an image of the issue?  Road and natural can have a lot of meanings.

thanks,
Yon

Sorry Yon,

I am not that good to explain what I wanted to have.
I have attached a photo and that will help what I wanted to have.
Plz check the edges of the Road & Sand in the photo.
How to bring the same effect in 3D. This is my question.
Bcz I am working on a large industrial area.. where many roads are used as models top of land (sand).

Hi Dominic,

Theres often no substitute for high-res texture maps (unless you’re so close you need extra geometry eg grass/rocks). You could try making a high-res texture as big as your road and land combined (take a screen snapshot from top view with both objects selected and resize in photoshop), and then apply to first the bigger object (I’m guessing land) then paste this texture from land to the road to maintain the correct size. This way you’ll be controlling the overall look in the texture rather than getting a hard edge where the road meets the land, which sounds like whats happening.

Alternately you could combine the 2 objects into one and reimport to achieve the same result. Also you could check out Turbosquid.com, there’s a lot of free or cheap tileable road (and grass/ground) textures there.

Dominic,
I agree with Rory, that the best way to make a realistic road is with the use of texture maps.  You could make a cliping map for the edge of the road to give it the uneven edge.  Basically having each texture (road and land/soil) on different layers would allow you to achieve a controlled over lap. Make sure they are not coplanar.

Image maps can be very large if you are trying to cover the entire ground area with accurate roads.  It may be better to to model the roads and have them stand up slightly from the ground plane.  If you model the roads with uv maps then the road texture can be small and tile-able, and the ground plane can be the same.

If you have the RAM, use an image map that cover the whole thing.  You can always use either a higher resolution ‘sticker’ for the close up area, or have a different layer for the closest area.  For tips on how to make the road on a curved path try this http://www.etereaestudios.com/training_img/vectorial_tips/pinceles_b.htm

You can run it through google translate to see it in another language.

Hi Dom

Rory and Yon are right. Check out the site www.cgtextures.com There are some fantastic road images and also some great sky domes.
