Make gravel dirt road look more realistics

[shaisamuel]

Hi,

I am new to rendering, watched some of the tutorials, and am trying to get my complex model to look more realistic.

In my model, I have gravel roads, done with texture. As you can see in SU it looks like, but on the rendering, it looks like a shiny surface.

I couldn't find any material to match gravel in the library, and I also wonder how can I create some dirt (noise) on the surface, as it probably looks in reality.

Another issue I have is with the net fence in the far background. I is made with net texture, that has holes in it on SU. When the net is close enough it looks OK in the rendering, but when it is far, it looks like noise. Anything to improve it?

Thank you in advance,

Shai

Just a caple of more images to demonstrate the gravel and fence issues. The gravel road looks too clean and plastic, and not like a dirt road. Rendering is at 07. High+, Camera Only, 1920x1080, and the standard Sketchup View lens setup.

By the way, the skies, are a test I have done, with an images which is not seemsless, and therefor, doesn't fit.

Hi, welcome to Twilight Render and to the world of rendering.

You will need a much, much higher quality texture map for the wire fence (do an image search for .png images only and look for "chain link fence 3d texture") and for the dirt/gravel road surface. It is now "tiling" strongly because it is very low resolution. Most default SketchUp materials will do this, as they are intended to be very quick to visualize in SU viewport on your GPU, but they were not intended to be rendered.

The "noise" of the fence is from the moire pattern that happens in 3D rendering or in real life - render image on Easy 09 and it should go away. Or render with much higher image resolution.

A professional workflow would be take a plan view snapshot of your entire plan, open this into Photoshop and import a very high quality road texture and do a "matte painting" of the texture onto your road surface, then you would also paint the dirt tracks, etc. Then you would import that high resolution texture into the SketchUp model and paint it by projecting it straight down from plan view.

For Twilight Pro users - find the high resolution groundcover gravel texture at the very top of this post: Subject: Textures for Twilight - High Resolution

Another option, one typically taken by an architect in a hurry, would just be be using a better quality texture. There are many texture websites out there. See some links here, search this forum, or on the web.

Another option is to use a texture generator such as materialize or shadermap or many many others - do a search.
