Our intention is to make curved geometry for grass blades instead of flat planes so they can reflect light naturally. This is more or less an average height of human eye thus it will give us the proper point of view. From Camera->Standard->Target we create a standard 3ds max camera targeting the ground with approximately 170 centimeters distance from the ground. We place also a CoronaSun and a tree somewhere and play around until we find interesting shadows on the ground. It is obvious that this technique is followed not only in plane surfaces but in any kind of object (standard primitives, extended primitives, compound objects etc).

This step will give some realistic bumps, make our ground less flat and capture more interesting shadows. We make a plane surface 1000cm x 1000cm with 100 length and width segments, apply an Edit Poly modifier and we make some push and pull paint deformations. Ground Preparation for our Architecture Renderingįirstly we need to make the terrain where the grass will be scattered.

We can also see some small flowers on the grass.

Patches of dried or dead grass where soil is visible.

Different kind of plants randomly placed and.

In the photo bellow some useful notes can be extracted:

How Does Grass and Lawn Look in Reality?Īs always our target is to imitate real life so we must pay attention to the subtle details of a real reference photo. We click the button Save as Defaults and finally we setup Gamma/LUT Correction and System Unit. The technique in this tutorial could be used also to generate similar scenes of any scattered content that needs to be spread over a certain area.Īs we described in past tutorials first thing to do is to set Corona as default renderer, from Rendering tab->Render Setup->Common->Assign Renderer and set Corona Renderer as Production.

Make clusters of grass and scatter them across the ground surface.

There are five discrete steps a 3d artist must have in mind: In addition we share our grass blade textures with you, so grab this free download! But now let´s get started! Usually most private residences are surrounded by yards with short cut lawn so we should be able to render this kind of “foreground” on our own for your next architectural visualization job. With this technique you can create super realistic grass and lawn for your next exterior architectural rendering project. Therefore we will first model and texture the 3d grass blades and afterwards use a “Scatter Plugin” to randomly distribute the single blades of a large surface. In this tutorial we will show the procedure of making a grassy field in order to enhance realism in our exterior architectural visualizations.
