Everybody uses IES lights in arch viz renderings but most people use ready made files provided by lighting fixtures manufacturers.
However, if you are in a creative mood, or just can’t help yourself from controlling every little detail of a rendering, you should definitely check out the latest tutorial from Jamie Cardoso.
In this tutorial he talks about how to create your own customized IES files with the help of a small piece of software:
There are certain elements that can either improve or bring down the overall quality of an architectural visualization image. 3D Vegetation is an important factor and has a great impact on the final look of a rendering. In some cases, using cutouts of trees, bushes, etc. can be a quick solution but most of the times using 3d geometry is the way to go.
However, creating 3d vegetation that looks convincing can prove to be quite a challenge. I have compiled a list of 11 tutorials that help in this regard. Some of them require plugins while others use the default instruments available with 3ds max and V-Ray.
In the following tutorial we will create an advanced rusty metal shader. Although the tutorial makes use of vray renderer’s vray blend material, you can also use shellac material if you are not a vray user.
In the following tutorial we will go through the process of rendering an image in separate passes using render elements and compose them afterwards in photoshop.
Although I am a vray user, the same method can be used for any other renderer that supports render elements.
