The next challenge I was set at Lightmap was to create balloon style text in Cinema 4D, Modo, Maya and 3ds Max; rendering in Octane, V-Ray and Modo. The purpose of this project was to expand my knowledge and skill-set using a variety of software to model, sculpt and develop the perfect balloon text. My plan involved creating plastic and nylon metallic style balloons using ‘HDR’ as my design, which may seem straightforward enough, but for a relative novice in balloon creation, it presented numerous challenges.
Learn how the size of objects is represented in a HDRI environment.
Let’s take some time to understand how the size of objects is represented in a HDRI environment. The most common type of HDR image format used for lighting in CG rendering is the Equirectangular format. This rectangular image format has a ratio of 2:1 and when mapped onto a sphere it correctly represents the viewpoint looking around a full 360 degrees in all directions from a point in space. These images can be created in a number of ways, but for the purposes of this discussion, lets imagine they are being captured with a Spheron camera system.
