In this tutorial we delve deep into the Global Illumination and Environment system featured in Turtle 4.1
It takes some time with any rendering software to get to the point where you’re confident in setting up a beautiful render. This tutorial will attempt to provide you with lots of shortcuts that can help you get really nice renders in Turtle and lay out a good workflow for lighting many different types of scenes. You’ll also find in-depth technical notes on a lot of the components and concepts included in Turtle’s Global

The Lightwave 3D renderer is one of the most widely used in Film and Broadcast production because of its quality, workflow, and speed. It can now do image-based lighting due to a number of architecture enhancements in the 6.0 and 6.5 versions. One of these critical new architectures is a full precision rendering pipeline from top to bottom. Another critical ingredient is a global illumination model. Global illumination simulations produce more accurate images of lighting in scenes, by considering more light sources than simple illumination models.
