We need to tell Octane which environment we want to be used for lighting and reflections (Primary environment, default), and which we want as a background image (Visible environment). To do this, we need a second Octane Sky by duplicating or getting a new one from the Objects Menu. The total number of frames for the scene is 90.We can completely replace background with another image, solid color, or gradient. Then, continue the comparison with a final scene merged by these materials. With the same lighting settings, we’re gonna compare 6 types of materials, including diffuse, plastic, gold, glass, jade, and texture. In this post, we’re gonna do a speed comparison and render on a 4x RTX 3090 server on the iRender cloud. But you get real results without changing the settings because it’s done inside the engine itself. With unbiased render engines, you have less control over the scene and light calculation. What an unbiased render engine means you can brute-force all the light calculations.
Octane is an unbiased render engine with real-time capability developed by Otoy. You can get faster light calculations and faster render time. Redshift offers more control over the scene and how certain aspects react to certain lights in the scene.
What a biased render engine means basically you can bias your light rays and samples to specific parts of the scene that may need more focus. Redshift is a biased, production-quality GPU accelerator render engine. But each one of them has specific different features. Indeed, they are both useful and powerful. Before jumping into detailed analysis, we want to talk about the overview of these 2 render engines. They’re so-called Redshift vs Octane that have widely affected the CG industry. We decided to make a series of comparisons between a biased render engine and an unbiased render engine for Cinema 4D. Receiving dozens of questions from our customers asking about Redshift vs Octane, which render engine is best for Cinema 4D software with GPU rendering?
