One interesting trick is that if we use this Mix sky texture method, we can turn the sunвЂ™s power to zero, and then use other Octane Lights to light the scene and control the shadows while still keeping the reflections and background from the HDRI. Above all, the important ones here are the Power which makes it brighter or darker, and the Sun size, which makes the shadows sharper or more diffuse. If we want to be physically accurate about it, weвЂ™ll need to match the position of the sunвЂ™s light source with the one in the HDRI.

Rotating the light on the P axis (red handle) makes the sun rise and set (and colors it accordingly) while rotating it on the H axis changes the position of the sun in the sky. ДЄfter that, we can change the position of the light by simply rotating the Infinite Light around. In the DayLightвЂ™s tag options, we need to enable Mix sky texture. We can ignore the Sun tag and the Infinite Light settings because what we want to focus on is the Octane DayLight tag. This makes a C4D Infinite Light with a C4D Sun tag, and also an Octane DayLight tag on it. Next, we can drop in Octane DayLight by going to the Live Viewer, and under Objects>Lights, choose Octane DayLight. Having a plane with a shadow catcher material on it is useful as well to see the shadows. If we were to look at it in the Node Editor, it would now have an RGB Spectrum node piped into Environment tag instead of ImageTexture node.ДЇirst, we need an Octane Sky with the Octane Environment tag on it and an HDRI loaded into the ImageTexture tag. The completed Cinema 4D scene is now ready for rendering. Paint your shot with lights in HDR Light Studio (Lights are automatically created in Cinema 4D as you light) Finish - HDR Light Studio generates high-res HDRI images for your lights. Same as choosing вЂњTexture Environment вЂќ from Objects menu in the Live Viewer. Press Play and the Cinema 4D interactive render shows in HDR Light Studio. That replaces the ImageTexture node with RGB Spectrum node. For a solid color, click the green circle icon under the word вЂњMainвЂќ in the Environment Tag for Visible environment.

JPEGs are smaller and less resource-intensive. HDR image because we donвЂ™t need all the extra exposure data. In this case, JPEG or PNG would do better than a. For the second sky, in Environment Tag options, pick Visible environment from the Type dropdown.ДЄnd if we were after a different image for our visible background, we go into ImageTexture node and swap the HDRI with something else. 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. We can completely replace background with another image, solid color, or gradient. Select where you want to save your FBX then click Save. To export an FBX, first select the File -> ExportвЂ¦ -> FBX (*. How do I export FBX files from Cinema 4D?

to add 3D depth of field, optical accurate motion blur, area shadows, ambient occlusion and more to your scene. The Physical Render Engine in Cinema 4D lets you render with ultimate realism using real camera settings like focal length, shutter speed, aperture, etc. The first thing you can do with projects to speed them up is reduce the number of times a reflection can bounce from one shiny surface to another.Д¤. This renderer has been built around rock-solid features and uncompromised quality. ItвЂ™s also been used in film production for over fifteen years.
