Diffuse Level (Oren-Nayar only)
You can use this parameter to alter the strength of diffuse reection for Oren–Nayar. The default of
100% means normal diffuse reection — enter a lower value to reduce the amount of reection.
Roughness (Oren-Nayar only)
Adjust this value to match the roughness of your material. The default setting is 50%.
Texture Preview Size
Here you’ll nd entries from 64x64 (16 KB) to 2,048x2,048 (16 MB). The value controls the internal
resolution of the texture — the higher you set this value, the more detailed the texture will be in the
viewport. The value has no effect on the rendered result.
Proceed with caution when increasing the Texture Preview Size. Higher
settings require more RAM and increase the lesize of the CINEMA 4D scene.
OpenGL is also affected because the texture previews must be loaded into the
graphics card’s memory.
The ‘Default’ value corresponds to 256x256 (256 KB).
