Absorption is a volumetric effect, so thin parts of the object will appear more transparent, and thicker parts will be more colored. It is recommended to always leave caustics disabled, unless they are absolutely necessary.Ībsorption can be used to control the color of the glass material. Higher values will make the glass appear "heavier" and more reflective the value of 1,33 can be used for water material.Ĭaustics can be enabled for solid glass materials, however this will always make rendering much slower, and will introduce a lot of unwanted noise. IOR under reflection and refraction should be left at the default 1,52, or slightly adjusted if needed. Reflection and refraction levels should be set to 1. In this extreme example, Fresnel IOR was lowered to 3,0.įor glass materials, same as with metal materials, diffuse level should always be set to 0, or diffuse color set to pure black. Diffuse or reflection level should not be changed. Metals with lowered Fresnel IOR value will appear darker. In this case a simple noise map was plugged into the diffuse slot. Again, the diffuse color or amount should not be touched.Īdditionally, the realism of rough metal can be increased by adding structure to its surface. In this case, reflection glossiness was lowered to 0,7. Rougher metals will always appear brighter. Diffuse color should not be used, as in case of metals it should always be set to pure black (or diffuse level 0). The color of metals should be controlled by their reflection color.

This guarantees that the materials will be always set up correctly.
