It does not have any Diffuse/Transparency/Sub-surface Scattering effects. When Metalness is 1.0, the Physical Material is considered opaque.Even if the Reflection weight is 1.0, the actual reflectivity is lower due to the Fresnel curve energy is taken from Transparency/Diffuse/Sub-surface Scattering only relative to the amount defined by the curve.

When Metalness is 0.0, Reflection weight takes the angular dependency (Fresnel effect based on the Index of Refraction or the custom curve) into account.

Reflections take the weight of all other layers.

If the Transparency weight is 1.0, there is no Diffuse or Sub-surface Scattering.

Transparency takes the weight from Diffuse and Sub-surface Scattering.

If the Sub-surface Scattering weight is 1.0, there is no Diffuse.

Sub-surface Scattering takes energy from Diffuse.

To be notified as soon as Mental Ray is available for you to use within Max 2018.Think of the energy conservation logic as layering of shading effects. NVIDIA's FAQ about Mental Ray for 3ds Max is located here. As such, we know how important that is to many Max artist's workflows, and we don't want to curtail that. Unlike Maya, which just added the ability to render a sequence with the GUI up in Maya 2017 (?!), Max has been able to do this for over 20 years now. With Max 2018 now in hand, we're now able to do final release testing, which usually takes a couple of weeks.Īs mentioned, our product model will be similar to what we did with Mental Ray for Maya (where you only need a license for some form of network rendering) except that there will not be any restriction on single frame rendering within an active Max session. Yes, Mental Ray is on its way to Max 2018, and should arrive for everyone in the next few weeks.
