The egzVRay materials are finally (yes, I know it’s been forever) being updated to support V-Ray 1.5 SP3. Those interested may apply for beta testing.
The new materials will add support for V-Ray 1.5 SP3, and includes an updated egzVRay glass material, a rewritten carpaint material, a dispersion glass material. Other materials may be added as well. The old egzVRayWax material is dropped because of the addition of VRayFastSSS2 to V-Ray.
