Avoid using 8K textures for small objects in the background. Reserve high-resolution maps for foreground assets.

Load your wood grain .jpg texture map into the Diffuse slot. Reflection Color: Set to a medium gray (RGB 128, 128, 128). Rhinoceros 5.0 x64 VRAY MATERIALS
Keep Reflection and Refraction subdivs between 8 and 16 for test renders, and bump them up to 24 or 32 only for final, high-quality production renders.
The V-Ray Generic Material serves as the primary base for most surfaces : Avoid using 8K textures for small objects in the background
Used for transparent materials like glass, water, and clear plastics. It requires an Index of Refraction (IOR) value to accurately bend light passing through the object.
Note: Rhino 5.0 primarily uses the .vismat format for older V-Ray versions (1.5/2.0) and .vrmat for V-Ray 3.0+. 3. Creating Essential Material Formulas Load your wood grain
Always enable Fresnel for realistic materials. This ensures the surface is more reflective at grazing angles than when viewed face-on. 3. Refraction (Transparency)
White means total reflection; black means no reflection.
Soft Gray RGB (128, 128, 128) with Fresnel checked. Fresnel IOR: 1.55 .
