neon tube 3d model

Change the texture of this pic as described below. Base Material: A smooth, semi-gloss plastic/rubber tube. Surface Finish: Overall glossy, with medium–high specularity. Highlights are soft but pronounced, similar to polished polyurethane or PVC tubing. No micro-surface roughness; the finish should appear slick and evenly reflective. Color Characteristics: Solid, uniform bright yellow with no visible texture variation. Subtle tonal gradient along the sides to simulate curvature, but the base color remains consistent. Geometry & Form: Tube should be modeled as a rounded, slightly inflated cylindrical extrusion, not a flat ribbon. Cross-section: circular, medium thickness. Edges must be smooth with gentle chamfers or bevels. Subsurface / Light Behavior: Slight subsurface scattering (very mild), enough to soften the highlights and make the material look soft and rubber-like, not metallic. Shadows should be soft, suggesting a flexible material.
