This page provides information about the V-Ray Renderable Spline tag in Cinema 4D.
Overview
The Renderable Spline tag allows V-Ray to render splines. Splines can also be assigned with texture maps.
A temporary limitation is that only the U size is renderable.
Splines with a Renerable Spline tag are visible in the following render channels: Light, Raw Light, Total Light, Raw Total Light, Normal Map and Bump Normal Map.
Splines with a Renderable Spline tag are rendered as thin-walled objects.
UI Path: (Object Selected) Objects tab > Tags > V-Ray Tags > Renderable Spline
UI Paths: (Object Selected) Objects tab > right-click on object > V-Ray Tags > Renderable Spline
Starting with Cinema 4D 2023.1, the Renderable Spline tag resides in Extensions > V-Ray tags.
Common Properties
Render – Enables V-Ray to render of the spline.
Width Multiplier – Specifies the width of the spline in centimeters.
Width Mode – Specifies how the width of the spline is defined:
Linear – Introduces a linear (constant) value along the whole spline.
Spline – Introduces a width based on a curve, allowing different widths between different points of the spline.
You can create a new curve point using Ctrl + Left-click or by using a curve preset.
Start Width/ End Width – Splines in Cinema 4D do not have thickness. These parameters must be used to specify the start/end width of the spline.
Lock End Width – When enabled, Start Width controls the constant thickness along the spline.
