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 Total Light, Raw Total Light, Normal Map and Bump Normal Map. 

Splines with a Renderable Spline tag are rendered as thin-walled objects.

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, and these . These parameters must be used to specify the start/end width of the spline.
