HDR color with V-Ray Color Picker

Can I set the value of Float 1.0 more higher (Very bright color) with the V-Ray Color Picker?

How to set Float 1.0 more higher color arbitrarily with V-RaySketchUp / Rhino ? (without multiplier)

Hello, and apologies for the late reply!
The color picker range is set between 0.0 and 1.0. There is currently no workaround without using a multiplier.
Using a Simple Mix texture or a Temperature texture allows multiplying the color value.
What is your purpose for using exceedingly bright colors?

Kind regards,
Peter

Sorry. I forgot the existence of Temperature texture.

V-Ray Rhino/SketchUp’s V-Ray Color Tex has only a color box.

Temperature texture is equivalent to 3ds Max’s V-RayColorTex.
