Section

Column width 50%60% The Spline Color Correction texture is one of the three available color correction textures along with Color Correction and Bezier Curve Correction. The Spline Curve texture allows remapping any other texture color values using RGB or HSV curve controls. UI Text Box type tip To color-correct a specific texture using a Spline curveColor Correction, simply right-click on the texture slot to bring up its context menu, select Wrap In and choose Bezier CurveColor Correction. This will place places the existing texture within a Spline Curve and then plug Color Correction and then plugs it in the original slot. UI Text Box type tip Any texture can be replaced via the Replace With New Texture (Image Added) button, which activates when you select the texture to be replaced. If the texture is an instance, all copies are changed as well. Column width 5%   Column width 45%35% Image Modified

Section

Column width 50%60% Input – Specifies a color or texture to be curve corrected. When a texture is selected, it overrides the color as long as the texture checkbox is enabled. Mode – Changes the set of curves used for color remapping. You can select between HSV or RGB mode. HSV – Hue, Saturation and Value curves are used for remapping. RGB – Red, Green and Blue curves are used for remapping the separate image channels. Interpolation – Controls the interpolation type of the selected curve control point. Note that the interpolation type only affects the curve section between the selected point and the next one. None – Disables the transition. Linear – Values are linearly interpolated in RGB color space. Smooth – Values are interpolated based on auto-generated horizontal tangents. Spline – Values are interpolated based on auto-generated and auto-rotated tangents. Position – Controls the position of the selected curve control point. Value – Controls the value of the selected curve control point. Values bigger than 1 can be used here if needed which does not affect the curve widget visually. It on the other hand has an effect in the rendered result and the texture Preview swatch. Column width 5%   Column width 45%35% Image RemovedImage Added
