I want to render a plane with a linear gradient texture that can be rotated as needed.
I can rotate the gradient using the Mapping Node - > Texture -> Rotation.Z coordinate, however the rendered gradient is always logarithmic rather than linear:
This is the true linear gradient that I am looking for:
I've played around with the scale and location vectors but they have no impact on the linearity of the gradient.
Here's my scene (1 plane, 1 sun lamp, orthographic camera):
A similar question was asked a while ago over here but no real answer was given.
Any suggestions would be appreciated.
It seems this may be due to the Color Management applied by Cycles. I'm using Cycles because as I believe you can't rotate gradients (blends) in BI. If this is not right, please let me know.
I'm really just trying to determine if it is possible in Blender to render 2D shadow mask planes using true linear gradients. I alrteady have 3D geometry that the masks need to fit perfectly against, so I extruded edges from these objects to create new 2D planes.
