Texture Paint: Various Shaders aren't Respecting OCIO Colour Space
Closed, ArchivedPublic


System Information
Linux AMD64, Debian Squeeze

Blender Version

Short description of error

When using a 32 bit generated texture with Texture Paint mode in the 3D view, the colour picker nor the viewer properly respects the colour space selected. Painting in an emission, diffuse, etc. shader is totally broken. The UV Image Viewer however, completely respects the OCIO configuration and reference space, properly displaying both the picker and the proper internal reference values when painting.

Exact steps for others to reproduce the error

  1. Paint using Texture Paint mode using any OCIO configuration other than the default.
  2. Reference space values will be incorrect.

Replace colormanagement directory in `blender/bin/[version]/datafiles/colormanagement` with the configuration at

This is a known limitation of viewport: OpenGL still stays sRGB space.

So thanks for the report. but it's not considered a bug atm.
