What it does

Scans every material's image textures (and world HDRIs) and assigns the correct color profile automatically, based on a suffix found in the texture's filename — e.g. _BaseColor → sRGB, _Roughness → Non-Color.

Installation

1. Open Blender® (4.2 or newer) → Edit > Preferences > Get Extensions (or the Extensions tab).
2. Click the dropdown next to "Install from Disk" and select color_space_converter_v1.0.0.zip — no need to unzip it first.
3. Enable the add-on if it isn't active automatically.
4. Open the 3D Viewport sidebar (N key) → Color Space tab.

Usage

• Convert All Textures — applies the colorspace to every image texture node in every material, based on the suffix list below.
• Convert HDRI — sets every World environment texture to Linear Rec.709.
• Matching is case-insensitive and checks whether the suffix appears anywhere in the image name.

Default suffixes

Editing the suffix list

Use Add / Remove below the list to create custom suffix → profile pairs. If you accidentally delete an entry (e.g. _BaseColor), click Reset to Default to restore the original suffix list.

Colorspace dropdown & favorites

The profile dropdown reads directly from Blender's active OCIO config, so every colorspace installed on your system is available — not just the five built-in defaults. Favorites are shown with a ★ at the top of the dropdown; nothing is added automatically — you choose what gets pinned.

• Manage favorites from Edit > Preferences > Add-ons > Color Space Converter:
  • pick any colorspace from the dropdown and click Add to Favorites to pin it;
  • click the ✕ next to any favorite to remove just that one;
  • Reset Favorites to Default clears the whole list back to the original five.
• Favorites persist across Blender sessions.
• If Blender's OCIO config can't be read for any reason, the dropdown falls back to the original five profiles (sRGB, Non-Color, Linear Rec.709, ACEScg, ACES2065-1).
