Windows 10 Pro, 64-bit.
Short description of error
I model various assets and texture them with Substance Painter. In order to upload the models to Gumroad etc. I choose "Automatically pack into .blend" and pack all the textures and HDRI inside the blend file. When this file is opened again in its packed version, then when I press Shift+Z for real time rendering, then the models appear strangely glossy or with surface artifacts. I searched a bit and I found out that the problem lies in the node editor's properties panel on the right (N key). Despite the fact that all image texture nodes for roughness, bump and normal are set to "non-colour data", the properties panel keeps the "sRGB EOTF" value and makes the packed textures appear strange. The problem is solved in two ways:
- Change the value to non-colour by hand, or
- Unpack all textures to a new file.
I upload a PrtScn with a red highlight at the problematic areas.
