has something changed in the way the Octane plugin reads the diffuse texture gamma from AC materials in AC25?
in a new AC25 file all diffuse textures have gamma 1 and look washed out, and then i checked some old files in AC24 and the value is 2.2 for all materials.
i tried to reconvert all materials but it's still the same, and if anything i made things worse as the materials i had personalised now need redoing...
any ideas?
