Mmm.. I think the same.
As you know, there are some script to change randomly maps value?
I've a multi/sub obj material, with 20 CoronaMTL inside, with ColorCorrection in the diffuse and the same diffuse texture for the 20 material.
I would like to change automatically the ColorCorrection HUE ans the Saturation automatically, and not change manually for 20 sub-oject (for 10 different Multi/Suvb obj) =(
