A tick box in some of the materials layers to invert the map being used would be quite handy. This is especially true in the opacity slot (some vendors supply opacity maps inverted), however it would also be useful in the reflection, bump and probably the translucency layer as well.
As far as i know there are two ways to invert a map within c4d, and both of which are quite tedious (especially when doing many plants, for example). A simple tick box to do this would be appreciated.
Thanks,
Brad
