I’d like to be able to use basic layer modes such as ‘add’ and ‘multiply’ when stacking multiple bump texture layers. If I create a base bump layer and then create a new one on top of it, the interaction between the layers starts to cancel out the effect. If I was able to set the top layer to ‘multiply’ than I’d be able to blend the two layers more naturally. I noticed that there is a ‘mode’ tab that can be activated by right-clicking over the Name/Opacity column, but it doesn’t allow you to change it (nor is there any mention of it in the manual).
Any ideas?
