I have noticed that opacity seems to work a little as “flow” : that is to say if you use a brush, with, let’s take an example, opacity set to 50%, if you draw twice on the same spot, then you will have an opacity more than 50%.(less than 100% though, so not like a flow set to 50%).
Should opacity change when you draw the same spots more than once ?
Thanks for your advice
