Sakura

I created both the pavement and sakura substance in Substance Designer completely procedurally. Making the sakura petals was rather straight forward. What required some attention was the height channel, as it needed exposed adjustment in order to be able to blend to other materials seamlessly in Substance Painter.

I also made sure that the outputs have instructions for Substance Painter with tag "blendingmode=normal" as otherwise this would require user to change the settings to match. I have also created a switch to disable height channel.
