So, I recently came across this allegorithmic section showing how you can paint flowmaps in substance painter:https://support.allegorithmic.com/documentation/display/SPDOC/Flow+map+painting
I need to do flowmaps for hair at work so this seemed like a great way to do it. While I am happy with the results, there were a couple things that bothered me and since I am a novice at SP, I was wondering if anyone had ways to make this easier. I'll start by describing how I did it.
My basic workflow was to paint flow for a set of strands, start a new layer, do more strands on top, new layer, more strand on top, etc. I did them as groups of strands to speed up the process. For one set of cards, I usually ended up with 4 or 5 layers. You can tell that in the normal channel, they blend together instead of layering which doesn't work for me so I had to export each layer separately, and then layer them in photoshop. That was issue #1
...is there a way to get them to layer in SP in the normal channel? Issue #2
is that each stroke had a border of the default normal value around the stroke. I don't know if there was a way to remove this but essentially, I had to erase that from every layer I exported in photoshop. As you can see, doing this for every stroke is a major pain in the ass. I'm just curious if anyone more experienced with painting flow maps in SP can help me out.
Thanks in advance!
