An extremely easy trick to get 3d stroke in photoshop.
Well, most of you must heard about this, in case you don't, is something really dumb to do but is absolutely cool, here's how:
You can try with soft brushes, as I said before, I only use soft brushes in extremely necessary cases like shading an entire section, backgrounds, ambient occlusion, and others, I never use soft brushes for details, but that dependends on the style you want to get.
Right click on the layer that you want the effect > Blending Options > Bevel & Emboss. it is important that the stroke is isolated (by this I mean that the stroke should not occupy too much area, since the effect is only visible in the outline of each stroke).
Yes, I know, that screenshot is in Spanish; Sorry about that, Blending options should be in the same place. But come on guys, it's 2018... almost everyone here knows about Blending options right?
In the section "Structure" select Technique > Chisel Hard, try to adjust the values to get the effect you want and that's it!
If you are wondering how strokes looks like this? You can download thousand of brushes on internet and try until you are satisfied with the result. Soon I will be posting the set of brushes that I used in this illustration.
HAVE A GOOD ONE and sorry for my horrendous english. :D
Cool trick! A mix of both arts, digital that looks like traditional. I'd like to try this trick eventually~
Try it! and if it doesn't work, just turn off those layers style, it won't compromise your artwork at all
