[Music] Hi everyone and welcome to this video
where we'll be showing you this exciting new update in Substance 3D Painter.
This is the 3D paths tool and this allows us to create brush Strokes directly on our
model using editable curves. What's cool about this tool, that's different to using the regular
paintbrush tool is that we can dynamically change the brush's properties even after we've created
our path. We can select a different brush, adjust the size,
change the material properties and much more; this is a completely non-destructive workflow. We use the 3D paths tool on paint layers,
either on a regular paint layer or in a mask. You can paint, erase, and smudge using the paths tool. You'll find it located in the top left toolbar just below the eraser. The purpose of this tool is to be able to
paint with curves around our meshes geometry, so we will only need the 3D viewport for now. Just to note, this tool currently does not work
with some of our 'Tool' brushes, which you can see here, this is because they are already tied to
the original Paint, Smudge and Erase tools. There are however some new tool brushes, made especially
for 3D Paths, that we will look at in another video. Right, let's jump into it! To start creating a path,
I first make sure that I'm using a Paint Layer. Then, I select the Pen icon for the 3D Path tool. I then begin clicking to add 'points' or 'vertices' along my path. You can see that when I begin creating my path,
I now have this small dialog in the top left of my viewport. This kind of works like a layer stack for my paths where
I can visualize them and select which one I want to work on. But more on that later! By default, the point interpolation is a smooth automatic bezier,
but if I want to change it to linear, I can double click the vertex to make it a sharp corner. Another way I
can do this is by selecting a vertex and clicking this icon in the top toolbar. Using this method
I can click and drag multiple points or Ctl/Cmd + A to select all the points and then
convert them all to corner points at the same time. The same approach can be taken if you want
to delete multiple vertices at the same time. Just click and drag and then press 'delete' on
your keyboard. Currently we cannot edit the bezier handles. But what we can do instead, is add in more
vertices in between our existing ones. To do this, all we need to do is hover over an existing line
and click where we want our new vertex to sit. Don't be afraid to add lots of vertices,
particularly if your model has quite complex geometry. Once you're done creating your path, you can complete your
path creation by pressing the 'Esc' key or the 'Enter' key. The next time you click on your object
you will then begin making a new path. You can have multiple paths on one paint
layer and as previously mentioned, we can visualize these different paths in the Paths window in
the top left of your 3D viewport. Here we can right click to copy, cut, paste, duplicate, and remove
paths as well as double clicking to rename them. Now, let's take a look at the toolbar at the
top. Some of these properties you will recognize from the regular brush tool, but let's talk about what's new! This first icon toggles a display of the curve and vertices overlaid on your path. You can also toggle this visual display with the 'Q' key. This next icon opens a display window where you
can adjust the way your path is visualized on your geometry. This button can reverse the direction
of which your curve is being created. This can be helpful if you want to continue your path
from the other side. Next is the pressure slider, this essentially adjusts the size
of your brush on a per Point basis, you can either adjust a single Vertex or multiple
at the same time. We've looked at this icon previously this is the vertex interpolation toggle. You can close and open your curve by having an
end point selected and clicking this. This button is the same as using the 'delete' key. You can switch on symmetry for your paths
by clicking the mirror icon and this can be toggled for each path that you create within
your layer, so you don't have to have all paths being mirrored if you don't want to. You can adjust
your mirror properties with the buttons next to it. Each path has its own brush and
material properties. If you want your paths to share the same material
properties you can use a fill layer, with a black mask and then add your 3D
Paths to a Paint layer within that mask. If you add vertices quite far apart you
may see that you lose some of the paint. To fix this you can either put an extra vertex in the middle of these points, or adjust the projection depth in the properties panel. We hope this new feature helps accelerate your
texturing workflow in Substance 3D Painter. We can't wait to see what you create!
