A Dirty Little Robot, Part 3 - Substance Painter

WOW! Look at that color!

That's right, I selected parts of the mesh with the 'Polygon Fill' tool and made the front bumper-bar-thing pink. As well as painted on some additional pink decorations by hand, and added some green undertones by masking off some parts of the model, and dipping the whole thing in a green Fill Layer.

Not to mention I exported the whole thing into a smart material, and slapped it onto the legs! Whoa cool!

Also I learned how to scrape some detail into the mesh using Normals, with 'stamps'. Or something...
Here's how to ... Stamp with Normal Maps
  1. Make an empty layer, enable ONLY normals in its Properties 
  2. Delete any alphas that might be on its brush
  3. Go to the shelf and select Hard Surfaces
  4. Drag one of the 'stamps' onto the Normal in the Properties panel
    1. Protip: if you are using a touch-tablet, disable pressure
    2. Protip: Ctrl + Left-Click + Drag Up and Down to rotate the stamp
    3. Protip: Ctrl + Left-Click + Drag Left and Right to change Flow
    4. Protip: Ctrl + Right-Click + Drag Left and Right to change Size
Also, Using a Stencil to Paint Through
Usually you have to import the stencil, which is a black and white image with the desired 'stamps' or other details on it.
  1. Select a map which you wish to stencil through
  2. drag and drop the stencil onto the 'Stencil' bar in the Properties panel
    1. Protip: S + Middle-Mouse Dragging moves the stencil sheet itself
    2. Protip: S + Left-Click Dragging rotates the stencil sheet
    3. Protip: S + Right-Click Dragging scales the Stencil Sheet
    4. Protip: Rotate  while hitting Shift will snap it to closest 90 degree angle
  3. When you are done using the stencil sheet, 'x' it in the Properties panel

Get Emissive...Adding some glowy bits
  1. Go into the Texture Set Settings
  2. Add an Emissive Channel [pic included]
  3. Create a new folder
  4. Add a Mask by Color Selection to that folder
  5. Click what you want to be emissive, and add a Paint Effect to the folder, use the Polygon Fill Tool to select what else you want to include
    1. Protip: Alt + Click on the mask to make sure you selected the right things
  6. Create a new empty layer to paint on, and drag it into the folder
    1. Make sure the Emissive channel is the only channel enabled in it
  7. Choose pure Black and start painting
  8. After painting, go to Viewer Settings and and lower the Environment Exposure to a small negative number, like -2 for example
  9. Add an Effect and choose 'Filter' [This is still on the layer that you are painting on]
  10. Click on the Filter Tab and search for 'Gradient', click on the icon when it appears
  11. In the gradient's parameters, make Color 1 a lighter hue of Color 2, for example, red
    1. Color 2 should show in the spaces you painted
  12. Paint over the same areas with pure White
These should show up in a render
