A simple OSL tutorial aimed towards painters looking to start with OSL.

The lightsource

  1. Basecoat the lit areas with Corax White
  2. On the very brighest spot, apply a layer of White Scar
  3. Wash with Tesseract Glow . Dont use too much, as it can fill up recesses.
  4. Create a mix of White Scar with Tesseract Glow . Gradually build up to white as you layer towards the brightest spot of light.
  5. Finish your source by applying a small dot of White Scar on the brightest point

The Glow

  1. Stipple a brush loaded with Tesseract Glow onto a piece of tissue. We want to get rid of the water, but keep the pigment onto our brush.
  2. Once you feel like you can control the Tesseract Glow on your brush, glaze or stipple the edges near the lightsource.
  3. Repeat this step to build up a glow you are comfortable with.
  4. Finally, take some mix some Tesseract Glow with White Scar and stipple it once again on a piece of paper. Very carefully drybrush the edges closest to the lightsource. Dont be too clean, as a clean line would break our gradient.

Extra tips:

1) Light fades quickly, especially on black. An edge will always be far brighter than any flat surface
following it.

2) Don't worry about messing up. Our necrons are rusted, broken and beaten. The messier and rougher they look, the better our effect

3) When placing the final white dot, think about the position the model will looked at. The brightest spot is always the closest part to the onlooker. If the model is for gaming, then it should be towards a higher spot. When looking down at the model, the white dot will be closest making the OSL illusion work best
