Good morning,
I've posted recently on my instagram a quick tutorial how to paint a fire effect.
I think it is a good idea to have it here on my blog as well:)
Step 1) White basecoat applied with airbrush from above.
Step 2) Orange basecoat and white wash in recesses
Step 3) yellow applied from airbrush
Step 4) yellow + white mix wash in ratio 1:1 just in the area of the source and
edge highlighting the nearby areas
Step 5) Darkening the upper parts of the flame with pure black and dark red
paint.
That's all, really fast and effective way to achieve quite realistic fire
effect with osl.
