@ThatAudiFan For better visibility I've been playing about with blend modes, etc and have ended up with the following settings:
To group 'PRO-AM Group' (as I'm using blue leds for the N24 number boards):
- Blend mode of group to 'Linear Dodge (add)'
- Inner glow: blend mode='Linear Dodge (add)', Colour=white, opacity=29%, noise=71%, technique=precise, choke=52%, size=5px, contour=(the one that peaks in the middle), Range=49%, jitter=0, anti-aliased=checked
- Satin: colour=white, blend mode='screen', opacity=18%, angle=45,distance=33,size=16contour=(the one that peaks in the middle), anti-aliased=checked, invert=checked
- Inner glow: blend mode='screen', Colour=(same blue as the led parts), opacity=94%, noise=16%, technique=softer, spread=49%, size=8px, contour=(the one that goes diagonally up from left to right), Range=100%, jitter=31, anti-aliased=checked
LEDS DIFFUSE layer (this is the main one I found to make it better the most):
