I tried adding lights in WED and they didnt show up at all when running the game. So how can I create lights for my plane?
I checked both the colour and the range of my lights and still couldnt get it to work. An example/demo of lights would probably work as well.Thanks a lot and btw I use 3dgs 7.86 PRO!

For this type of lights including lights in WED only doesn't help you at all. To make lights that are in place of plane (like on the wings) you need to make lights follow certain position at the plane (or certain vertex).

Why the lights didn't show up at all in the game I have no idea. I can only quess that you have A) put them inside a block/model or B) their lightrange/ambient is around 0

However, for the plane lights I'd guide you to use ENTITY as your lights made in the plane action. Then these entities would have a function that'd made them follow plane. That's at least how I'd do it.

Do you need them to glow, or you just need them to shine in lightrange?
It you need them to glow, then you need to attach bmap with glow, on vertexes (or bones) of your plane.
You can also make them shine by increasing they lightrange.
For attaching entities to vertexes look for 'vec_for_vectex' (or 'vec_for_bone') in manual.

When you place light using WED, the default is(i think) it's a static light which only affect static shadow on blocks. Even if you create it as dynamic light, it wont move along your plane, so you must create it as light emitting entity.
