[Help] Creating a light vector from blueprint?l [Cel Shader]

[Headstub]

You’re on the right track by placing the light vector in a parameter collection. You don’t want to replace that with a blueprint: you want to update that vector parameter from your blueprint instead.

Take a look at the skysphere blueprint that comes with the engine, this uses a similar approach to transfer the sunlight direction.

If you want to have your shader influenced by multiple light sources you have to add multiple light vectors and a weighting factor to you parameter collection.

Finally note that this approach won’t really work with shadows at all.

Alright, thanks! I will try it out.
