Shaders can be mathematically generated - no visible texture until rendered.
Lightworks can use shaders, alone or in combination with textures.
Textures are images. The internal engine uses textures.
The only way to get a shader-like image into the internal engine is to somehow make a rendered image of it and then capture that image, using it to make the internal engine texture.
We do this by rendering a softly lit wall - say 1mx1m for easy sizing - and taking a screenshot of it.n NOw you have a texture for the internal engine.
Viola!!! Bassoon!
