Edit lightmaps in Material / Shader?

Development Rendering

Hi!
I’m wondering how to call lightmaps generated in UE4 in a Material graph to play with them and edit/process them ?

Thanks

You sort of can… Lightmass gives you the option of baking an AO mask, if you do then you can access that in the material editor via the “PrecomputedAOMask” node.

But for the actual light/shadow maps as far as I know that requires adding a new shading model, which isn’t done in the material graph.

Indeed I’d have loved to reuse Shadows GI maps etc…
Too bad the only way seem to do your lightmapping and compositing by hand (baking outside ue4?)

That would probably work but I would not recommend that. It might look fine for static scenes but you’d have to come up with your own solution for lighting movable objects because you won’t have the Volumetric Lightmap.
