Accurate lightmap on a masked material

Development Rendering

Hello,

I’m a bit new to lightmaps and I still got some troubles to use them efficiently.

Here is a material I’ve created that uses a really dense transparency mask :

Is there any way I can bake proper shadows for objects using this material ? Dynamic lights gives great results but I’m trying to gain performances here.

Increase the Lightmap Resolution of the Floor.

Ho… I was increasing the lightmap resolution of the grid.
I get it now, thank you !

The Lightmap of the Shadow Receiver determines the Shadow Resolution (in case of baked lighting), not the object itself.
