Title: Tilemap affected by light
Post by: deathbypixel on November 26, 2012, 10:04:50 pm

Hello and thanks for a fantastic product!

I have created a tile map in a scene (I'm using a perspective camera) and I'm wondering what approach I should use to get my tiles affected by light, e.g. with a spotlight.

Cheers!

You will need normals for this to work...
in tk2dTileMap.cs, line 132, comment this out so it reads:

Code: [Select]

// if (tileMap.serializeRenderData)
chunk.mesh.RecalculateNormals();

Now you should be able to just switch to a lit shader and lights should work

Thanks, worked perfectly! Note that this was in k2dTileMapMeshBuilder.cs

How will this affect performance?

Shouldn't be any worse. It takes longer to actually build the tilemap, but if you're not modifying it at runtime, you shouldn't need to care.
