Using normal map on TileMap

Hi! So I've been trying to get into normal maps. I can get them to work fine on regular objects, but I'm having some trouble making them work on my TileMap. I have 5 different spritesheets thats spread around on different layers. I've tried making it work, but I only found this 2D-TechDemos, but when I try use the shader that comes with all the normal maps just comes and go and is put on the wrong tiles.

Anyone got this working?

 

Ok, thanks for the reply! Love to see that the developers are so active on the forums! Guess I'll just use normal mapping on my regular objects for now and wait for this feature to be released!

 

Isometric tilemaps + Chunk + Overdraw creates over-bright blotches where the overdraw exists. Is there a way to address this either with the shader or tilemap setting? It's extremely time consuming to produce isometric assets that don't result in any overdraw. Example of what I'm experiencing with exaggerated overdraw:

 

Thank you, I'll try that out.

Using: standard sprite diffuse material (the TechDemos normal shader does the same thing).

Before applying CustomOutline and turning off exaggerated overdraw:




Here's the sprite on from the spritesheet tightened up w/ Custom Outline:




Result with tightened up CustomOutline:



For demonstration, spikey-shaped Custom Outline:


Result with spikey shape - note how only the second spike produces over-bright area, not the first spike.


Problem as far as I understand it
Tilemaps + Chunk mode + normal/diffuse + it's hard/impossible to have zero overdraw when making isometric art to my knowledge. I tried for quite a while to get the Custom Outline shape right, but it would always produce artifacts somewhere. The tilemaps seem to multiply the power of the normal map where overdraw exists, though I'm not totally sure what's the issue. Even if there was a good workflow for dimetric or true isometric tight meshes (I'm use true isometric here), many isometric tiles would benefit from being able to draw into a neighboring tile without creating these over-bright lines.

Some questions
Could there be some kind of shader solution? A tilemap setting? Why do these bright lines appear w/ chunk but not individual mode? Could there be a setting to tell the tilemap, when chunking, to not combine the power of the lighting in areas of overdraw, but rather only write what's on top according to the Sort Order (Top-Right, Top-Left, Bottom-Left, Bottom-Right)?

 

You could also use TexturePacker for this and follow this tutorial:

Worked fine for me.

 

Wonderful! It works like a charm. Thank you so much!

 

Is there a way to get chunked tilemaps with normals to respect X-Mirroring?

Code (CSharp):

1.    
2. class MirrorableTile : TileBase
3. {
4.     public bool mirrorX = true;
5.     public override void GetTileData(Vector3Int placementCell, ITilemap tilemap, ref TileData tileData)
6.     {
7.         // other stuff
8.         tileData.transform = !this.mirrorX ? Matrix4x4.identity : Matrix4x4.TRS(Vector3.zero, Quaternion.identity, new Vector3(-1f, 1f, 1f));
9.     }
10. }

The lighting from normals get inverted for me if mirrored w/ chunked tilemap
