Isometric Draw Order Problem

[boehmz]

In an isometric view, when a small sprite goes far away enough from the camera from a larger sprite that it's supposed to be on top of.

The main character gets drawn underneath the floor at the back here:


But in the editor, moving the camera to a side view shows he's clearly on top.



Basically I want to order draws by y-position only(I think, maybe there might be some weird exceptions case even with that).  I'm using orthographic camera with rotation of 45,45,0 euler.

The whole tilemap will be drawn in one draw call - so you'lll have to make sure your character is in front of the whole object, not just the few tiles there. Easy way to tell is to select the tilemap mesh and look at bounds.

Seems like a tricky problem.  We want our character to be able to walk to the back of an object and still be on top.  Currently we kinda hack it by putting the floor objects way below(since it's orthographic, and camera angle doesn't change).  Any tips you can think of to get around it through shaders or any other draw settings?

Couldn't you can use tilemap layers to help here? YOu could put the foreground objects in a different layer to the background and then move your character in front of or behind them.

Even when making layers of tiles, the lower layer sometimes gets drawn on top when viewing the tilemap not completely top down.

That is an example of a tilemap with all red tiles on the top layer and all blue tiles on the bottom layer.  At about halfpoint, the blue tiles get drawn on top of the red tiles.

I'm fairly fluent at rendering techniques, what files handle the batching of draw calls?

Nevermind, was replacing the tiles with prefabs.  I think I got this all worked out.
