Unity Issue Tracker - Tilemap Tiles do not get lit up unless the Light Range is greater than the distance between the position of the Tile before the transformation and the Light Source when the Tile is transformed with Tilemap.SetTransformMatrix method

The TilemapRenderer generally works on the XY plane and has a flat XY bounding box in 3D space. The TilemapRenderer can be culled from 3D lights if there is a large Z difference from the light itself. Setting a Transform matrix for a set of Tiles does not automatically increase the bounding box for the TilemapRenderer. To help with that, you can make use of the "detectChunkCullingBounds " and "chunkCullingBounds" properties of the TilemapRenderer. You can set the "detectChunkCullingBounds" property to Manual and increase the Z value for the "chunkCullingBounds". This will prevent the 3D lights from culling the TilemapRenderer when rendering the lights.

How to reproduce:
1. Open the “TilemapLightingTest.zip” project
2. Open the “SampleScene”
3. Click on the “Point Light” GameObject in the Hierarchy
4. Enter the Play Mode
5. Increase the “Point Light” Range to 7 (or the distance between the light and the Tilemap Tile)
6. Observe the Game view

Expected results: Tilemap Tile is lit when it is within the range of the “Point Light“ after the Transformation
Actual results: Tilemap Tile is lit only when the range of the “Point Light“ is set to a greater value than the distance between it and the Tile

Reproducible in: 2021.3.36f1, 2022.3.21f1, 2023.2.14f1, 2023.3.0b10

Reproduced on: Windows 11 Pro (23H2)
