HDRP - How to have the same Material/Shadow colors on MonoBehaviour and Entities

Hi Everyone.

I'm trying to do a very complex task on Unity: Render a white cube on a white plane (a real one, with no an ugly gray or pushing emission to max to have an white heaven effect.

I started with UDR but I found that UDR isn't compatible with and ECS and Ambiance color (yeah !)

So I restated my project on HDR and play for hours on Light Settings (spread everywhere on the project), to get a good mix between "white" and contrast (depending to face light exposure)..

This is the best I can do, It's not even white (but more around 200/255) to have a minimum of contract between faces.

Settings: (Left image)

• From original HDR Example
• Directional Light - Emission Filter (128,128,128,255) / Temperature 6750 | Intensity 10000
• PostProcessing - WhiteBalance -Temperature 0 / Tint 0
• PostProcessing - Default HDRI Sky - Exposure 10
• HDR - Ambiant Occlusion - Intensity 0.5 / Radius 1.5
• HDR - Tonemapping - ACES
• HDR - Bloom - Intensity 0.2
• Player - Color Space: Linear

Unique Material:

• HDRP/Lit
• Base Map: (255,255,255,255)
• Metalic: 0
• Smoothness: 0

Still don't know from where I got this awful blue tint on shadow or right Image (when I put the Emisison to (0,0,0,255) on Directional Light..) Level of Gray, or even black okay.. but blue ?



--- Now the fun part ---

I used this tutorial (github code) in order to spawn MonoBehaviour prefab (the same cube with the same material). Note that I got the same result by creating the cube entity manually.

And voila... 2 completely different cube again, and the entity is not even close to white.



What did I miss... ??
Please help, it's been a week...
