[SDK 3.8.1-beta.3] - Toon Standard can appear overly bright in some worlds
available in future release
まかべちゃん
Compared to ToonLit, the new Toon Standard shader can appear significantly brighter and may easily blow out highlights.
While it looks fine in darker environments like the Unity editor or the default home world, it can sometimes appear too bright in other worlds.
I’ve attached a screenshot taken in this world:

Unity上や、デフォルトホームのような暗いワールドでは問題ありませんが、他のワールドではかなり明るく見える事があります。

This issue can be divided into two problems.
The first is that there is a difference in Light Probe brightness between the two shaders. Toon Lit calculates the average (which is actually slightly different), while Toon Standard calculates the brightest point, so there is a difference in brightness. I think this is as specified, but I think it would be appropriate for the two shaders to have the same brightness to increase the sense of immersion.
The second is that the brightness of Toon Standard exceeds 1.0. This shader adds a clamped directional light and a light probe. However, the result of adding the two is not clamped, so the brightness will exceed 1.0 and spoil the appearance of the texture. I think this user wants the result of adding the directional light and the light probe together to be clamped.

lilxyzw: That does make sense, thanks for the investigation!
The brightest-point sampling is indeed intentional, as it tends to give a more toon-style shading in our experience with worlds. I don't expect that part to change.
Clamping the final result instead of the intermediary light calculations might make sense though, and probably solve this issue for most cases. I will look into that!

I’ve attached an image of the material settings used.
Even when I reset all settings to their default values, the shader still appears overly bright in the same world.
Let me know if more information is needed.
materialの設定も画像で添付します。
なお、全ての設定をリセットしデフォルトにした場合でも明るい事には変わりありません。

まかべちゃん you using the shadow tint at value 1 and shadow boost at 0.3, what do you expect, try lowering it will fix the issue

Dexxxxxxx As I mentioned before, even when all settings are reset to default, the brightness remains unchanged, so the shadow settings are not relevant. I only attached the material settings just in case. Also, for the record, the emission settings have nothing to do with it either—just to be clear.

Dexxxxxxx Since you asked what I expect — ideally, I’d like the brightness to be at least closer to ToonLit, because the current Toon Standard is simply too bright. In fact, even ToonLit tends to blow out highlights easily, so it would be best if the shader could avoid overexposure more effectively.
