P: When importing 16 bit mode psd into the AI and ID, group with layer mask will not work properly

[K_C_Alvis]

Everything will be okay in 8 bit mode.
However, when using 16 bit mode, importing psd into the AI and ID, if there is a group of layers inside a transparent background PSD (no solid colour there), group with layer mask will not work properly, especially the opacity function of those layers inside the group. Without layer mask or not, the opacity of the layers inside the group is totally different. It seems, the calculation of the opacity getting error when there is layer mask even it is white with nothing!

I got more detail now: if a group of layers only contains some adjustment layers like solid colour, etc, the problem happens.

Can you post a sample file that exhibits the behavior? (dropbox/CC files and post a URL)

I sent you an email. I'm not seeing a rendering difference.

Try this: Go to Preferences > Performance... and check "Legacy Compositing" - open the affected file and re-save it and update in AI or ID, does it look correct?

I've asked engineering to look into this.

This issue should be fixed in the current version, Photoshop 2020 v21.x or later. Let us know if you're still having trouble.
