Hello @BryonyRae
Apparently this is by design, for performance reasons.
Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Often (50% - 99%)
What is your current game version number? 1.65.70.1020
What expansions, game packs, and stuff packs do you have installed? Seasons Cats and dogs Vampires Free holiday
Steps: How can we find the bug ourselves? Place seasons items in a room
What happens when the bug occurs? Items are too shadowy
What do you expect to see? Visible furniture
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure
A problem with seasons that I have had for a long time is the shadows on some objects. When you put them in a room they are very dark. This does not seem normal to me since I did not have this problem with any other pack...
Glitchy items:
Happy H-all-idays Banner garland
Seasonal card display
Surfaced Succulents
Branching out
Tired to simplicity plant
Winter wreath
Just in case no one ever responded to this, I have the same issue with most of these Items. The Tiered to Perfection object doesn't look that bad. Everything else listed has pretty apparent lighting issues. This includes the five items on the wall stuck in permanent shadow, and the potted plant stand to the lower left. To show contrast, I left the other wall item and the pots on the right in the picture.
