Hi Daniel, After showing waters, can you restore the desired appearance with "light soft shad f" or "light full shad f"? I'm guessing no... Other guesses are that it's either a graphics bug or some of the waters are extremely far away in the back making the visible scene dimensions change drastically, changing the position of the depth-cueing ramp and other lighting-related calculations. One reason I thought of scene-depth change is that the silhouettes are shown when the objects are some fraction of the total depth apart, and in your after-water pictures, there are many fewer silhouettes, suggesting the overall depth is now huge. See "graphics silhouette" <https://rbvi.ucsf.edu/chimerax/docs/user/commands/graphics.html#silhouettes> However to really figure it out we would probably need to you use Help... Report a Bug and attach a session that exhibits the problem. I hope this helps, Elaine ----- Elaine C.

Hi all, I have a few maps and models loaded, which have a couple hundred water molecules. When I display all the waters using 'show :HOH' the lighting changes. It makes "soft" look like "flat" and creates what looks like more ambient reflection in "full" or "simple." I embedded some screenshots below.
My guess is something about a depth or lighting calculation is affected by all the waters, does anyone recognize what setting would need to change to correct this?
Soft, shadows false: <image.png> Same after show :HOH <image.png> Full, shadows false <image.png> Same after show :HOH <image.png>
