The camera is at (15.5,-15.5,5) and the image map shows: green trees at top, cabin (W block) center-left, and a big bright region (#/+) bottom. The bright region spans the bottom half — that's the pond area. But it's bright (#) rather than teal — the water isn't showing as water.

Wait — I notice the bright region has no 'b' (blue) characters at all. The whole bottom is bright warm (#/+) which is the sky reflection? No — from this camera the pond reflects the sky. The sky at the horizon is warm (sunset), so the reflection would be warm-bright. The pond water reflecting the warm sky would look bright warm — which matches the #/+/= region!

But my pixel samples at the pond locations showed 0.42,0.37,0.30 — that's not bright warm. The pond center NDC (0.67,0.2) — in the map, row ~28 (of 40), col ~25 → that's in the '=' region at the bottom-right... The bright # region is lower-left.

Let me check: maybe the pond is actually at the lower-left bright area, and my sampled "pond points" are hitting the ground because the pond center (8,-7) projects to a different place than I think. Let me re-verify with a bigger sample and check whether the water is visible anywhere. Let me sample the bright region.
