Bug Description

Version: generals-weekly-2025-10-17

https://github.com/user-attachments/assets/eae6f114-db3d-4221-8c54-c6ac282389b5
This is a footage from USA campaign at the very start of it.
The terrain under the bikes won't render at all, and bikes will fly mid air.

i also saw this behavior in Vanilla generals (the same weekly version) in training while the helicopters are flying, but didn't take footage of it.
also in the first mission of china after the tanks cross the bridge to reach gla, a footage will play where the terrain doesn't render.

Reproduction Steps

Zero Hour:

1. Start new campaign in Generals:ZH USA.
2. wait for the scene of Motors coming off the mountain.

Vanilla generals:
1.Start a new campaign in Training.
2. wait for the scene where the ground is not rendering.

I think this happens with non 4:3 resolution? Terrain Height Map has bug where drawable terrain origin is not where it should be.

I think this happens with non 4:3 resolution? Terrain Height Map has bug where drawable terrain origin is not where it should be.

Setting resolution to 800×600 fixed the problem, yest it seems like this is the case.
