Iwo Jima Blue Spawn Graphical Error

[Pat]

I get this every time I look at the ocean at Blue Spawn on Iwo Jima.

If it's necessary to know my computer specs, I can follow up on this post.

It's known. Unfortunately there isn't an easy way to blend water from inside the level to water in the 3d skybox. I have searched around and the only solutions I have found are 1) make the playable area, where the water is, so big that the player wont be able to see the seam, 2) block the seam with props.

I've decided to add some extra information on getting your skybox just right for various situations. Skybox scaling can be very finicky: sometimes you'll notice that the scaled down stuff is off the grid, thus preventing you from lining up your skybox stuff properly. The most commmon area where this is a problem is the creation of seamless water. Here's a way to do it that can save you strife.

1. Create your map as usual and add your water brushes. Follow the tutorial up to the point of adding your extra brushes.

2. Most of the time, your water brushes will be off the grid, so you won't be able to add the seamless bits without screwing everything. There's two things you can do here: you can either hold down alt while aligning the new brushes, which'll disable the snap to grid settings. You have to be very precise, however. The second method, which is a little harder but more accurate is to resize the water brushes in the 3D skybox so that they're on the grid. Try and match it to the exist shape. After you've done that, select the water and scale it up 16. Take this scaled up version of the water and place it into your map, making adjustments to the skybox where nessecary.

3. Now you'll be able to make seamless water! As an added precaution, copy the water in your map and the sky_camera again and scale it down, just to make sure everything's aligned.

its not a matter of brush alignment, its cubemaps and reflections
