Adding a Sky to your first room.

This is a continuation of the first room tutorial.

Add the false detail brush and box containing your world.

Check it, we 'bout to be about this beoctch.

Alrighty, so you need a false detail brush in your level. According to the docs, it should be a concave brush containing your level. Well- make a box, drag it out so it contains your level, flip the texture to the inside and put the blocker texture on it. The blocker texture is in the TEX root folder.  Bring up the project window, click the properties tab, change Type to BLOCKER and Lighting to flat.  Change the Detail to False.

Start by creating a cube 256x256x64. Place it flush with your ceiling in the first room.

Make a hole, joel.

CTRL + G , mouse over, Page down.

And it's gone!

CTRL + B, hit F to flip the texture to the inside.

Fix the ceiling.

Our stupid ceiling needs a stupid hole now. 

Since there is a brush there already, no sense in deleting it. Make your ceiling into one of the triangles we need for the new holy ceiling.

CTRL + G, hold M and LMB (Left Mouse Button) drag the corner to the edge of the skylight hole.

Concave brushes are not allowed. Picture a spoon. There is no spoon.

One of the triangles is now complete.

Now fill up the rest of the holes with triangles using geomode to create. Remember if your texture is on the top, switch to brush mode (ctrl +B) and flip the normals (F)

Some times you just got to say "damn that's cool!" Notice the vertices all touch.

Now select the skylight section and un-join it (ctrl +J)

Select just the side 4 faces and rejoin them (shift +J) leaving the top polygon un-joined.

Select ONLY the top polygon, bring up your project window and in the TEX root folder select the SKY texture.

HIT CTRL + T to paint it SKY.

Now select properties of this brush and change the type to Skyportal and the lighting to flat.

Place the marker (x) outside and below your blocker false detail containing box.

Click on the prefabs tab in the project window.

Choose the global folder and add one of the various skies.

(double click)

Save and process your file.

Run it!

A sweet foreboding sky!

Now wherever you place a sky texture (with skyportal in the properties) in your level, it will show your nice sky.
