Make a hallway with a door at each end to connect the sky boxes and put a areaportal brush in both doors that fills the door but is thinner than the door so it is inside the door it can overlap the structural brushes around the frame though .
Well I tried to build your idea several different ways, but could not find one that would work. The area portal idea seems to be the best advise. Unfortunatly I have no answer for this one.
You don't know what what means ? you don't know how to make a brush with the areaportal texture on it and fill the door frame with it ? It should be thinner than the door if the door is 4 units thich you make it 1 or 2 units thick . There is no func for this you just put the texture on the brush and seal the skyboxes by putting an areaportal brush in the doors. The reason I said to connect the two skyboxes with a hallway is if you just put a door between two skyboxes as soon as you open the door both skyboxes will draw but if you use a hallway only one of the boxes will draw when the door is open as well as the hallway and when you are in the hallway and the doors are closed only the hallway draws . You see only when the door is open is the portal open this is good for vis too .

Make a shader and put the shader in the scripts directory and make a purple.tga and put it in the textures/models/natural/ directory or put them both in a .pk3 in those directories .
How are you going to learn if you give up ? I gave you all you need to know . Just pick a tree or bush find the tik in pak0.pk3 copy the tik and rename it . The part you want to change is the surface because you want a purple color for it . As you see in the example I gave you the surface has a shader and the shader has the info as to what texture to use for the tree . In this example the surface is called wshrub and it uses a shader that I named static_purpleshrub .
surface wshrub shader static_purpleshrub // change shader here
If you open scripts/trees.shader from pak0.pk3 you will find the shaders for most of the trees . So find what shaders the surfaces of the tree you picked use from the tik . Let me give you another example . Open pak0.pk3 and go to the model/static/natural directory and find the tree_winter_fillpine.tik
As you see it's texture is tree5s_1.tga all you have to do is find that texture in one of the other .pk3's and edit it to make it purple simple is it not . Then all you have to do is give your edited .tga a name copy the shader into notepad and use your textures name save the shader not as a txt file but as a myname.shader file then copy the .tik and where the surface is put the shader name for your .tga instead of the shader that was there .
Thats it files: .tik .shader and .tga's
Make a .pk3
tik goes in the models/static directory
shader goes in the scripts directory
tga's go in the textures/models/natural directory
all the shaders for the surfaces can go in the same myname.shader file the same as all the tree shaders where in one file .
The last thing you can do is change the last line of the .tik
Well I guess you didn't do it exactly right try it again .
1. open a tree tik file in notepad and find what shaders the surfaces use
2. find the scripts/trees.shader in pak0.pk3 and open it in a new notepad window
3. find the shaders in trees.shader that where used for the surfaces
4. Open a new notepad window and copy the shaders that where used for the surfaces into this window then close the trees.shader window
5. Find the .tga names that where used in the shaders
6. open pak2.pk3 and extract the .tga files that where used for the surfaces that you found in the shader
7. open the .tga files in a program like photoshop that can open .tga files
8. edit the .tga to make it purple
9. save the .tga's giveing them a name like purple1.tga purple2.tga etc
10. put your .tga names into the shader and give the shader a new name like purple_tree1 purple_tree2 etc
11. save the shaders file as purple_trees.shader and put it in the scripts directory
12. put your shader names for the surfaces in the tik file and save the tik file after you have changed the quaked statement at the end so it shows up in radiant and renamed the tik to something else such as models/mytree.tik it must be in the models directory .
Thats all there is to it as long as the tik's surfaces use your shader names and as long as your shaders in your .shader file point to your .tga's it will work .
I will let you try again if you can't get it I will make one for you to learn from OK ? It is almost the same way you make custom textures to use in the game . The only difference is that the tik uses the shaders for it's surfaces instead of you putting the texture on a brush . Once you learn to make a shader you can reskin ai's or any model you want . There is a lot you can do with shaders . You can make a flag that flaps in the wind . You can make custom fences or custom water affects . You seen the cool map on the .map opening page , it uses custom textures that have shaders that tell the game if they are stone textures or grass etc . Good luck .
