The shaders are in the effectbank folder under files.
Each one does a different thing.
In the editor when you right click on an entity. Down below the texture spot is where you can change shader FX.
Some shaders only work for Boned skinned entities (character or anything rigged with bones)
Some only work for Segment Items
Some only work for Static entitys
Some only work for dynamic entitys
Some are full screen process' like Bloom and Depth of Feild and other custom ones made by Forum members.
Switch them and test the level.
Also you will need to shut down FPSC and look at the setup.ini files in the top section and you will see some more options for shaders in that. setupdescription.txt will explain what is what in that file.
Usually if an entity or object is not showing up, then either the shader is being use as not intended. Or there are not enough textures for the entity to complete what the shader needs to diplay proper. Some times you may need to make adjustments to the textures them selves, if you are using custom stuff.
If you intend to modify a shader. Open it in notepad and look for
tweakable listings. They will be in the upper part of the shader file
Hope this helps
