==================================================
Some effects such as crack are not visible.
-------------------------------------------

Launch Thievery.

Bring up the system console.

Type in "preferences" and find rendering submenu for your renderer (ogl,d3d9/10/11 etc).

Make sure "volumetriclighting" and "highdetailmodels" are set to true.

Make sure that "FastTransparency" is set to FALSE.
==================================================
My game crashes.
----------------

You should try a different video renderer, use the Change Video Options shortcut in the shortcuts folder if required. Usually a crash will force this mode to load next time you launch Thievery.
==================================================
I wish to modify the files and make patches.
--------------------------------------------

Check the Mapping folder. I advise you not to check the source until you are fully confident you have seen all the surprises there are to be seen in the mod.
==================================================
Maps not included wont load due to xmaps skipping.
--------------------------------------------------

Copy and paste the xmaps.int file from the Help>XMaps folder to your UT>System folder. Add it to the mutator list when you next start a multiplayer game. You can now edit xmaps maps list to allow the custom map(s).

The reason for this not working is to keep a standard install in a vanilla map state which will be fine for most people.
