I am a bit confused by that post. Version 4.00 ?
I am very sure it works with v4.36 fine. The updated version of DecalStay
that I tweaked to support the new decals in the MoreBlood mutator was
complied with 4.36....
DecalStay will not load automatically due to the way it was implemented.
You do need to go the Mods/DecalStay config menu and click Update every time you start UT
for it to start.
Of course I would recommend you download MoreBlood RC7.5 and use the version of
DecalStay I included with it, as it will use the new blood decals in place of the default ones.
(in any game, online or off)
