mod dekaron

In one of the dekaron servers I play I do not like the scenery of the map. Is there a way I can mod it to change it for myself? Also, maybe costumes as well.

note: I never done any moding before so answer as you talking to someone new to it. Please point me in the right direction (:

Get photoshop cs 6, dds plugin don't work with newer photoshop CC versions, search on google nvidia dds plugin, and install.

Now go into ur Dekaron> Data>Tetxure> map tile, this folder is for terrain of the map, just drag any dds file from that folder into photoshop, and load using defaults.
For objects on the map u find the in object folder, for characters> character folder, also costume folder, just drag dds files and see which are which.
When u save them back in the game, check on the photoshop layers side, the channel tab, if that channel has an alpha layer there, make sure u save as DXT5 - Interpolated Alpha, if there is no alpha layer, just save as DXT1 - NO alpha , also in the dds window exporter check the box " No mip maps ". Have fun exploring dds files
