Hello again, 
I´ve got a small Hollywood / Los Angeles sign transformation pack for the Los Santos Theatre (San Andreas Avenue, Los Santos) 
+ further small changes for that area for you.

Installation: 
1. Open OpenIV and enable edit mode.
2. Go to C:\Games\Grand Theft Auto V\mods\x64i.rpf\levels\gta5\_citye\downtown_01\
and replace the dt1_16.rpf folder.
(optional) replace the dt1_16_superlod.dds file in the dt1_lod_06_07_08_14_15_16_17_children.ytd folder which is located in C:\Games\Grand Theft Auto V\mods\x64i.rpf\levels\gta5\_citye\downtown_01\downtown.rpf\

3. Enjoy it.

It´s highly recommended to backup your files before doing any changes.

All the best, Michael : o )
