@BlackMagic55 This mod already exists! https://www.gta5-mods.com/maps/willis-tower-of-chicago-menyoo

@BlackMagic55 Thanks!

@Stig86 You are right! We really have this bug when switching characters and I haven't found out the reason.

@FJ28517 This map has a lot of props and it would be very difficult to move everything, I think you can only move the main structure with the base and the two buildings, you can try with this tool: https://www.gta5-mods.com/tools/ymap-ybn-mover

@design mike Yes!!! I like it.

Great mod!!!
I was also thinking of doing something like this, but I was going to create a YDR with collision and texture built into the 3DS Max + GIMS EVO, I believe you modified it very well too. Your idea opens up a wide field for us to be able to externally modify the appearance of buildings without changing the entrances/exits and other relevant aspects of missions. Have you ever thought about doing something similar for the Mile High Club?

@Soaring_Wings
Yes, I've been using AutoCAD since 2004, I find it easier to create models. But you can use other software like Google Sketchup or natively on 3DS Max. On Youtube we have excellent tutorials like this:

@NaijaMango But my thought is precisely that, to spread new skyscrapers across the map of Los Santos, in the empty areas. I was very disappointed when I saw GTA V for the first time, even though it is based on a real city that doesn't have many skyscrapers, it is ridiculous in the variety of vertical constructions when compared to GTA IV. I sincerely hope for a new GTA with more buildings and possibly all accessible interiors. Imagine a GTA in Dubai? It would be amazing.

@Soaring_Wings
Would you believe that this building I made by accident? I just opened 3DS Max and drew a rectangle, extruded it and put random coordinates on the ymap and it appeared in that place. Then I improved the structure, put textures and I think it was good, it was my first mod in GTA V.

@Soaring_Wings
You or whoever downloads the file can move it anywhere in Los Santos, just edit the .ymap, I prefer the original place. The base version was too far away in x, y = -6000 , 6000 coordinates.
