Edited the OP to reflect graphical improvements and new features.

v.20 is now available, which includes:

• Fixed cloth rendering problems
• Fixed some YFTs (eg. traffic lights)
• Fixed water foam rendering issue
• Entity transform widget
• Project window enhancement
• Full source code included in download

Enjoy

V.18 is now available!

@PNWParksFan I hope the new tool proves useful for you:

It is accessed via the "Info window..." button on the Selection tab. Enable the Mouse select checkbox, and select an object in the world to see its details in the window. When CodeWalker is in Model view mode, the details of the current model are displayed.

Screenshot from the new version:

Added v.15 which now can render collision meshes (among other improvements).

Hi everyone,
I've been working on a 3D map for PC version of GTAV. It's at:
https://www.gta5-mods.com/tools/codewalker-gtav-interactive-3d-map

It now allows entities to be placed and moved, also new and modified ymap files can be be saved. This feature is still in experimental stages, but I would love to hear any feedback on it!

Enjoy!
