I have modified the original scripts as released by DLA and available on both vaults.
These modifications include adjustments to allow all three of the mentioned tools to work with 3dsmax2014/2015 but will also likely work with earlier and/or later versions of max.
Note that Veltools and Nwmax also orginally claimed to work with Gmax, I have made NO edits to those sections of the code so likely these new updates will now also work with Gmax, but I have no way to test them.
NWN-Set, or Tileset Creator by Velmar, this release is a much updated version that never made full release to the public by Velmar and was in storage on the DLA site just prior to DLA closing up shop. It includes many features that were never seen by the public at large, most particularly the mini-map creation bits, AND group handling for the given .set file that you have loaded within it. Velmar had given me specific permission to release this version, I did not realize that this version had not actually been placed onto the vault. Please note that TSC is very SLOW to load and to export the .set file, but it gives enormous power to anyone working with a tileset's .SET file. It has tools to allow you to 'see' just about everything related to a tileset and to edit each bit as needed. It is truly a godsend for folks working with tilesets as it allows adding, removing, duplicating tiles and/or groups to the .set file, up to and including the 'hidden' details that can sometimes confuse folks. It was never intended to work with Gmax and to my knowledge has no code to work inside of Gmax due to needing to implement the listener.exe that comes with NWmax.
Veltools 1.25
(Please also note that there are scripts that are included as 'quick scripts' within veltools, some of those, not all, but some will likely fail with later versions of windows but are not used all that often by any tileset modder anyway, things like creating haks for all folders specified... the script runs, but windows8 onwards block the actual action)
NWMax 0.8C00
NWN-Set 2.09
The edits I have made strictly corrected issues that prevented these scripts from loading in the later versions of 3dsmax due to the much stricter scripting language abilities built into the later versions of 3ds. This includes how 3dsmax handles variables, loading files, function returns etc. I have also removed a huge number of old/usless/never intended to be added files that have accumulated within these various tools over the years, extra temp folders, copies of files generated as reports from sanity checks (over 1 thousand extra files deleted here, which are only reports of various files that failed sanity checks by the author of NWMax) and I have included the most up-to-date versions of erf.exe and nwnmdlcmp.exe that are called from within these scripts.
Version numbers were changed to reflect the fact that I have had to edit them. I make no promises that anything works specifically, but they do load and run on my machine. If you have issues with any of these, let me know and I will see if I can fix those issues, again, no promises other than that these script sets WILL take up space on your HD.
Also note that NONE of these are self-installers, as such you will manually have to extract these, including the folder structure, and copy the resulting folders directly into wherever the main 3dsmax.exe file resides, overwriting/adding to whatever files are there.
Special warning on NWMax0.8C00, it can not be loaded in max memory at the same time or same session of 3dsmax/gmax as MDA's nwmaxplus version as nwmaxplus was a direct copy that was modified by MDA and uses many of the same variable names etc. As such, you can run either or in one session of max, but must completely exit if you wish to run the other version then reload max, and run the script that you choose to run.
Also, each of these script sets includes a file that will go into the 'startup' folder of 3dsmax/gmax and will automatically load them, if you do NOT wish them to auto-run when you start max, simply delete that file (there is a copy also located with each set of folders for each program so you can always recover the autostart file).
