Outdated (for reference):

pbox - The Blender 2.6 GEOM tool by cmomoney says it is for TS3. Will it work for TS4?

I'm copying this info over to the wiki - http://simswiki.info/wiki.php?title...ools_for_Sims_4

As I understood it, some? few? many? creators are converting TS4 -> TS3 at the moment, do all their meshing there (since they can use all the tools that are available for TS3), and then convert back. There’s a GEOM converter among Cmar’s Mesh Tools, too. (That particular editor was also recommended by someone who did meshy stuff for TS4 .. I don’t remember who/what/where though)

Thanks for the update.

@porkypine, there’s one more resource I haven’t linked yet: http://www.modthesims.info/showthread.php?t=533073 (will do so now)

Hi,

I downloaded the DDS plugin for PS but the program won't read the file. I rebooted my PC a few times and still it doesn't work. Any thoughts about what I should do ?

Thanks in advance

sims 4 studio http://www.den.simlogical.com/denfo...hp?topic=3226.0

Thanks, I was just about to add that =)

http://sims-4-files.wikia.com/wiki/Sims_4_Files_Wiki
The site's focus is on CAS content at the moment, trying to categorise everything, listing flags, ect.

Updated the links to sims4studio since their move from simlogical and github.

Thanks lee! Also added link to that wiki.

This Python decompiler/compiler ought to be in the list:

FYI, thread has been deleted.

S4PE 7zip is being reported by malwarebytes as a trojan, i cant be bothered signing up to yet another site so can someone pass it on to them if you can be arsed. :D

s4pe.0.2.c.7z is not reported by Malwarebytes as a trojan.

Please! Make s4pe installable!

What do you mean, "installable"? There is no installation needed .. simply unzip the folder, there you go.

S3PE has a exe version that you execute in your system and the exe installs S3PE on the system.

Can you do the same with s4pe?

Please note, my wrappers are in the process of being subsumed into the main s4pe repository and probably by the time of next release will no longer be needed as a seperate download.

But right now they are still necessary, are they not? I just opened a COBJ in the 3a release version without your wrappers and that doesn't look very promising =P ..

Hi, I came here to say that my Hasher tool had moved and changed name, but I see here that you already beat me to it.

But I noticed that the link has an extra "h" in the beginning. So I though I might take this opportunity to ask you to change to link to this page:
http://fogity.boards.net/thread/4/modding-toolbox

This is my release post about the tool which links to a feedback thread etc and will link to the latest version if I update.

Fixed; thanks for the heads-up! =)

@plasticbox A program to see the dds file UI.package http://www.nvidia.com/object/window...ure_viewer.html

This seems to be able to edit http://developer.amd.com/tools-and-...compressonator/

Thank you, I added them both! =)
