Sorry! 'Can't find mesh' could mean the package is recolors of a CC item which doesn't include the meshes, or possibly it could be a clone of an item in a pack you don't own. Saving a blended package with items that use different sets of meshes could definitely mess up the package so I'd do it with caution and always save a new package and keep the original.

Is there a place to download older versions?

Which version do you want?

this is a screenshot of the tutorial I am trying to use but its an older version and its hard to follow with the new version

That's a VERY old version, won't work with packages made in at least the last couple of years, won't clone any game items added in packs and updates, and will make packages that may not work as expected in patched games. You're better off trying to follow the tutorial anyway.

I've found that this gives me an error when I try to auto-assign UV1 and then click "commit changes".

Please upload the mesh you're trying to convert or the package you're working on, the reference mesh you're using if any, and a screenshot showing the tab and settings you're using.

I think it finally worked, despite the error. Although it still does give me an error.

For this one I included a head mesh that's not a part of the whole thing, but is that what's causing the error? It was cloned from the tuxedo originally.

Head meshes tend to be a problem since they have three UV maps, not two. I suspect the tool is throwing an error because of the mix of two and three UV sets in your meshes. Probably the right way to do this would be to convert the head and whatever other parts you're having trouble with separately in the Mesh Tools / Auto Tools tab and importing those converted TS4 meshes to your package. That's only if the mesh isn't working in your game, of course.

hi everyone, does someone can help me? i cant use the auto-assing UV1 i don't know what happens but it throws me an unexpected error, any solution?

I can't tell you anything with no information. Please upload a screenshot of the tool showing what you're doing, the text or a screenshot of the error, and the mesh you're trying to auto assign.

When is the update for S4 CAS Tools coming out? The "Throwback Fit Kit", "Country Kitchen Kit" and "Bust The Dust Kit" have been released for a long time.

What exactly is the issue? Are the items not showing up or what? Packs and content coming out don't usually need an update.

Hello, I'm still new to the tool and I just wanted to enable a makeup blush for aliens and I succeeded in that but the color swatches aren't showing and I was wondering what did I do wrong. Thank you for your mod by the way!

Please explain what you mean - where are the swatches not showing? In CAS? For aliens? And please upload your package.

Oh my god, the auto assignment function saved my life!!!

I'm running into a problem now, however. On some of my packages, when I use the auto assign under "mesh fixing tools," I get a dialogue box that says, "unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.

Object reference not set to an instance of an object."

then these are the details:

See the end of this message for details on invoking

This only happens on some of my packages, and when it does, if I click continue and try again, it keeps popping up. I can't commit changes or save the package. It's be one thing if this were happening to only one package, but it's multiple.

Edit: It's happening with all of my shoes, but there are other ones too.

That error suggests it's a mesh with no vertex colors, but I can't be sure. Please upload a package this is happening with and say which auto assign button you're clicking.

Hello! I'm editing some custom content (for my personal usage). I'm having trouble distinguishing between swatch colors, so I'm adding new custom swatch thumbnails.

When there's multiple files of same cc but for different categories (such as face details, tattoos, makeup), is there a way to copy all the swatch thumbnails from one pack to another? If so, how? I haven't been able to figure it out.
I suppose a workaround could be just edit the categories from one file, but I'm slightly nervous of messing up. Editing just the thumbnails feels safe to do.

There's no way to do it automatically if all the swatches have different thumbnails. If you can use one thumbnail for all the swatches, you can open the package with the thumb you want to use and export the image in the Thumbnail Manager tab, then open the other packages, import the image as an overlay, and apply it to all swatches. You can also use the overlay feature to import just a logo or name or whatever with a transparent background and apply it over the existing thumbs.

Thank you! No, sadly the thumbnails aren't all the same, but there's repeating ones, so I suppose I can take the one that's most common and do what you instructed, and then manually edit the rest.
So does editing in Thumbnail Manager tab affects the swatch thumbnails? I thought I'd have to be in Recolor Manager tab for them?

Yes, use the thumbnail manager to modify all the thumbs. The recolor manager shows you the thumbnail but doesn't let you change it.

Ah, I'm sorry, I'm talking about the square swatch thumbnail, the one that's visible in CAS when choosing which recolor of CC to use, not the rectangular one that shows which recolor you've already picked.

Ah, I always forget the swatch thumbnail. Sorry, that one is assigned in the recolor manager and there are no shortcuts, sorry.

Thanks so much
