lltexturecache-browser-qt

lltexturecache-browser-qt is a cross-platform tool to browse and export textures from the second life texture cache.

this application is useful if you want to mod existing assets on second life, like character clothing and the author does not provide a texture to download.

lltexturecache-browser-qt only reads what is stored in your cache files. it is not a copybot and should not be used to steal assets.

the app's icon, slcachegirl, is designed by @sferics32.bsky.social.

features

• browse and filter through a large amount of textures
• find a texture by a screenshot
• save to disk in commonly-used image formats
• drag and drop support
• it's fast
• it's not an electron app

i want it

windows, linux and mac builds are attached to each release. on mac, open the .dmg and drag the app into Applications.

on mac, you may install with homebrew:

brew install --cask furudean/tap/lltexturecache-browser-qt

platform requirements

platform	runs on
mac	macos 15 sequoia or later, apple silicon
windows	windows 10 or later, x86-64
linux	glibc 2.35 or later (ubuntu 22.04+), x86-64

intel macs are not built for.

to run from source or build your own, see develop and build.

developing

use uv to run the app in a development context

uv run lltexturecache-browser-qt

build

a script makes the app for the host platform. mac gets a .app windows .exe and linux a binary/AppImage. cross-compiling is not supported.

./scripts/build.sh

needs	on	for
uv	all	running the build
patchelf	linux	nuitka to fix up the rpaths of the bundled qt libraries
libxcb-cursor0	linux	nuitka to have a copy to bundle into the binary

none of it is needed to run the result

release

publishing a github release builds for all platforms and attaches the binaries to it. write what changed under the ## unreleased heading in CHANGELOG.md first, then run:

./scripts/release.sh major|minor|patch

the script will

1. bump the version
2. retitle ## unreleased in CHANGELOG.md to the version and date being released
3. commit that along with the bump, and tag it
4. push
5. create the release with notes from the changelog

the release triggers a github workflow. which does the rest

sign / notarize (mac only)

signing needs a developer ID Application certificate in a keychain the signing machine can read, plus the environment below. then

./scripts/build.sh
./scripts/macos-sign.sh
./scripts/package.sh

macos-sign.sh re-signs the bundle with the hardened runtime, notarizes and staples it; package.sh then makes the .dmg with another notarization pass.

notarization is skipped when the credentials are unset, so it degrades to a plain signing step. in CI macos-keychain.sh runs first to make a throwaway keychain out of MACOS_CERTIFICATE.

variable	is a	needed
MACOS_SIGN_IDENTITY	e.g. Developer ID Application: Your Name (TEAMID)	signing
APPLE_ID	Apple ID the app-specific password belongs to	notarization
APPLE_APP_PASSWORD	app-specific password	notarization
APPLE_TEAM_ID	last part of MACOS_SIGN_IDENTITY	notarization
MACOS_CERTIFICATE	developer id application certificate as .p12, base64 encoded	keychain in CI
MACOS_CERTIFICATE_PASSWORD	password the .p12 was exported with	keychain in CI
