Need to test: localassetbrowser preview related floaters hgfloatertexteditor maps media textures! Currently very hacky web browser alpha masks on avatars bumpmaps Are all sky components appearing? LLViewerDynamicTexture (texture baking, browser, animated textures, anim previews, etc) Snapshot related features Customize avatar vfs floater UI textures in general Texture priority issues
