Styling#

Custom shaders#

Custom shaders are available through USS filters as of 6.3.

Alternatively you can hack in your own custom shader, but note that this will break batching. Or, use render textures (e.g. CustomRenderTexture), though note more than 6 unique (un-atlased) textures in a hierarchy breaks batching.

No glow/drop shadow support.#

USS filters are available as of 6.3.

Alternatively, use custom textures and nested elements, or hack in your own with an extra element or binding and mesh generation.

Text#

• Rich text tags (e.g. <color> and <link>) can't be targeted by USS, and therefore can't respond to dynamic styling.
• Max visible characters support can be manually implemented as of 6000.2¹.
• No support for dynamic text gradients.
  • Hack in your own support to populate the static and internal Color Gradient asset lookup.
  • Or use custom text animation¹.
• No percentage font sized text.
  • Auto-size support is present in the Advanced Text Generator as of 6000.2.0b4.
  • Alternatively, calculate and set font size in code.

Vector images#

• No anti-aliasing of VectorImage.
