## [4.6.3](https://github.com/mob-sakai/ParticleEffectForUGUI/compare/v4.6.2...v4.6.3) (2024-04-04)

### Bug Fixes

* if only Trail Material is used, it will not be displayed ([2eff411](2eff411bd9)), closes [#294](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/294)
* if the UIParticle parents do not have Canvas, an exception is thrown in OnEnable ([e82c833](e82c833d04)), closes [#300](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/300)
* particle size too small due to auto scaling ([2ec3748](2ec3748336)), closes [#295](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/295)
