A new project on 3.13.1 is ok, but a new project on 3.14 doesn't set opacity. The code I used in HelloWorldScene.cpp on both projects is this :

SpriteFrameCache::getInstance()->addSpriteFramesWithFile("buttons.plist"); auto button = ui::Button::create(); button->loadTextureNormal("buttons/play-big", ui::Widget::TextureResType::PLIST); button->setPosition(Vec2(visibleSize.width/2 + origin.x, visibleSize.height/2 + origin.y)); button->setOpacity(100); addChild(button); 

Steps to Reproduce:

1. Create a new project
2. Add a spritesheet
3. Create button and set opacity
