Hi,
I want to RenderTexture half the node ,i don’t want to use mask .

this is my code to render first half of the node i want to get the second half .

auto renderTexture = RenderTexture::create( shape->getContentSize().width/2, shape->getContentSize().height);
        renderTexture->begin();
        shape->_drawNode->visit();
        renderTexture->end();
        renderTexture->getSprite()->getTexture()->setAntiAliasTexParameters();
