Many materials share the same texture between Diffuse and Emission. Set the emission power with this slider.
Some transparency can be set with the next slider, open its texture manager to control transparency with Black and white image pixel values.
Be aware that if you’re in Eevee or LookDev shading mode you have to click the button to set the material as Is BLEND, Is HASHED or Is CLIP in order to use transparency.
Is BLEND blends every pixel between material and transparency, Is HASHED perfoms the blend in a noisy fashion (faster), Is CLIP sets as transparent only pixels under a threshold value (useful for texture controlled transparency).
