The rituals of a Buddhist funerals vary with the tradition (Theravada, Mahayana, Tibetan) and sect. The social aspects (dress, interaction, meal) of the funeral depend on the congregation and the country or cultural group they are in (an American Buddhist funeral might be more like other American funerals than Chinese funerals) If you are attending such an event call the funeral home if one is being used or a relative who is Buddhist to get the details of what goes on. If you are only going as a social thing (coworker etc.) go but plan on getting no freebies.

Buddhist art in the first century relied on symbols and iconography to convey spiritual teachings and principles, reflecting the symbolism and imagery found in Buddhist scriptures and teachings. It also drew inspiration from local artistic traditions, resulting in unique regional styles across different Buddhist cultures. Additionally, the patronage of rulers, nobles, and wealthy individuals played a crucial role in supporting the creation and propagation of Buddhist art during this period.
Funeral services often include prayers, readings, eulogies, music, rituals, and symbols that honour the life of the deceased and provide comfort to grieving loved ones.
Buddhism has adapted to different cultures in different places; it did not start out with any particular rituals around death -- since it was an anti-ritual sort of religion. However, different cultures have different customs. If attending a funeral of an American Buddhist you should wear what Americans wear to funerals. Aside from that, you would be wise to ask a member of the family, the Buddhist group, or a close friend of the deceased for advice.
