In 4.6 can no longer change material of sprite in character blueprint

I built a few levels in 4.4 and my character consisted of a blueprint containing a sprite. In 4.4 I could change material of sprite, changing it from default to defaultlit. Now I don’t have option in component tab of blueprint. How do I change material of sprite in blueprint now?
