Spritesheet based particle


I am having 2 big issues with mine particle that uses spritesheet. I have created a simple material that uses flipbook node to iterate through spritesheet (image attacked). Then I created realy basic particle system and overriden the material using the one created by me.

Now in particle system when I set looping to 1 and duration to 1 is’s not visible (setting duration to 1.1 make it visible). The first frame of spritesheet is displayed again just before finishing. And while spawning emmiter it also has delay before starting (but those 2 problems are probably connected).

Amd I doing something completly wrong?
