Hi guys!
I am trying to make a torch with sprites particles.
I don’t understand why in viewport everything looks fine (shading -> hardware texturing is on)
But in preview render it’s looks like my sprites without alpha or with background colour.
I checked twice, all of my images have an alpha-channel. Images are saved as TIFF without layers.
Here the image:

I tried to google it first, of course. So… please help!
