When I using draw3d bilboards are drawing in order of functions call. Is there any easy way to draw images in fixed order? Or I have to sort them manually?

Manually drawing blended geometry, such as particles and VI calls for example will draw immediately, in the order you call them. If you require a specific order and cannot call in the order you need, then it would be better to queue the calls up, sort them (by whatever you need, such as distance to camera for example) and then run through the queue calling draw in sorted order.

Thank you, I was thinking that the way, but I wanted to be sure.
