I want to make flare effect for cars. Right now flare is plane object with texture and billboarding. Now I need that flare become smaller when it come closer to camera and larger if go from camera. I have only one idea - to set scale flares every frame, depending on its position.
Maybe JPCT have some feature for invert Zaxis zoom or to make it more easy for phone?
Sorry if I miss something in documentation.
Your idea is fine. There's no magic included that does this, you have to do this yourself.
Thank you, it work already. And not so slow as I thought.
