I imported one image picture on new layer for make TGA files with original picture`s transparency
after that I made some moving partikle on it
And export TGA files of caurse checked 'save alpha channel '
but the result was net good enough that i couldnt see well original picture
it had transparency but picture was unclear
so I did other ways which I could in checking other options
but also other result were not good
How can I get both good result with original picture with that`s transparency
and new partikle to TGA files?
I will really happy if I can get answer
thank you have a nice day
When you export images of particles, the only alpha channel that's preseverd are those of the particles, not the BG image.
You are best rendering out the animation with the BG turned off, and with preserve alpha channels set to on - and then compositing the particles and your BG in a compositing program like After Effects (or whatever you use).
Otherwise, keep the BG turned on, and don't export with an alpha channel, if you want to see your BG image.
