Where did you get the render? If you got it from planetrenders you might need to dive just a bit deeper when picking out the render. Say you found a render under comics that you liked. First click on the thumbnail image. That will open a bigger picture of the render (it will have a black background). Instead of right clicking and saving at that point click on the picture of the render again. that should open a whole new window. the render will have a white background. Right click and save that image. It will be the png file which will have a transparent background.Originally Posted by Wii_Smurf
Hope that solves your issue.
