How to save a render image as JPEG with white background instead of default black background at alpha transparent areas? My render image has a transparent background and when i save it as PNG RGBA every thing is OK. But when i want to save as JPEG format which doesn't support alpha transparency, save it as black backgroud at transparent areas.
How to save a render image as JPEG with white background instead of default black background at transparent areas?
Just like when i save the render image as PNG RGBA format and open it in GIMP and save as JPEG format which change transparent background to white.
Is anyway in blender without using Nodes?
No, but it's quite simple to do with nodes..

In the compositor (press &#9096; Ctrl&#8592; Left arrow), enable Use Nodes in the header and add an alpha over node (&#8679; ShiftA> Color):



The color in the top slot is the color which will be used instead of transparency.

Now transparency will be automatically filled in with white (or whatever is in the top socket) when the scene is rendered.
