how do you make renders, wat is ur aim so you can walk me through it. And once you make a render, if anybody knows how, how do you insert it into a gimp picture.
Get any image, lets say a jpg img for example, there's a tutorial on rendering either in the premium tutorials or normal tutorials I think, find one of those, follow that, and if your picture is saving with a white backround that means that you haven't changed the thing to layer, e.g, when you open a jpg, it isn't as layer it's as a "Backround" so you gotta double click that (Photoshop) and then it changes to Layer 0, then when you save it as a .png it'll have no backround, but as for Inserting it into a GIMP picture, I don't know what you're talking about there, sorry.
