Go ahead and call me stupid for not knowing this but I have no idea how to do OpenGL renders in Blender, and I kind of need to. Can anyone who is smarter than I inform me on this?
Some other info: You can render what’s in the 3D View window, in which case the framing of your image is a bit hard to predict exactly, or you can render the view of the Active Camera, in which case framing is WYSIWYG. Either can be useful depending on your needs.
The Animation button (scene clapper icon) will write to whatever filename & destination you’ve set in your Output field and WILL overwrite files there without a prompt. Be cautious.
Thanks so much for you responses, all I needed.
