Thanks for the input folks. I can’t do all the tests you suggest as I recently deleted the latest offending scene after creating a new one from it Linking Object Data - my usual work around this issue. I have confidence this will occur again and will then do some of what you suggest. That said, some of your suggestions I already did.
There are no key frames. This was occurring when the only thing happening was a fire effect. But I checked and in the dope sheet selected all and deleted only to be told what I could see anyway, that there were no keyframes to delete.
As for what keyframe I’m at when it occurs - doesn’t matter. It will render from the same position and keep the keyframe I chose. Funnily enough the flames adjust to the keyframe chosen. (at least in one test)
It’s like something OTHER than the camera is set to be the camera but it coincides exactly with a recent camera position. I go though the outliner and there are no additional cameras listed. I did a render after deleting all the cameras once and did get the same render. What stumps me is the coincidental exact placement of the render from a previous camera position.
Re OpenGL Render Buttons in 3D view… I usually just hit F12 though I may have hit those to see what they did at some point.
Sundial - I do most of my stuff in camera view, occasionally switching to Ortho views. So you’re saying I should use the render buttons at the bottom of the 3D screen instead of F12? I’m a bit confused about what those are for. I hit them and the camera icon gave me a Black screen with outlines of the lights. When I hit the movie render icon it started to generate the fire effect but the rest of the scene was black and again, all I could see were the light outlines (dotted lines) and the fire.
No idea what the “Stamp” feature is or where I would activate it.
Did I mention I’ve been learning this for less than 2 weeks? ;-)) SOOOOO much to learn!!! (So little time…) But I love it! It’s like live action filmmaking but with no limitations - except for my ignorance in the software and tricks of your trade! Ha!
Thanks for your patience guys (gals), its appreciated.
