Render with a white background

posted to: Bouncing Ball

I did everything correctly and the viewport rendered normally, with a very nice movement of the ball. But when generating the mp4 file the video came out with a white background, which covered up the path points. I've tried changing many of the rendering variables with the same result. I don't know what's wrong.

    Perhaps you were working on material preview with a different background set. Try changing the world background color. In any case attach some screenshots and your settings to see more clearly what is going on.

    Hi Alexandre,
    Make sure you are not doing a 'real' render.  We just want to render the viewport in this course.

    You can set all the render settings in the render output (sounds like you have done that)

    But then at the top of the 3d window > View > Render Viewport Animation

    That will render out what you see in the viewport - except for a view things.....

    Like the keyframe numbers and armatures (and some other stuff that's not related this this)

    Hope that helps.

    Also, make sure that in your Render Settings, under Film, you haven't checked Transparent.

    MP4 doesn't support transparency and will make the transparent parts (here: background) into a color (here: white...maybe it's always white, I don't know....)

    It seems Omar is on the path to a solution, but it hasn't worked yet. Though I'm on solid mode, there was indeed a white background. I changed it to somewhat gray, but the background continues to block the display of the path keypoints and the animation color is strange.

    I copied all settings from the square-in-square exercise, that was ok. From the beginning, I had already been doing Viewport Render Animation and left the Transpartent Settings unchecked. But I keep getting this result...

    "and left the Render Settings at Transparent"

    That might be your mistake, as I mentioned above.

    Sorry Martin. I got confused in the answer. Transparent Setting is off

    Oh, that is weird...

    I can't see anything wrong with your settings...all looks normal to me...

    I can't reproduce the result as you have it...

    Here are some things you can try:

    Disable all third party Addons.

    Check your (especially GPU) drivers.

    Open a New Blender and Append the Scene, then switch to the Appended Scene (comes in as Scene.001, by default).

    Re-download Blender.

    You can also try loading the Image Sequence into the VSE and Render that as MP4...

    You are rendering straight to video? Yeah I guess the best way is to render a PNG sequence and then generate a video from that sequence.

    I disabled my addons, checked my GPU driver that reported working normally and appended the scene to a blank file. Same result unfortunately.
    I tried rendering straight to video (no changes) and loading frames to VSE and rendering from the sequence (also no changes)
    Since it seems there isn't a silly noob mistake (my main concern), it's probably some weird bug on my file that won't repeat itself.
    If it's ok with you guys, I'd drop it and move on.
    Thank you guys
