Revit Walkthrough transparent background

[kelvin_ng_1201]

I rendered the walkthrough of my building with transparent background, and thinking to give it a nice sky background in aftereffect, however, the mosaic background is actually showing mosaic in aftereffect. How should I make that mosaic background to be transparent in aftereffect.

Change the Background under Graphic Display Options.

I did. However the walkthrough video i get still have the mosaic background...

Isn't that what you want? A transparent background?

Maybe you mean WHITE BACKGROUND? 

Otherwise,  the Checker background can be replaced with an image or with another animated scene in a video editing software...DO you have any video editing software? The walk-through will be a video file in the end no?

Alternatively...do your walkthrough in a different software. Enscape has some Not Bad sky scenes

but look at my attached image in after effect.

Once i bring it into after effect, it still show mosaic background but not transparent background.

usually mosaic is just mean transparent. but once i bring it into after effect, it actually still showing mosaic...

I don't use After Effect.  Does the Transparent Background go to a Layer that can be turned off?

Checker board indicates Alpha channel, meaning it is transparent.  Just replace background in After Effects and save the final video.

Your image from After Effect was not attached.

In after effect, if you toggle Transparency Grid preview what do you see? Can you take an image of that?

[kelvin_ng_1201]

No I meant transparent background. but might be white background would be easier for me to photoshop or aftereffect the background out...

[kelvin_ng_1201]

it was attached in my first message.

I will try that, thanks!

[kelvin_ng_1201]

no.. the background was not in a separate layer that i can easily toggle off. but i know the way in the after effect or photoshop to take them out. it is just a extra step i would like to avoid if i can...
