Unreal Render Sequencer with Alpha Channel

[@ale_straccia]

Great tutorial, helped me a lot! If you render using Window/Cinematics/Movie Render Queue, UE4 exports the alpha channel in the right way, so no need to invert the alpha channel inside AFX

[@ALEINLOSANGELES1]

for an alpha video texture in game do this step 01 you need to have an alpha png sequence and the normal(no aplha) png sequence in the folder Content>Movies in Unreal Two folders, each one including the repective png sequence * File extension is impoirtant step 02 in the same Movies folder right click and create two Media>ImgMediaSource name them "Albedo" and "Alpha" Step 03 double click on the ImgMediaSources and locate the sequence path (you can click on the very first image in the folder) Step 4 Crete a level sequence or go in the one you have already In the sequencer click on "+track" to right and create a media track In the media track you just created click the plus icon and add the sequence You need to do this for both "Albedo and Alpha" So you will end up to have two different media sequences in your sequencers Step 5 Back in your "Movies" folder create two Media>MediaTexture name them "AlbedoMT" and "AlphaMT" Step 6 Back in your sequencer right click on the timeline media track respectively for "Albedo" and "Alpha" Properties and reference the media texture with the ones you created Albedo > AlbedoMT Alpha > AlphaMT Step 7 Back into the Movies folder drag the first "Albedo" media texture on your plane It will create automatically a material Step 8 Open up the material and set it to "Translucent" you need to have as base color texture the media texture named "Albedo" and as opacity the media texture named "Alpha" You can drag it into the material canvas or you can just create a "Texture Sample" and reference it Step 9 Do not forget to check the box in the LevelSequence inspector (details panel) that says "AutoPlay" in the playback section You can finally see that your sequencer is matching the video playback docs.unrealengine.com/en-US/Engine/Sequencer/HowTo/UsingMediaTracks/index.html

Thanks so much for this. I followed the instructions but I'm just getting a black background with no alpha on UE4.24.3.

[@sevenfreem928]

what about the shadow?? can we get the shadow in a plane with alpa chanhel?

[@rudecoffee]

Just a warning, when I turned this on and restarted; it takes a long time for the project to start up.

[@anton_zalko]

Yeah, I think UE has to recompile all the shaders in the projects.

[@TheWillvoss]

thank you so much for this... finally got my project/raytracing up and running... was it like this every time?

[@anton_zalko]

you mean the recompilig? Yes, it has to be done for every project.

[@TheHamt]

Thaaanks a Lot!

I did everything that was in the video and it works, but the second time I did it, it didn't work. For the first one I was rendering a camera looking up to the night sky and some trees in the middle, the second one: the camera was looking at the horizon with some trees and the sky but this time it did not work. Is it because the second time I am doing it in a mac or something else?

[@anton_zalko]

Sorry, can't help you really, maybe it is because of a mac, try maybe windows to find the source of the problem

[@DjMolt]

try with the post processing volume

[@GodOfDes]

@@DjMolt where to check in post processing volume ? i always render with a black background without alpha, not sure why

[@DjMolt]

@@GodOfDes Mmmmm I think was on the camera options check it there :D

how can fix slight color shift in the render output man! i done follow ur tutorial!

[@dmitrysmirnov495]

Thank you, Anton!

[@shamsfx8837]

Hi tutorial is great but i cant import exr sequence in Ae... Compatibility issue

[@yastremski]

FYI - if your camera or PPvolume has a screen-percentage that isn't 100/default (like mine was), you WILL NOT GET AN ALPHA CHANNEL! Set it to default :) Took me hours to realize this.

[@evening8990]

thankyou, this is a great find!
