Hi, i get this all the time. I guess as described i have to play with drivers? I noticed it happens only when i have denoiser enabled.
edit: it happens when i copy paste objects while in live viewer mode. IT happens also if i close and restart lv.
edit2: oh it happens also without denoiser

Hi Aoktar. This feature still outputs images without alpha channel (in R4 version)
- Added the functionality of saving the any render pass from Live Viewer. You can save a render pass with RMB over pass buttons in Live Viewer

I checked this after your last post. I rendered out a scene in the new version and it out put the alpha just fine for me. PNG 16-bit. Looking at it in Photoshop and it layered over another image fine. Just did it again to test.
But maybe you're using different file types than me.
This functionality is very usefull. Thank you, Aoktar.BCres wrote:tomsvfx wrote:Hi Aoktar. This feature still outputs images without alpha channel (in R4 version)

However the alpha channel is not correctly saved, I can't make it work here... .EXR or .PNG linear or tonned, it turns to save a black background.

Which passes do you try? It's absolutely working on me. Could you enlight me better by adding a saved image here?Kalua wrote: This functionality is very usefull. Thank you, Aoktar.

Kalua,
From the LV are you saving via the menu? Then yes, it seems that only saves the Main pass.
What you do is right click on the Demain tab at the bottom and it will give you the option to save. This will save the appropriate type with alpha. See image:

Thats what I've been doing... it works. However the alpha won't be saved, I get a black background.
Maybe I'm missing some step...
EDIT: even if I export each image to the picture viewer I get the same result, see attach.
What am I doing wrong?

Sorry but what's tricky? Just click on button, call the save as tonemapped PNG. And open in after effects or pshop to see results.Kalua wrote: Im trying the Beauty Denoised (wich is the pass I found tricky to save out of the live viewer... unless I miss the point.

Kalua,
I'm sorry I can't figure out why yours isn't working. I've attached four pics to show you the only settings I have turned on that might affect it. (My max samples are set low so I could tell I was saving the Denoise w alpha and not the Main, which I was.)
If it's not one of these, I'm out of ideas.
