No alpha channel. Why it happens?

Hi! Could you help me please? I am trying to render simulation using Premultiplied/Straight Alpha option in Render Export settings (screenshot is attached).

But after rendering checking Alpha channel in After Effects I don’t have it (screenshot is attached).

Could you tell me please why it happens?

Hi Tom, can you check your connections in the Render Node? It should look something like this

Thank you so much! I don’t know why I thought it is enough to set flag to “premultiplied alpha” to get render with alpha channel… Yeah, I am strange…

No worries, there are a lot of menu items and it’s tough getting used to the intricacies of new software. Let me know if you need any assistance in the future!
