I have to render the animation of a lipstick in png, so as to transfer it to After Effect and add a completely white background, when I open the photo it is actually transparent, but importing it to AF the background still appears. I am rendering in Cycles, could you tell me a solution?
(I already checked transparent tab and RGBA color management)
Thanks for your attention.
Yes, the background is rendered unless you choose Render-Film-transparent.
If you did this check the import options in AE, i haven’t used AE for 12 years so i cannot tell. Maybe i used 16bit export back in the day though.
Hi Kyrgr thanks for your answer, unfortunately, It doesn’t belongs to AE, there is some issue from blender
What are you opening it in to see the transprency?
i see it from my pc’ desktop
If Blender has exported it with a transparent background, then the issue is probably down to some sort of import setting in AE.
Are you able to attach a file that shows the issue?
Welcome 
…
You mean the rendered image ? And you imported it into AE without any other background set in AE ?
When a pixel is transparent then neverthless it also has some color. Regarding to the settings of the PNG (premultiplied transparency and… 
the other one) this might be show differently in any app…
So it may show white or some dark/lightgrey pattern to visualize transparency. I’m not used to AE… but you may simple mix it with your wanted background ?
By the way:
Why not…
…in blender ?
I don’t know if uploading it to the site here has changed it, but the file formet is jpg, not png. Jpegs don’t have transparency in them.
You uploaded not the rendered ping but what is shown in blender… so what should this show us ??
It’s fine in blender and so AE is the problem ??
Hi Okidoki, as i mentioned in the image with the white background, when I import the image without bg and overlay on the white one’ it also appears a strange nuance.
I prefer AE because is easier to achieve a pure white bg instead of using blender whith lighting setup.
On my pc is PNG format, perhaps it changed on website
Did you render with a shadow catcher in Cycles for having that little shadow under the object? If so, your png is populated with shadow pixels and you are going to have a good time rotoscoping that out. If you want to keep the shadow catcher, maybe look into using a spherical gradient as a mask so that it fades before getting to the boundary of your render dimensions.
Hi Craig, yes I used a shadow catcher, I’m not familiar with " a spherical gradient as a mask " do you mind attaching a video tutorial ?
Remove your shadow catcher and render without for a test and see if that doesn’t get rid of your issue. I’ll see if I can make a sample file in a minute.
Yes it works, the shadow catcher was the issue, kind of you
shadow catcher spherical gradient mask.blend (1.3 MB)
Here is a basic version, hopefully it is self explanatory.
Ahhh… so no pure transparent background… and it seems you want to overlay it on a bigger background image which is mostly white ( i thought pure white color 
)…
…and @CDMJ suggestion is intersting… i think i learnt something today… 
Thanks a lot, have a nice day !
