Alpha channel doesn't work anymore


(Mfhammer) #1

Beneath my models I made some shadows with a baked shadow with (alpha channel) transparency.
In edit mode it looks okay, but in view mode it's not, what has changed sketchfab?

disable transparency: transparent: 1,
Blending transparency stopped working with transparent background.


@mfhammer Yeah, it looks like we introduced a bug. Investigating! ( @stephomi )

@MadalinBerechet Sorry I'm not sure what you're talking about.

I have a furniture model "side table" where the floor is a plane mapped using a transparent png (a baked map):

I am loading the model using initialization option: transparent: 1, and overlaying on a still image (augmented reality like)

Blending transparency, which has worked so far, doesn't work anymore.
I've tried both transparent: 0 and transparent: 1 initialization option parameters.

@mfhammer It's a known issue. A fix is on his way, sorry for the inconvenience.

@MadalinBerechet Can you provide an url? We can't reproduce your issue.

(Madalin Berechet) #6

this is the link

Please see on "Background" tab, where the 3d model is overlaying on a still image.
Also visible on loading (some blinks).

I am not changing that transparent map on runtime.
The map is defined in Sketchfab editor as a transparent - blending (not mask) texture (transparent png file)

I see thanks, it's another issue but it'll also be fixed on the next release.

Thanks Stephomi, James for the reply, can you tell me when it's planned or when this issue is solved, for the meantime I put out all of the shadows in my models because I use sketchfab within my webshop.

@mfhammer Unless there is an issue, the fix should be live in a few hours.

Fix is live!
