Viewer bugs in Shapediver

After extensively tweaking the viewer to have better rendering quality, we got it to a very good state, but there are still 3 things that are bugs:

  1. Lighting settings change when adjusting a light parameter

Take a look at the attached .gif recording. If you change the material the lights have a certain look. Then I minimally change any of the light parameters and the light changes dramatically. It’s like some settings are only updated once I touch one of the parameters. As soon as I change material or the geometry it is back to a different state.

  1. HBAO rendering bug

We would like to use HBAO ambient occlusion, but there is a very visible rendering bug. See the attached image.

  1. Extremely low edge quality in some browsers/on some computers/phones

Not sure how or why, but on some machines or phones the mesh quality around the edges is extremely poor. We have not yet figured out a pattern on where this appears, but it looks very bad. On my machine for example it looks absolutely fine.


Hope we can get those last things sorted.

I cannot open the gif link from your first point, could you please check it so I can review this bug?

For the two other points, it would help if you could give me a link to the specific model and settings causing your issues. Is the AO bug happening when you are using the custom orthographic camera? For the third point, on which devices precisely do you experience the poor rendering?

@mathieu1 did you get my message I sent you with the links you asked for. Any news on this?

I will review your private message and get back to you here once I did.

@mathieu1 Getting such shadow bugs in the viewer on Mac when using Safari and Chrome; on Firefox, it works fine. On Windows also, everything looks fine.
These three images have different shadows setup in Shapediver settings.



@seltzdesign The video you sent me in the PM does not play for me. Therefore I still do not have a was to reproduce or understand the first issue from your message.

Regarding the HBAO issue, our team could reproduce it and will fix it in the upcoming viewer release.

Regarding the low edge quality issue, we could not reproduce on any device on our side for now. We will keep trying to find a configuration where this happens.

@artmachines Could you send a link to your model where the shadow issues appear? We need to know precisely which viewer settings are being used.

Here is the link:

On Windows, it also has some almost invisible shades on the ground plane.
