White Halo in Image Props without background or White background

[erminio]

Hi everyone
I have to submit a question about an annoying white halo appearing in image props, when rendered without a sky background for photo insertions pourpose
As in the linked image, when a colored background is applied, the white halo disappears, so it isn't a matter of alpha quality
This problem started with Vectorworks 2022 and has not been solved yet

I've done dozens of tests with similar results

No matter the quality of the starting image nor the render type or quality

 

Maybe I'm wrong but I've not seen previous posts matching this problem
Any help will be appreciated

 

Thank you for your time

Here’s another recent thread which discussed this issue:

Thank you rDesign

I've seen that, but it seems to be a slightly different thing and anyway the problem has not been solved

Unless I am misunderstanding your issue, It works fine when you use good quality image props....

 

The testtrees.PNG was created using "export image" from a sheet viewport.

screenshot....png is a screen shot of the same.

testtrees-affinityphoto.png was created by opening testtrees.png and inserting a black background.

 

RGB items are simple extrudes the white "background" is nothing, just the typical vectorworks environment.

Thank you for your interest Jeff
Let me understand: are trees rendered Image props or simple PNG?

Which Vectorworks release have you got? If 2022 or later could you please attach your file?

 

As I wrote, the problem is not the quality of the image, since the same image props worked fine till Vectorworks 2021

For a period I had to work with 2022 and finally export in 2021 for final rendering, but now I don't have 2021 installed any longer

 

I'm attaching my test file in 2022 version, created in 2023 and exported

You can also find the original PNG image

The trees are built in vectorworks trees composed of imageprops

That was made in V2023, I still have V2021 & 22 installed too.

 

I opened your file in 2022 and updated the viewports.  Everything looks normal to me without changing any of your settings...

Thank you Jeff

This is really weird

Have you seen the white halo before re-rendering that?

I've put a magenta rectangle back in your viewport and everything was good

 

I've re-rendered the same VP with no changes and got the usual white halo again

Just one thing

I see you've got also Vectorworks 2023

Do you encounter the same halo in 2023?

I have not experienced this problem in any version.  Have you searched these forums for similar problems?  I wish I could help you, perhaps a call to tech support is in order?

There was at least one in depth thread about that exact issue.

AFAIR there was also a solution/workaround or SP time frame,

but I forgot.

[rDesign]

I found another thread which describes a similar issue, perhaps this is the one @zoomer was trying to recall?
 

It’s strange that the appearance of the white halo is not consistent. I would send in your file to tech support.

It seems that no others is experiencing that problem
This is even more weird

 

I'm just wondering two last things that could differ

 

1  I own an italian release

I've sent a file with a description of the problem last year to italian distributor
I think they've sent to NNA

2  I'm working on a silicon mac

Passing from an Intel, work is faster, but less stable in my opinion

Thank you rDesign

This gave me more tests to try

 

I tried to uncheck the option "None fill uses alpha transparency" suggested by Panzer, but didn't solve

Neither solved removing reflection from the image prop suggested by zoomer

 

Is this post enough to start a bug ticket?

Point 2 is the answer!

I have installed Vectorworks 2023 on the "old" iMac with the same Ventura OS and the halo disappears

So it really seems to be a question linked to Arm processors

Thank you everyone 👍🏻

@erminio I too just did a quick test and discovered a few things...I have an iMac Pro.

I believe one reason you saw the 'halo' is because the viewport had a 'none' fill...

Check the screenshot . Perhaps this will help.

I attached the  2022 file.

Thank you Kevin

Didn't know this trick!

However I do need a VP without background in order to make a post production in Affinity Photo

I think that if you re-render this VP you'll see the halo disappear, since you have an Intel based Mac
