Export of HighRes-PNG *still* without Shadows on V2023 ??

[design]

Hi there,
Using Inventor Pro 2023 i need to export an assembly as an PNG with high resolution (10000 x 5100 Pixels).
(shaded view, all shadows on, textures on).
But: shadows are only exported on the PNG up to 8192 Pixels, above 8193 Pixels there are no shadows anymore.

Anybody told here something about Registry-Keys to change (for Version 2020...) to fix this.
What are the keys and why is it still a problem on the newest version of Inventor???

Help please!

tnx

Clyde

Can't you make a render with that resolution?

[design]

No, rendering is not an option because we use image files as stickers for the front panels and they are not rendered correctly (this is a problem since version 2012...).
I just installed the update 2023.2: no change.
From a size of 8193 x YYYY pixels the PNG loses the shadows.
Error in export filter or error in the programming of the variables!

Can you share the file?

Are you sure about the problem? Look at this thread:

@design 

In your Options, do you have the background set to Transparent?  I exported the same image several times, above and below the 8193 pixels, and neither had the shadow.  I then exported the same image above 8193 with "Transparent" unchecked, and the shadow was there.  IV 2023.1

[design]

I can't provide the original assembly, but it also works with some stupid little part as you can see.

I draw this part, colored it, used shaded perspective view, with all shadows switched to on. 
Then saved as a copy with PNG options 8192x4200, transparency, active components => works!  
Second export, same PNG options, but 1 Pixel larger (over the "8192-border") => crap! no shadows...

?

[design]

I already tested that before (tried with all option on/off on PNG): doesn't change: above 8193 there are no shadows.

(btw: it worked on Version 2019, even with 10000x5100 pixels....)

[kacper.suchomski]

How did you create these images? By what method?

[design]

as i wrote: "save a copy of", used PNG, stored picture to disk.
(I just opened the files in Adobe Photoshop to put them together and resized them for the forum, not that the upload gets stucked with two 8192x4200pixel images 🙂

btw: i just found out (watching your video):the problem with rendering an image only appears, when you link the picture for the sticker. If you attach the picture it works, but then you have to renew the whole part all the time if you update the image-file itself... (deleting picture, get new picture, stick it, render it...). Boring!

[kacper.suchomski]

You can change the photo manually in Inventor or manually assemble it in Photoshop.
You always have to click something.
But I find it worth checking if you can do the render in one go.

[design]

Well Rendering looks good, but is not really an option for us:  
- we store the pictures in 5 different views (different angles)  
- we need to easily update the front-image of our products, so not linking a picture as a sticker takes a lot of update-time (changing drafts)  
- and then: to have a nice rendering (also for brochures) it takes a lot of time, even on a new workstation 🙂 and we are happy for the past years with "CAD-looking" pictures of our products. See them at emc-partner.com

for the moment - UNTIL AUTODESK FINALY GET THIS PNG-FILTER WORKING AS IT SHOULD - I will reduce the pixels to the size of 8192 x 4200.

@design Have you tried File\Export\Image, and then choose .png as they type, an select Options at the bottom.  Might be the same result?

[design]

Yes, I tested both ways:  "save as a copy" and "Export -> Image -> PNG". 
I think, both ways end up in the same "buggy" subroutine 🙂

btw:
I already had problems with this export and stickers years ago:

so I'm getting used to use workarounds... Pobody is nerfect...

Hi! One thing you may try is to use Realistic Shaded View with all effects enabled and turn on Ray Tracing. It will use GPU to compute the view. Then take a screenshot. Does it work better?

Many thanks!

[design]

We are not talking about Rendering here. I already mentioned, that rendering is only possible if you use pictures in decals that are connected with the parts, not linked with them. Any we need to link them, due to frequent updates of the decals.
With linked pictures on decals, Autodesk-Rendering is not your friend. Period.

Let's go back to the real problem:

Fact is:  if you use more than 8192 Pixel in one size of the PNG Export-Filter, all shadows will  be skipped on the generated image! As 8192 is 2^13 this looks to me as a software-error that can be fixed, or an Registrykey-value that  can be changed. Anyone from the developper-team knows how to do that, or where to do that?
And why is there a limit anyway? 

And as i mentioned before: it worked on Version 2012...2019 (didn't use 2021).

@design @johnsonshiue 

I've still been unable to duplicate the issue, even at 10000 px x 8000 px.  I've tried with multiple view settings; Shaded, Realistic, etc.  Scratching my head, trying to figure out what could be the cause.

Is there any possibility that you could create a very small dummy assembly that behaves this way for you and then Pack and Go and share it here so we could test on your assembly using the same workflow steps?

[design]

I attached a small dummy-part (see thread above, about 5th message) called "Test-Export-PNG (Inventor-2023-2).ipt" that I used to try, if it is just a problem for assemblies or for parts only. Well it is on my side: even a simple part like the attached one won't be exported with shadows, if it is bigger than 8192 pixels.

@design 

Sorry,... found it.  this thread is getting a long tail!  😂

One more question,... what lighting style do you typically use, so I can try to replicate everything the way you have it set up?  So far I have Perspective and All Shadows.  Visual style is Realistic.  

EDIT:

@johnsonshiue  I have been able to reproduce this.  It is the Ambient Shadows that do not get created over the resolution threshold mentioned above by @design .

Well, I tried to do a Pack'nGo from the dummy part.

For the setup:
I use shaded view (not realistic), use all Shadows, no reflections, perspective, and used the attached light style for illuminating specially the front-plane of our HV-Generators.

I put again an example of one of our Accessory, one exported with 8192x5100, one with 8193x5100 pixel to show you the difference (both pictures has been resized for upload).

btw:
my Systems are a HP Z640 with Nvidia Quadro 5000M (Win10pro 21H2) and a new installed HP ZBook-15 Power G8 (Win11), both wit Inventor Pro 2023, 64bit, Build 271, Release 2023.2
and the problem is the same on both machines.
