Blueprint failed to publish to Steam Workshop

Grant Herin shared this bug 10 months ago
Investigating

Hello KSH,

I am experiencing a bug where after clicking Publish in the blueprint menu I amgreeted by what looks like a half-loaded screen with a checkbox "Exploration", an OK button, and a Cancel buttton. If I click OK, I am met with a ""Failed to publish to Steam Workshop" with the header "world publish failed". I have tried everything on similar bugs, but nothing's working forme. I am sorry for any spelling/grammar errors as the t description text box does not display text as I'm typing it, only when I save it. I am on Version 1.190.0 of SE.

I have this exact same bug. It has been consistent in all versions for me.

I've tried everything possible to fix this with no success.

i had this same bug now for a while and i can only seem to fix it by removing the image from the folder before publishing

it seem if the pic = a size of around 800kb or larger it fails to publish


this also seem to affecting Mods as well.

i think its realted to steams new Pic limits maybe

Confirmed, Steam has reduced the allowed file size for the picture to 1 Mb. Unless Keen changes the way in which the attached picture of the Blueprints that are made, we will continuously have to convert the image to .jpg to a size less than 1 Mb manually.

same issue, only uploads if i delete the thumbnail and upload without a thumbnail, which deletes the purpose, im no noob to uploads either, i have 30+ frontpage builds....... yes thumbnail is below 1MB, tried below 500kb, even tired 1kb thumbnail, nothing works. i tired JPEG PNG nothing changes, still get the failed to upload error

Same as Andrew. Even from a fresh windows install and SE install.

I have the same issue too, multiple of my blueprints either new or old can't be updated or published.

Just posterize the image (limit the number of color levels) before saving as PNG.


Start with 64 levels per channel. If file size is above 800kb, then decrease the number of color levels by 8 and try again. I usually don't have to go down further than 48 levels, but most screenshots can fit with 64 levels easily.


It results in very minimal human visible image degradation on the Steam Workshop UI, only some smooth gradients suffer from it. It is very easy to implement.


Until then the workaround is to open the thumb.png in Gimp, use the Colors / Posterize filter to reduce the number of colors, then export back as PNG overwriting the original file. Undo and do it again with less color levels in case the PNG is still too large.

This may be some larger issue, I've checked all of my images and nothing goes over the 1Mb limit, and now it gives me a message of "Make sure steam profile is signed in", when, in fact, my Steam profile is very much signed in. I've also noticed that when Steam Cloud is enabled, I cannot blueprint anything at all. This problem still persists on the most recent update of SE at the time of writing this.

Then I guess there are two separate issues here. Size of the thumb.png file and something with the Steam login.

Also, the file size limit does not seem to be exactly 1MB, because it failed to upload a nearly 1MB image for me earlier. This is why reducing the size to around 800kB is safe.

Hello,

Thank you very much for your feedback.

Please, can you provide zip of BP which cannot be published? It would help a lot.

Thank you and have a nice day :-)

Please find it attached:

  • Blueprint exported
  • Game log and configuration files
  • Screenshot of error in-game
  • Screenshot of broken private item created on Steam Workshop as a result

Bonus: Try the blueprint in creative mode against a ship/base from at least 100m distance. :)

Thank you very much!

The issue has been reproduced and reported :-)

Have a nice day :-)

Ok, so I guess Steam doesn't like thumbnails at all. Deleting the thumbnail allows me to publish. Idk if this is a "fix" per se, but I can upload now.

You can add the thumbnail on Steam Workshop after publishing as a workaround, until Keen fixes thumbnail compression in SE client.

I was able to publish some of my blueprints by creating another blueprint from a blueprint that failed to publish

(i hope that wasn't confusing) Just putting this here if this can help others.

@younmcmahon That happens when you create the second blueprint from a (slightly) different viewing angle, so the resulting thumbnail image contains less information, thus can be compressed to a smaller size.

For example, in the first case you had objects/asteroids/planets in the background, while in the second case you made a "cleaner" shot by having only space in the background.

There is a similar effect if you have the second shot farther from your object, so it appears to be smaller, thus covers a lower number of pixels, which means less information to compress.

Was this your case?

If you still have both local blueprint folders on your machine, then you may compare the thumb.png file sizes in them.

Oh i see, well thank you now i understand the issue a bit more, but where can i lower the thumbnail size?

At first i tought it was something to do with the remote control block, because most of the blueprint that i failed to upload are remote controled.

Any progress?


Please reach out 1:1 if you would like me to fix this bug.


(rant) SE is losing a ton of well designed ships on the Workshop every day because of this relatively simple issue is not being resolved yet. I've just explained the above workaround the 10th time on Discord to a fellow engineer. Community support is nice to have, but should not be wasted on easy to fix bugs. Jut my 2 cents... (end of rant)

Or just remove thumb.png from the blueprint's folder, publish it from the game, then go to Steam Workshop and add a thumbnail manually. It is cumbersome, but seems to work reliably.

No... Unfortunetely not much progress on my end but thank you nonetheless for the help i'l figure this out at some point :)

That "Any progress?" question was targeted to Keen.

Ah! My mistake then.

I'm still a novice at image manipulations I don't understand it fully just yet.
