Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

4.5 UMB border image brushes ignore UI scaling

As the title says. Brushes set to "Box" properly scale up along UI scaling when you select different preview screen sizes, but brushes set to "Border" always render at 1:1 pixels.

Hello pedro_clericuzzi,

I will be more than happy to assist you, however I will need additional information.

Quick questions:

  1. Can you provide a screen shot of the issue you are having?

  2. Can you explain further what it is you mean by setting your brushes to "Box" and "Border"?

  3. When you say preview screens are you referring to the resolution drop down?

  4. When you say that it scales 1:1. Do you mean according to screen size, original image size, preview screen size, or other?

  5. Can you explain what you mean by proper scaling and what the expectations of proper in tell?

Any additional information you can provide would help to narrow down the issue you are having.

Can you provide a screen shot of the issue you are having?

alt textalt text

The Image on the left has the brush Draw As set to "Box", the one on the right uses "Border". Both use the same texture and margin settings. I have an UI scaling curve set to 0.9 at 768 and 1.8 at 1536.

Can you explain further what it is you mean by setting your brushes to "Box" and "Border"?

It's the "Draw As" setting:

When you say that it scales 1:1. Do you mean according to screen size, original image size, preview screen size, or other?

Brushes with Draw As set to "Border" seem to always draw at 1:1 pixels to the screen. Even zooming in/out in the UMG editor is enough to view the problem: the border ignores the zoom and always renders its brush at 100% scale. The same happens if you wrap it around a ScaleBox: the Image size changes, but the border brush always keeps the same size relative to my monitor.

Any news on this? This is still happening as of 4.9.2. It makes the "border" "draw as" setting unusable on mobile, where dpi scaling is absolutely necessary.

This is still an issue as of 4.13, is this expected behavior? Does a work-around exist?

avatar image Rudy Q ♦♦ STAFF Jul 24 '17 at 06:09 PM

Hello RMMedia,

There was an update, the customization for the FSlateBrush to automatically keep the margins set correctly. At most they can allocate 0.5 across all values, if left is 1, right must be 0, if top is 1, bottom must be 0. If you attempt to set them all at once, by setting margin to just 1, it will fallback to 0.5 or all of them. I hope that this information helps.

Make it a great day

This is still an issue in 4.17

This is still an issue in 4.22. Border drawing is flat out ignoring DPI scale. The issue UE-4630 was marked as "wont fix". Unbelievable.

I can't believe borders are still unusable in 4.19.2, even just zooming out makes them larger and larger.
