So, there's a “big” problem with vector costumes… Literally. When resizing a sprite using a vector costume (In the coding, not the costume editor), it doesn't work like vectors are supposed to. For some reason, it's blurry and pixelated, instead of retaining the infinite curves that it should have. This happens on ALL devices and makes a huge impact on certain games such as GSE. I'm not even sure if this is a bug, it could just be bad design… Point is, these vectors simply aren't true vectors. PLEASE, fix this.

CNR, resizing looks and works fine. Used both Scratch Cat and Candi from D_i_a_v_l_o's (she was the first vectorist that sprung into my mind) project entitled The Wand || Episode Eight. My browser / operating system: Windows NT 10.0, Chrome 73.0.3683.103, No Flash version detected

Try going into the code and just do something like

set size to (300) %

And you'll see what I mean when previewing the project. The sprite you changed the size of should have lessened in quality.

Still CNR, there's a second of blur in full screen, as expected from anything. However, after a second, everything works fine.

Just had a bit of a play with this

Resizing the cat looks “OK” down to about 50% but deteriorates at 40% and below

This is in editor mode with normal screen

If I switch to full-screen, its looks fine at any size down to 20% - after that its start to deteriorate as well

Was the sprite a vector?

No- size it UP. Here… https://scratch.mit.edu/projects/74711180 Play this, the level should be blurry due to the sprite size being set all the way up to 900%

Yep, it was Scratch Cat and Candi that I both used.

I can't get your project to load

But when I resize up the cat to 300 or even 900% - it looks fine - even on standard editing screen

It might just be your mouse, i bought a new mouse and vector works normally now, it's fine. Do you have a mac mouse? If you do, you would need to change it…..
Try just taking a little longer. I make icons, but i found it like you are saying, once you do it loads, you will get the hang of it, and it will hopefully work!

Hope that helps,

And what exactly does the mouse have to do with this?

I can say that this also happens to me. If I resize a sprite to a size that isn't divisible by 50, then it looks as described by OP.

This made massive objects and such in my “Overcomplicated Physics Engine” project seem blurry, when the entire reason why people use Vector sprites is to have infinite resolution.

I think this might be because Scratch is first converting the image to a really high resolution bitmap, then scaling it, applying visual effects, then rendering it. A fix might be scaling it before converting.

Finally, some people who actually know what I'm talking about.

For those who still don't believe that this is a bug, try resizing any vector sprite to 2000% and you'll see what they're talking about.

2000% is overkill, even for a sprite that 1x1 pixel.

Any way to trigger this bug on a more reasonable scale?

1000 percent or even just 500 would do the trick. Of course, there is the size limit, but it can be bypassed if you have one blank costume, then do this:

switch costume to [blank]

set size to (1000) %

switch costume to [not blank]

I'm pretty sure the fact that the other people didn't do this trick to bypass the size limit is the reason why theirs looked fine.

(quoting myself from another topic)

This is just my guess, since I don't have the know-how to look into the rendering code myself, but I'm assuming that the entire screen is rendered as a single image each frame, with the resolution scaled to match the user's monitor. This would explain why vector graphics in projects appear crisp in the normal window, but blurry when viewed in fullscreen mode.

Again, this is just my guess, so I could be wildly off the mark.

For me, the assets still look blurry when windowed. And I'll just say it again: For a great example, play Genesis Sonic Engine by tomicool, the stage sprite is upscaled to 900%. And if anyone tries telling me that somehow is still not blurry, then no. You're lying.
(please note that the last part of the comment was a joke.)

This bug occurs even on 400% in https://scratch.mit.edu/projects/282544403/editor/
