Frequently Asked Questions
Professional answers to common questions
Is Blue Marble malware?
No. Blue Marble does not contain malicious code. The Blue Marble source code can be found in the
src/ folder on GitHub.
If you're concerned about security, you can read the code and bundle it yourself using the tools in
build/.
Why are some pixels not showing on the overlay?
This usually happens if the template image is not converted to the Wplace color palette. You should convert your template using a color converter for Wplace or manually adjust the template image to match the Wplace color palette. Also check that no pixels are disabled in the filter settings of the Blue Marble menu.
How can Blue Marble place pixels for me?
It can't. Unfortunately Blue Marble will not support the automatic placement of pixels without user interaction because it is not allowed by Wplace. Blue Marble is a visual assistance tool only.
How do I hide the overlay?
You can temporarily hide the overlay by clicking the "Disable" button in the Blue Marble menu. If you want to completely remove both the overlay and the Blue Marble menu, turn off the userscript in Tampermonkey and refresh the page.
How do I tell colors apart?
Find the color in the color filter list and click the checkbox to turn the color on or off. If you want to work on only one color at a time (recommended), click "Disable All" in the color filter, then enable the checkbox next to the color you want to place. This way only one color on your template will appear at a time.
How do I get the color of a pixel?
Use the eyedropper in the palette menu of wplace. If your template colors match the wplace palette, you can select the template pixel dot to get the template's color for that pixel.
Why do game notifications appear on top of the overlay?
Game notifications only appear when they need immediate attention. Therefore they have priority over the overlay (which typically needs no attention).
Can I use this on mobile devices?
Yes, Blue Marble has been verified to work on mobile devices. The interface adapts to smaller screens while maintaining full functionality.
What image formats are supported?
Blue Marble supports PNG and WEBP formats with transparency. These formats provide the best quality and flexibility for template overlays while maintaining small file sizes.
