How to integrate scaled 426x240 pixel art assets properly into Defold Engine

When scaling legacy retro sprites up to larger resolutions, default image encoders can cause unwanted blurring. By scaling up to exactly 4x dimensions via hard index mutations, asset structure remains pure and ready to drop directly into production workflows.

💡 Professional Pro-Tip for Defold Engine Developers:

Set your engine workspace assets window to toggle game.project -> Graphics -> texture_sampling: nearest active. Disable global Subpixels toggle to force sprite vertices to physical integer coordinates. Keep Sprite Trim Mode turned OFF for accurate Slice-9 layout math.

Frequently Asked Questions

🤔 Why does asset upscaling in Defold produce blurry lines on High DPI displays?

Defold's High DPI mode renders to a high-resolution back-buffer that clashes with standard continuous texture samplers. You must navigate to your game.project settings, change texture_sampling to 'nearest', and systematically disable the 'Subpixels' option to keep vertices locked to pixel units.
