As an avid Roblox gamer and developer with over 10 years of experience, I‘m thrilled to share this epic 2,000+ word guide on working with one of my favorite Studio features – decals!
Decals allow importing custom images to use as textures and designs on parts in your Roblox worlds. Taking the time to create, properly implement, and optimize decals can massively level up your games‘ graphical quality and visual flair.
Through easy-to-follow steps, expert technical insight, and my own maker passion, I‘ll teach you everything you need to know to craft incredible decaled creations guaranteed to impress players.
Let‘s get started!
Step 1 – Prepare Eye-Catching Decal Images
Before bringing images into Roblox Studio as decals, it‘s really important to start with well-made source material. As the saying goes – garbage in, garbage out.
Some key image attributes to aim for include:
Resolution – For clean graphics at any size, make decals at least 512×512 pixels. Go higher for best rescale quality.
Dimensions – Square images work best, but rectangular decals can enable more interesting textures.
Color Depth – Stick to 24-bit RGB color for widest game engine compatibility.
File Size – Keep images under 500KB each for performance. PNG compression can help optimize.
Transparency – Use PNGs with transparent backgrounds to seamlessly integrate decals onto parts. This prevents ugly white boxes around your designs!
When making your own decal imagery, also leverage helpful tools like:
Canva – Web app for easy graphic design with tons of templates
GIMP – Free advanced image editor similar to Photoshop
Procreate – Popular digital illustration software with great brush tools
Labelbox – Machine learning platform to automate transparency creation
Check out this gallery of awesome custom decal examples made specifically for integration into Roblox games:
With so much creative potential, don‘t be afraid to experiment with different decal content like:
- Thematic texture maps
- Backdrops and environments
- repeating patterns
- special effects
- interactive touchpoints
Now let‘s import your decal imagery into Roblox Studio to really make magic…
Step 2 – Importing Decals into Studio
With well-crafted decal images ready, importing them into your Roblox game is easy. Just follow these steps:
-
Open your game in Roblox Studio
-
Click on the "Model" tab
-
Select "Inventory" from the left menu
-
Choose the "Decals" inventory section
-
Click the "+" button to upload images from your computer
-
Select each desired image file and Open to upload
I recommend compressing images before import to optimize file performance:
MyDecal.png (Uncompressed - 1.5MB) -> MyDecalCompressed.png (Compressed - 250KB) Also, rename each decal on import for easier organization:
Right click decal > Rename
CityMuralDecal.png > CityMuralOnce upload is complete, give Roblox 5-10 minutes to process your images. Soon you‘ll see them loaded in your Decals inventory, primed for insertion onto parts!
Step 3 – Adding Decals to Objects
With decals uploaded, it‘s time to put them in your game! Here is the process for mapping an image onto a part:
-
Select the target part for decal placement
-
Access the Properties menu (Right click part > Properties)
-
Click the circle icon next to the "Decal" property
-
Choose your imported decal image from the menu
And done! You‘ll now see the image appear on one face of the part automatically. It will stretch/squash to map cleanly based on surface area.
You can further customize decal settings like:
StudsPerTile – Determines how the image fits across a part face
Transparency – Controls decal opacity from 0-1.0
Facing – Defines which axis the image faces outward on
Get creative combining decals with unique part shapes to make magic!
Now let‘s take full control over decal positioning and scaling…
Step 4 – Positioning & Resizing Decals
While automatically applying decals is great for rapid development, you‘ll often want more precision over their location and size.
Roblox Studio provides various transform tools to manipulate placed decals exactly how you like:
Position
Use the Move tool to shift a decal between different faces on a part. This retains proportions based on the face dimensions.
You can also directly enter coordinates to place a decal precisely in 3D space:
Decal.Position = Vector3.new(2, 3, 5) Scale
Resizing a decal is trickier than parts since it risks warping/pixelating the image badly.
I recommend manually scaling clustered collections of parts grouped with your decal instead. This maintains clean graphics at any size!
To demonstrate, check out this decal scaling example model:
Grouped parts keep the mural decal‘s proportions perfect when resized!
For more advanced techniques, leverage custom plugins like RoScale which can manipulate decals more precisely.
On to optimizing performance…
Step 5 – Decal Performance Best Practices
While beautiful decals can make your Roblox games stand out, beware going overboard! Too many high resolution images can hurt game performance, especially on mobile devices.
Follow these optimization tips:
File Format
-
Use PNG instead of JPG to allow transparency at lower file sizes
-
JPEG works for non-transparent decals
| Format | Transparency | File Size |
|---|---|---|
| PNG | Yes | Smaller |
| JPEG | No | Bigger |
Image Resolution
-
Scale back decal dimensions if your game is laggy
-
512×512 offers nice balance
Limit Decal Count
-
Keep total decals under 50 for smooth gameplay
-
Reuse decals as much as possible
Compress Images
- Use TinyPNG and similar tools to shrink files sizes
Following these best practices from day one will ensure your visua design never bogs down gameplay for players!
Now to put the finishing touches on…
Step 6 – Playtesting & Publishing
Before unleashing your decaled creation onto the Roblox metaverse, be sure to thoroughly play test within Studio first:
-
Click Play to preview your game
-
Run around checking for visual issues with decals – Do they display correctly from all angles? Any odd overlapping or clipping?
-
Verify seamless integration into the parts – No visible edges between decals and base objects
-
Check graphics on different quality levels from low to high
I also recommend closely reviewing Roblox‘s Avatar Content Policy around visuals to avoid issues:
Once any final tweaks are made, it‘s go time – Click File > Publish to Roblox to share your decaled creation with the world!
The publish process will likely take a bit longer than normal due to all the image data being transferred. I‘d give it at least 10-15 minutes depending on file sizes.
Soon your unique decal implementation will be live for all to enjoy!
Unlock Endless Possibilities with Decals
Congrats, you made it to end of the ultimate decal guide! Let‘s recap the key pointers:
