Photoshop Activity – Slicing Images for a Seamless Set Background

Please check the calendar to see when this workshop is next scheduled or contact EvaHarley inworld if you are interested.  Harleyquin Calendar

Workshop Overview:

This workshop will be focused on using the Photoshop slicing and cropping tools to create a seamless background for your multi-walled set.  Slices can also be used to create textures for your sky and floor.  Don’t use Photoshop?  That’s ok!  Look up how to slice and crop for the software you use and follow along!  During the workshop we will be slicing and dicing, and I will be providing tools for calculating image sizes for non-standard stage blanks.

** Requires Photoshop to participate for special slicing tool features.  If you use another program, be sure to know the basics of slicing and cropping in your own program to follow along.  All are welcome to listen.

Workshop Flow:

Class Materials Provided:

  • notecard with a link to an image to download
  • a “mini” stage blank – exact proportions of a standard stage size, miniaturized
  • notecard with how to calculate image sizes for each wall and a google documents link to a spreadsheet that can help you do this automatically for non-standard stage blanks

Special note:  There will be 30L in SL fees required for uploading your sliced images.  I will be providing this amount to ALL participants on a building pad during this part of the exercise.  There is a workshop contribution bowl if you’d like to make a contribution but there is no obligation!  Contributions are greatly appreciated to support expenses but never required or expected.


  1. Open your image editing program
  2. Download the image provided to you via a link in the notecard and open the image in your program
  3. Review the location of the slicing tool and the cropping tool in your program


  • Before and after view of a single image sliced to texture a set seamlessly
  • Why????  Why slicing images can provide you additional options for amazing sets
  • Considerations when choosing an image
  • Potential solutions for “stretching” and flipping an image when necessary to make it work (these actions will be briefly mentioned and covered in a separate workshop)
  •  Preparing your set blank, cleaning up overhangs.  Edges must line up for a seamless look.
  • Focus on 3 slices – side walls and back walls
  • Reviewing slice sizes.  Standard sets are 25%-50%-25%.  Easy way to check, and what to do when it’s not standard.
  • Slicing time!  Using the tools to create your slices – slicing wizards and manually slicing.
  • Crop and save time – left, mid, and right walls.
  • Upload and apply.  Bam!
  • Discussion on slicing for floors and ceiling with examples.
  • A brief mention of texture offsets.
  • Open discussion, alternatives, and suggestions.

Jump Start:

Helpful things to know if you’d like a bit of a head start.

This workshop will be geared towards Photoshop users but users of other programs will still be able to follow along.  Photoshop is a very powerful too, and a cloud version is available if you don’t want to purchase the software.

The Creative Cloud license allows you to install Photoshop and receive free updates for as little as $9.99 per month.  This is the option I’ve chosen.  If you are a college student or teacher, you may be eligible for additional discounts.

No matter what software package you use:

  • Open your image editing program and know how to open an image
  • If you are not using photoshop, use google to search for “slice” and the name of your image editing program.  Many programs have this feature.
  • If you are not using photoshop, research how to crop an image if you’ve never done this before.

If you are having issues finding these options, please contact EvaHarley at least a few days before the workshop with the name of your software and I will post screenshots here.  Thanks!
