I decided to write this post after receiving a reader’s question on how to upload files to make into a completed skin in OpenSim. My reply included a description on how to do this, but I think it’s something that needs an expanded post.
I learned how to upload files and make a wearable skin in Second Life; it is one of those areas where an assumption is often made that everyone knows how to do it. To help those who haven’t put together an avatar skin before I’ve written this tutorial.
The same basic method applies for other grids and viewers (as far as I’m aware).
I’m using the Starlight skin .psd files made by Eloh Eliot and working in Photoshop CS3. For OpenSim I’m using the Imprudence viewer.
This tutorial is for people who have some Photoshop experience rather than the complete beginner.
When you are happy with your skin and want to upload it take the following steps:
1. Check the image size of your Photoshop files. If they are set at 1024 by 1024 pixels you’ll need to resize them. You can upload this size but it will make a large file, which is not very efficient, and could be slow to rez in-world.
2. In the Image Size dialog box resize the Face, Upper and Lower Body files to 512 x 512 pixels. (Image 1)
Then go to Save As and save the Face, Upper and Lower Body files as Targa (.tga) format. (Image 2)
The next dialog box to open will give you the choice of saving as 16, 24 or 32 bit (Image 3). To make sure that the Face file is uploaded with the transparency information, select the 32 bit option. You can save the Upper and Lower Body files as 24 bit – if you have not added any Alpha Channels when modifying the files.
Face/Head template files usually contain an Alpha Channel and only Targa (.tga) and Portable Network Graphic (.png) file formats are available in virtual worlds to recognise the transparency information. People also use the .png file format for saving skin files. I use Targa as that’s what I’m familiar with but it’s what works best for you.
3. You do not need to save your .psd files at the 512 x 512 image size. If you are using the original files, and not saved copies, I’d recommend against it. If you want to come back and make changes, or create a new skin, it is harder to do detailed work at this smaller size.
4. Now that your files are saved it is time to upload them. Login to your grid or region and find your favourite spot to do some appearance editing.
Uploading and making your new skin
1. Go to File, then the Upload menu, select Upload Image and choose the Face, Upper and Lower Body .tga (or .png) files. (Image 1)
Depending on your viewer, you can choose to do a preview of each file before you upload it. To look, go to the ‘Preview image as’ and then use the drop down menu to see the file as it will look on an avatar. (Image 2)
Those with free uploads, or viewers that have free temporary uploads, can skip the preview if you wish. Once the files are uploaded they will be saved to your Textures folder.
2. The next step is to make a new skin. Open your Inventory window and go to Create, located at the top of the window. Select New Body Parts and then select New Skin. A new skin will appear in your Body Parts folder. Rename the skin as you choose, then double-click or Command click (Mac)/Right click (Windows) on the name to wear it. Don’t panic on finding that it is a default Ruth skin! The next steps should fix that.
3. When you’re wearing your new skin go to the Appearance window. Choose the Skin tab listed under Body Parts. (Image 3)
The Skin window will show three grey boxes with a black cross in them, on the left hand side next to the sliders. These are the Head, Upper Body and Lower Body Tattoos. This is where you will assign your uploaded skin files to the new skin you’re wearing.
Make sure you have the ‘Apply Immediately’ box ticked, so that you can see the files as they are applied to the skin. Click on the Head Tattoos box. Another window will open where you can look for the uploaded skin files in your Inventory. Find the Face upload, click on the name and then click on the Select button. Now the upload will appear in the Head Tattoos box and on your avatar skin.
Repeat the same process for the Upper and Lower Body boxes and then press Save. You will now be wearing your new skin with the uploaded files.
I hope that this will be of help. Enjoy your new skin!
