Many people ask me how I create such neat retextures on ROBLOX. Since it is very difficult to explain in text, people are often deterred. However, having your work featured in the ROBLOX catalog isn't as hard as it seems! ** I apologize for any bad image quality. I cannot prevent it! :( **

Step 1: Find an Item to Retexture

In order to begin retexturing, you must find an item to retexture; from there, insert it into an instance of ROBLOX Studio in which you have access to Explorer and Properties. To do this, use either Free Models, execute an InsertService script, or wear the item into the game. For all intents and purposes, I will be retexturing the Red Stetson hat.

Step 2: Find the TextureId

In order to find the texture, you must have Explorer and Properties open. If you don't, click View > Explorer and View > Properties or ask the forums. The TextureId is located inside the Mesh object inside of the item's handle.

Step 3: Locate the Texture Image

Now that you know the item's TextureId, you need to find the picture. Here's how: copy the numbers at the end of the TextureId, open an item in the Catalog (such as the hat or gear itself), and replace the numbers at the end of the Catalog item with the TextureId's numbers. You should land on a 2D rendition of the item you decided to retexture.

Step 4: Edit the Texture

Now that you have the actual image, it's time to retexture it! Copy and paste (or save and open) the picture into your favorite image editor. For this tutorial, I'll be using paint.NET - a free and awesome image editor. To get paint.NET 3.5.10 (the latest as of when this Instructable was created), click here. Change up the image as much as you'd like -- try to keep in mind what it will look like in 3D.

Step 5: Publish the Texture to ROBLOX

In order to publish the texture to ROBLOX, you need to create a Decal. To do this, go to My ROBLOX, Stuff, and Decals. Click Create New. Find the file of the texture you were editing, and upload it!

Step 6: Load the Texture to the Mesh

Now that you have the texture in a Decal, you need to go back to the place that has the original hat in it. In Toolbox, go to the My Decals section and move the Decal to the hat. Remember when we were working with the TextureId? We're going to again -- this time, with the Decal's. Copy the ENTIRE THING and replace the Mesh's current TextureId with it. Congratulations -- you've just created a retexture.

Step 7: Publish the Retexture!

You've just created a neat new retexture -- now it's time to publish it and let the community see! First, select your retexture. Then, click File > Publish Selection to ROBLOX (or, ask the Forums!). Be careful not to click the plain "Publish to ROBLOX" option, as it will edit one of your Places. A new dialog should appear. Click Create. Edit the title and description to your liking (I'd recommend checking "Publish for free public use" to allow people to take the Model); then, click Publish! Voila; you've just created your first retexture!

Step 8: Stop Copiers!

Remember that Decal you created? Any user can now use that and take credit for the retexture! Since ROBLOX saves an Image of the texture, click Delete From My Stuff on the Decal you created to prevent people from copying the image easily. I can't tell you how many times I have deleted the Model of the retexture; be extra careful to make sure that you are deleting the Decal!

Step 9: Share Your Work!

Now that you have successfully created your retexture, it's time to share it with the world! Create a new Forum Thread here! Also, I'd really like to see what you guys have come up with! Send me a Private Message with a link to your retexture! Happy retexturing, guys! :)
