Understanding Opacity

Back

The process of cutting out black and white.

Before we start with making our tattoos You first need a little understanding of Opacity mapping. Assuming you already have some knowledge of the previewer and texturing a product…then this is the next step.

The easiest way to explain opacity mapping …is to have white where you want your item to show…and black where you want it to disappear. It is simply the process of cutting out shapes. Opacity mapping is used in imvu for a great range of items….going from clothing…to hair…rooms and furniture also. So it is wise to start getting some basic knowledge of how opacity works.

There will be 2 texture pics used always when working with Opacity…….The first is your Diffuse color….this is the main texture that you want to have “show up” on your product…..so if you want your tattoo to appear green on your skin….you would make this a green texture….if you want your tatts to be black….you would make it black…and so on.

The second texture you will use is your opacity….this is where the main work begins…..whatever you have white on this texture pic….is what will make the first diffuse color show. And whatever you have black……will disapear.

if this opacity texture is any shade of grey…..your first diffuse color will appear opaque…… semi see though. It works on a scale….if your pic has light grey on it….the tatt will come out a dark grey…or slightly lighter black……

That is where the Opacity mapping name comes in. Here is an example that may help you understand a little better… Hover over the buttons to see it take affect…

 

Ok….so the grey pic I placed may not look like that in your previewer….it will prob appear a lighter shade of black…..but I just did that in Photoshop to give you some idea on how it works….

The diffuse texture is what goes into the diffuse section in your previewer….

And the Opacity texture goes into the Opacity section…….

Ok..a few things to remember……….the diffuse texture and the Opacity texture….MUST be exactly the same size as each other…..otherwise it will NOT cut out correctly or with sharpness.

You must always use the correct mapping template for the product you are working with…….so for a anyskin muscle top…..derive from a skintight muscle top…….and get the mapping guide……most dev’s who make derivable opacity meshes always provide the template on the catalog pages……..for a full body anyskin….derive from a skintight bodysuit…..for a face tatt….derive from a face product…..and so on……

When you first open the derived product….take note of the texture size they have in there…and make your textures to that same size…..otherwise your tatts may appear not in the place you think they should go…….sometimes the dev’s will specify what size to use.

Opacity works the same for many products…….for furniture…..for some items in rooms…….for clothing also….

Imvu has a slight bug in it though…….have you ever had your clothes or hair dissapear when your in a room?……. That is caused by the two Opacity products conflicting ….most hair is made using Opacity…….and a lot of clothing also…..so when in a room…..where opacity is used…usually ones behind windows……or behind sheer…..one of the products will dissapear…..

Once you have the idea of opacity mapping down…….its then simple to let your creativeness shine.

In the next tutorial…..I will show you how I make a male anyskin muscle top tattoo..

Please drop me a message if you found this tutorial useful…..as feedback is always good to have….tutorials take time to make….and its nice to know people out there are using them…..you can send me a message straight from this site in contacts section…..
