Specular Map on a Transparent/Simglass shader Cas Item

Hi odeodeodeodeode ! Firstly, and un-related, Thank You for the screenshot of Studio on a Mac! I haven't really seen much of it in-use on a Mac, and it helps me to visualize that a Mac user is looking at while helping them!

About your question: Most definitely Yes, SimGlass *does* indeed use a Specular Map - look at any pair of glasses and you will see. That said, I had an immediate thought of *exactly* what you might want to look at to get an idea of what to create: the "Rhinestone Sparkle" eyeshadow from SP01. Look at its specular (and mask - VERY IMPORTANT to include as well!) and you will see how a 'sparkle' specular is made. Having said that, though, I realized from re-looking over your post that you are using a single, simple mesh and letting the texture's alpha create the 'shape' of a pair of wings. Each mesh for a CAS item can have only one specular, so you will be faced with the decision of how to approach your sparkles - do you make multiple clones and custom-tailor the sparkles for each, or do you think of a general 'average' between them to come up with only one specular mapping?

Crispy clean sparkles will look Great on your lovely wings! Cheers!

We have a good tutorial, even 2 about specular maps. Please read them here, and here.

I need to correct minimoster. Actually there can be multiple specular files in one .package. They can be managed on a Warehouse tab. I used 2 maps in the past in some of my items and it worked perfectly. One map can be imported on Studio tab, other specular maps should be imported on a Warehouse tab. To make it work user needs to either create new resource, change instance number with another one generated in Hash generator, and write an information about it in a corresponding CAS part resource. CAS part resource carries all information about what swatch goes with what thumbnail, what spec goes with that swatch, what tags that swatch has, will this swatch appear with certain accessories or not. The only resource that is not tied up to CAS Part is normal map. Information about it is in geometry files.

1. Generate new number in Hash generator in Tools -> Hash Generator. I usually enter name of the item and color of the swatch, Studio will generate the numbers, copy FNV64 number.



2. Add new resource either by duplicating existing RLES resource (specular) or adding it, changing Type to RLES and pasting previously generated FNV64 number into instance field. Notice 2 RLES resources on this screenshots, these are my 2 custom specular files. You can add a custom specular file for each CAS part.


3. Find CAS Part that you made this additional specular resource for. Usually I just pick a very bright color with color picker on a Studio Tab. This way it is easy to spot needed CAS Part in a Warehouse.
In a search field type "specular" and in the "instance" field enter instance number of newly created specular resource.
