Thank you for the nice documentation! I wish I had found this earlier, but since I didn't, I made my own little investigation a while ago and thought it might be helpful to share it here, as an addition: As you can see, not only cause the channels different types of shine, they also act in a combinatorial manner (e.g. green alone is strong, but green&red are super-strong). Blue seems to tone down the effect. Also: the alpha channel is absolutely required for all types of shine

I was a little confused (okay, a lot confused) about all the talk about colors, transparency, greyscale, etc. It all seemed contradictory to me and I wasn't sure how to apply what method where and how and to what degree. Then, I realized, the different methods depend on whether you are using a .png or a .dds image, and realizing that was a lightbulb moment for me. Using the corset as an example, in a .png image you will find that the red, blue, and green channels in the main image all utilize greyscale colors and levels of opacity to create various effects. The .png mask image, on the other hand, uses a white to black color scale that seems to control how transparent the final object will be; in the case of the corset, the lace is partially transparent in the game so the lace on the mask is grey (darker grey is more transparent; lighter grey is less transparent), while the rest of the garment is opaque in the game so the rest of the garment on the mask is white. In both .png images, you will not have an alpha channel at all. Things are different if the image is a .dds. For starters, the main image will have an alpha channel, though I'm not sure what the alpha channel in the main .dds image does, to be honest. The red, green, and blue channels are all varying levels of greyscale. The .dds mask does not have an alpha and seems to work the same way a .png mask works--controls the same thing. Note that all the above information is pertinent to CAS items. So, to summarize, when you see talk about changing the level of opacity in a specular, this means that a .png image is being discussed and not a .dds image. I'll bullet-point it all. PNG Image:- Main image has a red, green, and blue channel--no alpha channel
- Main image uses grey-scale in each channel (R, G, B, and alpha)
- Main image opacity level works the same way the alpha channel in the main image does if you are using a .dds file--fully opaque has the strongest effect, while lowering the opacity decreases the strength of the effect
- Mask image has a red, green, and blue channel--no alpha channel. None is needed
- Mask image uses white to black color scale
- Mask image controls levels of transparency of final product--from fully opaque to fully transparent. Black creates invisibility, while white creates a fully opaque effect in the finished product. Different levels of grey produce different levels of transparency in the finished product
DDS Image:- Main image has a red, green, and blue channel, AND an alpha channel
- Main image uses grey-scale in each channel (R, G, B, and alpha)
- Main image does NOT use any opacity for effects--uses an alpha channel in the main image, instead
- Main image alpha channel controls strength of effects--white has the strongest effect, while darker grey decreases the strength of the effect
- Mask image has a red, green, and blue channel--no alpha channel. None is needed
- Mask image uses white to black color scale
- Mask image controls levels of transparency of final product--from fully opaque to fully transparent. Black creates invisibility, while white creates a fully opaque effect in the finished product. Different levels of grey produce different levels of transparency in the finished product
I hope this helps clarify things. I wrote the above out to help straighten things out in my head since the info was all jumbled. orangemittens , did I get this right? If any of this is wrong, please let me know.
