How to make an X-Ray effect (Gentleman-Frame sample scene) (Patreon)

Someone asked about how to make an x-ray of clothes. It is out of the scope of VNGE or MMDD, but this trick is very useful in Hentai MMD, as known as 紳士枠 (Gentleman Frame). By adjust the Render Queue of materials, we can make similar effect in studio.

This sample may not 100% work, maybe depends on the something I don't know. I am not familiar with this render things actually, so don't ask me about why this happens.

What you need is Material Editor plugin, which is very famous and I think everyone already installed it.

The x-ray effect need a mask to cut off clothes, the simplest one the a image-board with a transparent image loaded. But in my studio, a completely transparent image doesn't work, so what I used is a image which is 99% transparent. I attached these two image, alpha0.png is completely transparent and alpha1.png is 99% transparent. You can try by yourself.

Of course, nothing will happend if only load a transparent image. You need to adjust the Render Queue in Material Editor too! I uploaded an screenshot to show where you can find the setting to adjust.

By default chara's body skin's queue is 2410, the clothes is 2450 and image-board is 4510. To make x-ray, adjust image-board's queue to 2500 and then clothes's queue to 2600! Now the part of clothes covered by image-board is see through! For detail check the screenshot above and the sample scene in attachment.

Tips: 

• When you see through the clothes, make sure to turn off its Cast Shadow setting. Or its shadow still there.
• Sometimes you need to adjust clothes's "damaged rate" if it cuts off a part of body. (sorry I don't know how to say it clearly...)

Hope this sample can help you.
