Tutorial (Part II)


Prior to Cubism 2.1, each eye area requires covering pieces "Upper Eye Cover" and "Lower Eye Cover" in order. Including the lips area, 6 pieces of "parts" drawing object designated to cover up other parts of lower drawing order.

Further more, if the model has shadow of the front bangs casting over the eye area, or has a block or gradient of shade on the face, the cover pieces would become very difficult to handle, which may fail to retain the quality of the original artwork.

Cubism 2.1 introduces the new function "Clipping Mask" to solve problems such as the "Eye White" and "Eyeball" breaching the eye's border ("Eyelash") . Therefore, there is no longer the need for having cover pieces as mentioned above. You can have a dynamic control over the visible area of any drawing object. I am happy about the efficiency improvement from this update.

※ However, at the time when this tutorial was made, the "Clipping Mask" function might not be compatible  with some runtime environment. Applications such as games may not porperly display the Live2D model with clipping masks. 

As shown in the image above, the masking function is to apply an mask image onto an original image, allowing the original to keep the texture and inherit the visibility (shape) of the mask.
In other words, the action does not "transform" or "edit" the original image. It is simply hiding the area beyond the mask's boundary.

Change the setting in Cubism Modeler in the following way.

Start wit the "Eye White". 
First, select the "Eye White" drawing object by clicking it on the canvas.
In the "Edit" palette, find the field "ID" and copy or remember the value.

Then, select the "Eyeball" part.
In the field "Clip ID", enter the ID of the Eye White that you've just seen it.
Hit the Enter key, and then test the result by dragging around the "Eyeball' with your mouse.
The "Eyeball" should no longer breach beyond the "Eye White's border.

Let's look at another example.

On the top "Eyelash", there is a small dot of highlight. 
Same here, apply the same method; clip the highlight onto the "Eyelash" and the dot will never float out of he eyelash.

You can also use the "Mouth" part as your teeth's mask. 

That is all about the new Clipping Mask function.

Hope you find this tutorial useful.
