Since the grid of CLIP STUDIO PAINT rotates with the canvas,
I use software called "Doko Demo Grid" when drawing with a tilted composition.
When flipping left and right to check the drawing collapse,
It is useful to be able to match the position of the standard,
(The image below is flipped horizontally based on the red line in the center)
Lines are opaque and you can't change their thickness, so it can be difficult to see.

The grid image is displayed with software called "Transparent paper display tool".
It seemed that it could be displayed as translucent, so I tried it,
In a multi-monitor environment, it was only available on the main monitor.
(Because it is difficult to set the liquid tab as the main monitor)

If you know any good software, please let me know 😋
