Anim To Sprite "Wake-up Sprite Option"
Summary
Intersections between 3D backgrounds and camera-facing sprites are often problematic, especially in Top-View games.
The Wake-up option eliminates this problem to some extent, but should be implemented with caution because it does not work well from a near-vertical perspective and other side effects are to be expected.
How to setup
When using material instances based on embedded materials (M_AnimSprite/M_AnimSprite_Toon), check "bWakeSprite" to enable this option.
"WakeRate" determines the strength of its effect.
If you use your original material, just immitate M_AnimSprite.
MF_WakeSprite does the calculation.
Then check "Use Subdivided Mesh" in the details of AnimSpriteRender component.
Technical Explanation
This section describes the actual effect of this option.
This may help in analyzing the side effects that would occur.
Wake Sprite option offsets the vertices toward the camera so that the mesh stands vertically.
This requires a subdivided mesh to deter image distortion.
A2S provides a quad mesh subdivided into 8x8 rectangles.
