My personal project mainly work in this week is texturing for plant in substance, and writing dynamic material shader in unreal.
Texturing in Substance painter
Writing material in Unreal
In this process, we need to control the underwater movement of plants through the SimpleGrassWind node. But only through this node to control plant movement, it will cause the roots of the plant to also move. This is not what we want.
For this we need a color gradient to affect the movement of plant roots. The value near the root is 0.
The above GIF is the effect display of plant movement.
