Greetings @DaWeiLiang; thank you for posting your project, “Fantasy Gardens,” and welcome to the Unreal Forums!
I had the chance to look at the linked game-play you provided, and I am beyond impressed! Everything about this game is unique, and the details (sunlight control, camera focus, and blur) are chef’s kiss! How long did it take to create “Fantasy Gardens?” Are you looking to develop similar projects in the future? 
I really have to stop looking at other people work. I see this and then I look at my work and I instantly think “wow, my game really looks like ■■■■compared to this”.
This looks wonderful. How the hell did you make the flowers grow like that!? There really is some talented people around here…
Thank you!
It took me about six months to create the game。
Thank you ! I use Niagara particle to simulate plants grow.The trunk and stem are made of cylinders.Flowers are staticMeshs with vertex animation textures.
No problem at all, and it only took you six months to create? Wow, that’s even more impressive! Congrats on a job well done, and thanks again for sharing your work.
