Hello everyone ! It's been a long time since I have posted on this forum, but i wanted to share my current project, and get some feedback and critic as I'm building it. Beware that I like GIF so this thread will be quite gif heavy :smiley:

The goal of this project is to  make an interactive 3d experience, that will be played on PC, and if I can achieve good performance, playable in browser. The concept is pretty simple : You will be able to spawn some kind of energy (represented by particles) and follow their movement to find hidden objects in the scene.


Here is a quick and dirty concept I did for this environment, as you can see this will be in a form of a small city diorama : 


My main references is the city of Dinan in france, I really like the blend of an old medieval city, with a lot of "modern" stuff on top ( wires, camera, electric boxes,...)

Here you can see a bunch of references I gathered :




Unfortunately I'm starting this thread while the project as already started, but I still have some picture to post. (you can see everything from the beginning on a twitter thread I made)


The first blockout of the scene, with a quick lighting in Unity. 


from here I started modeling some of the elements and props.


And finally the last upate, with a bit more update on the props, trying to find some lighting mood ( in marmoset for quicker iteration).


Please note this project is not only about creating a 3d environment, there is a big part i'm working with Houdini : I'm using houdini to generate data to drive some particles around the surface of the environment. 



(posting a twitter post here, because I don't have the original gif anymore :s )



the movement of the particle is driven by flowmap made from Houdini data using Space colonization. Here is how the data looks in houdini before being baked onto a flowmap (mapped on the lightmap uv of the environment) 

I hope you guys will find seeing the process of this project interesting,. If you want to see more detail about certain , I'll try to make more screenshot and breakdown
