I figure I could do an #introductions too.

I'm Froyok / Fabrice Piquet, and I have been working on Substance Painter for almost 8 years, initially at Allegorithmic and now at Adobe.

In my spare time I play with the Unreal Engine, experiment with shaders and sometimes draw stuff. So it's mostly tech art oriented. :)

From time to time, I write articles on my website, often about Unreal: https://www.froyok.fr/articles.html

Got the base collisions in.
I ended-up building them in Tiled too by hand.
I suppose this could become be tedious in the long run, but I like the idea of freedom from the tileset itself that it gives.
Plus is as easy to parse as the tilesets themselves when exporting to the game.

While googling about how to do lighting and shadows in a 2D game, I stumbled upon this great blog post from the devs of "Graveyard Keeper", I highly recommend the reading: https://www.gamedeveloper.com/programming/graveyard-keeper-how-the-graphics-effects-are-made

Okay, added some noise and little waves, I'm really liking that result !

A "few" tweaks later, I have animated water ! :D

#gamedev

Took a few tries, but I got the Jump Flood working an now have a Distance Field texture working ! :D
Just need to cleanup the pipeline now and integrate it in-game ! \0/

Before moving on to collisions (which I have prepped the data for it already, now I need to translate it into the game) I want to play a bit with water surfaces.

Right now I built a new set of tiles with transparency. The goal is to render the map as a black and white mask and then generated a distance field from the hole.
From there I should be able to generated dynamic shorelines. :)

It's starting to come together nicely. Loving it ! 🥰

The advantage of using Substance Designer for building textures: using the height-map as a blending mask to make terrain/tiles transition for free.

Each time I want to build a new transition I just need to plug two materials together in a filter. :D

Haha, that made my day ! 😀

For example I store in Red and Green the center of each tile so that I can scale it up/down to hide the tiles seam because of the texture sampling.
Texture are simple enough that I don't need padding in them at all.

My python toolset parse the Tiled json file, build the mesh in a lua file, which I simply load at startup. And voilà !
UVs are directly set properly and I can use vertex color to get additional data.

Technically I ditched the idea of using a screenspace shader pass and went back to using dedicated polygons.
The nuance is that I precompute the mesh for each map, instead of using a generic mesh.

Finally made it work !
I'm walking on my map, yeay !

I made only the base layer work for now, next are the other layers. Then it will be collisions.
