A month later and I finally have a render ! Still plenty of code to migrate, but I'm happy to have the depth prepass and ssao working (now on SDL_GPU) !

Just noticed curved motion blur looks wrong when spinning the camera while looking down. But it sure as hell looks fun/trippy !

Was checking out the latest Anno GDC conference slides and noticed the MSAA mention: only 1.14% of their PC used switched from TAA to MSAA.

Some folks asked to see my motion blur in movement, so here it is, slowed down 3 times (90fps to 30.fps). You can see a bit the curving effect. :D

Small update: now my motion blur can be curved. 👀 Same as before, but now I shift the sample position along a quadratic bezier curve, based on 4 states of the camera.

I generate mips and use textureGrad with anisotropy to make it a non-uniform blur, needing only 7 taps per pixel. Final result is really good, and cost 0.4ms (downsample, mip, effect, blit back up).

Now 100% sold on the upscale pass for it yet, but current results are relatively good still. :) (I support spotlights and my local directional lights only for now.)

By hey ! Now I have a particle entity in my level ! :D

To illustrate a bit, In the worst-case scenario this is how it looks like:

I fell for this new French edition of Jules Vernes 20,000 leagues under the sea. It's incredible, the layout and font choices are soooo good !

The result is nice to the ears, and also less of a pain to press !

I was busy this morning : I changed my brown switches into red one ! They were annoying to remove, but it was worth it.

Took a few tries, but I got the old ATI Toyshop demo running on Linux (with Proton 7). I found some old tech demos to download from here: soggi.org/video-cards/...

That demo level is starting to shape up as I'm now making more and more textures for it. Here are a few bonus screenshots:

Past few days have been focused on building a basic particle system, mostly to add smoke in a few places of the demo level to add some life. I got a simple vertex+frag shader working, driven by the particle logic stored in a texture. I'm already liking the early results. :)

C'est aussi à cette période que j'ai découvert ! D'ailleurs je suis tombée sur ça hier :

Ça marche mieux si on prend le titre original :

Froyok (Léna Piquet) @froyok.fr · 25/05/2025

I think it's a good opportunity to focus on building a demo level and some assets to showcase the engine features. So I started working on a little level, playing with lights and building materials. :D

Froyok (Léna Piquet) @froyok.fr · 25/05/2025

I added some tooltip when hovering assets in the window, but most importantly I started adding support to drag and dropping. First test was with meshes, to be able to drop them into the scene:

Froyok (Léna Piquet) @froyok.fr · 25/05/2025

Then I did a few other style hack to make the tree view nicer to look at, and also started adding icons based on the file type.

Froyok (Léna Piquet) @froyok.fr · 25/05/2025

I moved onto another big task, which took less time than I expected : I finally implemented an asset browser in-engine, to be able to navigate through my project files. At first I spent some time fiddling with ImGui to add a custom split separator that is resizeable.

120

Froyok (Léna Piquet) @froyok.fr · 25/05/2025

Another little feature I finally added was a color picker. I wanted to be able to edit more stuff directly in-engine, so I finally implemented the color widgets for lights. It was easy enough because most of the code was from another project of mine. So "yeay" for copy pasting ! :)

Screenshot of my game engine showing an orange colored button at the top and a floating window below it. The window contains a hue gradient slider and a orange to white/black area below it.
The at the bottom are available several text field with RGB, HSV and Hexadecimal color controls.

Froyok (Léna Piquet) @froyok.fr · 25/05/2025

Then I added a prototype for a new entity type : the rotator ! The goal is to have this entity control another one (here a mesh) to update its rotation. The moody light + fan was born ! :D

Froyok (Léna Piquet) @froyok.fr · 25/05/2025

Now that I was able to get information on the fly, it was easy to expand it to the selection overlay system and draw an outline when hovering object. That makes selection much easier: less mistakes !

120

Froyok (Léna Piquet) @froyok.fr · 25/05/2025

Finding stuff can be hard sometimes, so I started adding more debug information. I added a little tooltip when I hover objects in the scene to get some quick info for example.

Froyok (Léna Piquet) @froyok.fr · 25/05/2025

Been a while, so where are we with things in Ombre ? I continued working on the manipulator a bit to handle scale transformation. I stopped there because I didn't want to think about rotation stuff yet. 😅 Also adjusted its style, wanted to make cooler.

Froyok (Léna Piquet) @froyok.fr · 22/05/2025

Might have been true in the past, but I don't think that's the case anymore. I personally run multiple games or software at the same time, for example:

Updated Mesa and that fixed all my issues. Now my enjoying a lot the game. Also crying a lot. Please enjoy this meme I made: (Tagged graphic to "spoiler" it.)

An image composed a two images top / bottom. Top image is a walking cane. Bottom image is a single frame of a gif from TV show The Punisher with the character saying "no, no, no, no, wait, wait, wait ,wait".

Froyok (Léna Piquet) @froyok.fr · 25/04/2025

The runs game pretty well so far via Proton. Only issue I have is mostly during some cinematics where meshes tend to suddenly disappear, creating very bright flashes because of the background color/bloom. I guess I have another reason to update Mesa.

Froyok (Léna Piquet) @froyok.fr · 24/04/2025

Just for that it is GOTY for me 😆

Haven't played the first game, but seeing a fullbody awarness system in this one, especially for swimming, is actually quite cool. I wish more game would have that.

Manipulator is finally working, I can now move stuff around easily in my scenes. :) I also refined a bit the color/transparency of the manipulator.

130

Froyok (Léna Piquet) @froyok.fr · 21/04/2025

Started adding a state machine in the gizmo code, and hooked some events. So now I can select objects around in the scene and it shows the gizmo on it. Also started animating it, because it's fun. :)

Froyok (Léna Piquet) @froyok.fr · 20/04/2025

And then yesterday night I found out that blue lights were behaving weirdly. After some back and forth I isolated the issue not with the tone curve but actually with my color grading LUT.

Froyok (Léna Piquet) @froyok.fr · 20/04/2025

Hooking collisions after that was easy, because I could use SDF functions on the CPU too to do ray intersections. I use a capsule in this case to make the area a bit bigger.

100

Froyok (Léna Piquet) @froyok.fr · 20/04/2025

A few lines of code later... gizmo was alive ! :D

Froyok (Léna Piquet) @froyok.fr · 20/04/2025

So the first try of making an SDF got borked a bit, but I got nice glicthes out of it once again ! 😆

Screenshot of my game engine showing a weird circular noise.

Froyok (Léna Piquet) @froyok.fr · 20/04/2025

I quickly hit a snag however: sorting issues ! Without depth writing, you cannot properly draw that object, especially since it's a single mesh. However because it's gizmo I didn't want to overwrite the scene depth buffer.

Sorting artifacts of the mesh faces related to depth writing being disabled.

Froyok (Léna Piquet) @froyok.fr · 20/04/2025

So I put that stuff on the back for the moment. I needed a creative break. So I started working on finally implementing a translation manipulator in my editor ! It started with drawing a basic axis mesh at first:

Froyok (Léna Piquet) @froyok.fr · 20/04/2025

I went back to do more Steam Audio after that. This time to plug in the transmission property, which allows sound to go through objects (instead of just being fully occluded).

100

Froyok (Léna Piquet) @froyok.fr · 20/04/2025

I got some "fun" glitches out of it at least. First time it crashes the system, the other times it was able to recover fortunately. (Turns out I writing data into an SSBO but out of bounds).

Screenshot of my game engine with a scene filed with simple cubes and wall. Over the image appears random black squares, typical of GPU artifacts.

Froyok (Léna Piquet) @froyok.fr · 06/04/2025

End result is that I now have occlusion working on my audio sources ! It gets evaluated with several samples so that sounds fade in/out nicely.

Froyok (Léna Piquet) @froyok.fr · 11/03/2025

Some progress on Steam Audio integration: I have now attenuation, air absorption and binaural effect working. Results are starting to get pretty cool ! :) (Sound ON for the demo !)
