  • [ ] breakdown into five tasks (What player does in your game), what actions the player uses to fulfill this task, be as specific as you can, add GIFs

steam page

steam page with trailer 90-180 seconds long (starting with gameplay immediately, end with call to action (wishlist now), gamespress.com press release, show UI (make outside cockpit UI?), easy to understand shots with player interaction 3-5 seconds each, show variety in biomes, (1920x1080, 5000 kbps, 30 fps, mp4)), capsule art (recognisable professional designed thumbnail), first 4 screenshots important - bright ones and dark ones (at least 3 different environments), good short description (engaging start, mention core hooks, enumerate basic gameplay verbs, by wedesoft (social proof)), add steam page url to long description, add animated GIFs, section banners, main content column images/videos now with 780px width

missions and high scores

[#C] graphics improvements

general quality

  • Note taken on [2025-08-14 Do 12:33]
  • [ ] HDR bloom (separable convolution), Add blurred overflow
  • [ ] multisampling
  • [ ] adapt shadow map size to object distance
  • [ ] integration test powder function
  • [ ] low FPS at 100km height was reported
  • [ ] cloud shadow flickering at large distance?

peek faster than last on vectors

use :let, :while, :when in for loops

use icosahedron for mapping 2D micro textures (better grass)

fix problem with resolution of neighbouring tiles in planetary cubemap

problem with neighbouring resolution levels being to different (maybe use more than two possibilities for edge tessellation?)

improve rendering of sun (see s2016-pbs-frostbite-sky-clouds-new.pdf)

how to render water, waves, waves

increase ambient light (surface radiance)

arycama: limit darkness of cloud shadow (exponential approaching a base level)

add earth light

add moon light

stars, volumetric clouds

uniform random offsets for Worley noises to generate different cloud cover for each game

point sprites for stars, atmospheric flicker using sprite arrays

Skydome: counter-clockwise front face (GL11/glFrontFace GL11/GL\_CCW) (configuration object)

Skydome scaled to ZFAR * 0.5

no skydome and just stars as pixels?

create windows using blending (reflections?)

introduce variation to cloud height
