    ok I fixed the arrow keys movement, but is the yaw/pitch movement strange or it's just me

    I feel like the cube is rotating
  • t
    for some reason
  • t
    I fixed some lag too, I forgot to instantiate the cube only in init
  • t
    I think it's clearer now

  • h
    Cool so was it the cube rotating ?
  • t
    actually I was technically trying to fix a non-existent bug, so the cube wasn't really rotating, I just tried rendering the same cubes as in the other screenshot to test something and it behaves as expected
  • t
    so it was just an illusion
  • t
    😐
  • h
    Ah.... ok. Cool, so on to lighting...
  • t
    finished some

  • h
    nice ! I'm wondering what the slightly darker patches are on the faces of the cube - I'm guessing just rendering artifacts ?
  • h
    looks like it's reflecting something which in that demo it can't be
  • t
    oh lol I see what you mean, no that doesn't appear here
  • h
    Qso it's just in the capture. Ok. Compression artifact then maybe
  • t
    yeah
  • t
    also btw
  • t
    is it normal to see the shiny spot (the specular lightning thing) when I get closer to the cube
  • t
    I mean it doesn't show up when im a little far
  • t
    same distance as in the gif
  • t
    but when getting very close I see it
  • t
    I think you can see it here

    I haven't run my code in a while but what I recall is that the specular hotspot is sensitive to view angle and to the exponent you use. I know when I go onto the later models cases you would only see if when the light source, the model and the viewer (camera) were at the correct angles to each other - which makes sense.
  • h
    Also the intensity of the spot will make it smaller - lower intensity it will be more diffuse
  • h
    all the lighting parameters is a major reason I have a UI in my - so you can tweak them realtime and see what they do
  • t
    ahh I see
  • h
    In the image above - I think you see a fairly diffuse hotspot in the top towards the right corner - but it feels like that hotspot is not reflecting directly into the camera or it's intentionally diffuse
  • h
    if you rotate the cube face a little that might help - also the reason it helps to be able to rotate the model
  • t
    I think it's a rendering thing too
