Lesson 0
Thank You for the lesson!
I've got the full version of The Ball so I don't know if there are also levels in the demo that contain water surfaces like these. I hope that we will learn how to fix this common issue in UR3 games, too ;)

Lesson 5
As I just had a look at The Sims 4 I've decided to use this game to make some experiments with the shaders. There is a strange "gap" at the edge of the lots. The ground is at correct depth but near the edge of the lot the texture is only rendered for one eye depending on the stereo settings and the distance:
I discovered that this issue appears as soons as You paint a ground texture (soil, cobblestone, etc.) on the lot. Without this painted textures and only the common ground grass texture present everything works fine:
I identified the PS (68D76126) used for some of the lots:

By experimenting with the shader I discovered that commenting out texld r2, r0, s2 removed the painted texture and so the issue with the edges. But it also removed parts of the common ground grass texture on the lot:
I was lucky to find that repacing s2 (samplerPaintTexture) with s13 (samplerTerrainCubeMap) replaced the missing parts of the ground texture. So "texld r2, r0, s13" is a workaround. In additon there are 3 other types of lots that use different PS than PS 68D76126. In this case my trick with samplerTerrainCubeMap didn't work. But I could disable the painted textures by replacing these shaders with the equivalent shaders for the empty lots without painted textures. I only had to adjust the c... and s... values. When I tried to make the disabling of painted ground textures toggleable I discovered that in some cases texld inside if_eq statements cause helixmod to ignore the override. So texld had to be replaced with texldl. I had the same issue with some texldp lines. In this case I had to use registers to keep texldp outsdide if_eq statements: Instead of:
if_eq r30.x, c3.x
texldp r2, r2, s5
else
texldp r1, r1, s5
endif
I used:
if_eq r30.x, c3.x
mov r9, r2
else
mov r9, r1
endif
texldp r9, r9, s5
if_eq r30.x, c3.x
mov r2, r9
else
mov r1, r9
endif
Lesson 6
In lesson 0 I have posted a screenshot with halo issues caused by water surfaces. Now I wanted to see if I already can fix these issues using the prime directive. Finding the relevant PS and VS for the issue was very easy as the texture for the water surface and so the issue disappeared.

// At this point r0 is the output position, correctly

// To create stereo effects, we need to calculate:
// Xnew = Xold + Separation * (W - Convergence)
// Fetch the Separation (r30.x) and Convergence (r30.y)
// using the Helix NVapi trick
texldl r30, c200.z, s0
// (W - Convergence)
add r30.w, r0.w, -r30.y
// multiply that times Separation for:
// Separation * (W - Convergence)
mul r30.z, r30.x, r30.w
// Add that to Xold for the complete:
// Xold + Separation * (W - Convergence)
add r0.x, r0.x, r30.z
mov o3, r0 // move fixed r4 (r0) into o3
// approximately 133 instruction slots used
Using this method I also could fix the halo caused by waterfalls and their fog.
Now the area shown in lesson 0 looks like this:
There are still issues caused by the shaders for the refraction of the water. I hope that these can be fixed, too ;)
Lesson 0.5
On my system The Ball plays the intro video with 1 FPS and crashes when I use AllowNvidiaStereo3d=True. So I couldn't do the quiz and (re)post some experiences I had with game settings and ini files instead: Unfortunately fixes by ini files and graphic settings became less useful in the last years as the PCs became more powerful especially in comparison to XBox 360 and PS3. So most PCs can handle dynamic shadows and simple post effects and there is no more option to turn them off completely. You often only have "low" settings that reduce the shadow's resolution but do not disable it completely. Another reason for very limited in-game settings are ports of console games that only allow You to choose "graphic quality" levels that combine many effects in a single slider. So You often have to disable several effects that work flawless in S3D to remove the one that causes issues. In this case the following trick may work:
Start the game with the highest settings. Then reduce the quality settings until the issue disappears and apply it. Change the settings again to higher quality. IGNORE it when the game tells You to restart the game to apply the higher settings. If You are lucky the effects causing issues still are disabled but other effects without issues are reenabled this way and You get better graphic quality without issues than using the lower settings from the beginning. I still use this trick with Sims 3 which often crashes with helixmod. But of course helixmod is very useful to disable single effects that are bundled with other effects in the general quality slider.
Regarding ini/config files: sometimes You don't have the option to disable effects (setting it to false, off or 0). Then You may try to "break" the effect by using false values at another point. In chrome engine games for example You could not turn off the dynamic shadows but disable them by using ShadowMapSize(1). In some cases it is also useful to flag the ini file as "read only" as Your own settings can be replaced with the default values as soon as You open the option menu in the game (just to change audio settings etc.). Sometimes it may be necessary not to change a value in the config file but also in other files (e.g. for the default settings or backup files from earlier settings). So if a setting in one file doesn't seem to have an effect it can help to search other files that also contain the relevant phrase and change them, too.
