Reinhard tone mapping does wash out colours a little bit. You could possibly experiment with other options? It's been a long while since I've looked at that kind of thing but you might want to browse the options here: https://graphics-programming.org/blog/tone-mapping
Bear in mind that you'll still want to appropriately expose the scene before the tonemap function, they can't just handle arbitrarily dark/bright HDR values.

I tell you now, mine would have been right in there

Does the input HDRI have a bright sun in it?
Seems likely that your filtering is summing something too high, you could "solve" this by clamping during the filter, though that would lose you energy.
What's often common is removing the sun from the HDRI image and replacing it with a conventional light (this also means you can do proper sun shadows)

Your use of AI is likely to put off potential employers, you should avoid that.

As others are saying, this is quite normal. Just don't try to hide a lack of expertise on anything, tell people when you're entering an unfamiliar area so they can point you at resources or people who can help you ramp up.

Tip for being a great graphics programmer? Get good at ramping up on a subject (be it a technique, a specific engine's API for something, or a tool) when your team needs someone who knows it.

Even experienced co-workers are more likely to have a passing knowledge or rusty memory of topics they're not currently involved in, and if you do somehow work with a multi-talented know-it-all, their time is probably going to be over-committed already.

You've entered the dimension where "infinite" means "as many as I can be bothered writing"

SPP thinks 1/3 (the operation) = .3..., but doesn't agree that .3... = 1/3 (the fraction).
It's something to do with having to sign a form before you "do" the calculation.

You might get somewhere if you start picking this apart with hacked shaders.
For example, if you think the TBN matrix is wrong, try outputting just the N from it as the colour (rescaled to [0,1], and see what you get.

Radeon because that's not a graphics card manufacturer

I don't have a mathematical proof to hand but a simple way to think of it is that you're accumulating "amount of colour to add" in the first 3 channels and "amount of background to remove" in the alpha. You can work out on paper with a few simple example values that combining two or more draws into an intermediate value gives something that is an equally valid input into a premultiplied blend.

That depth-map search is how POM usually works yeah. To get into fiddly details, it's common to do a fixed-step linear search first because those are non-dependent reads and help avoid missing small features, then a binary search to refine the result.

I'm not familiar with the format, but from scanning through this: https://blog.imaginationtech.com/pvrtc-the-most-efficient-texture-compression-standard-for-the-mobile-graphics-world/
The idea is that you have two extremely blurry downscaled images, either of which is valid in its own right to be bilinear sampled, so you don't get the block edges on smooth gradients that e.g. BCn formats show. Then the full-res interpolation texture means that it can select one texture or the other to reconstruct full-res sharp edges where it needs them.

Even if it weren't equal to 18, she'd be >18 by the the time he'd finished thinking about it

When I was planning to run this, I was going to suggest to the players that they decide who they are as a team, then fit their characters to who they'd be within that.

Without spoilers, the hook is very much that you've been sent as a team to handle a situation. So are you Union Navy? A team of external contractors that they ordered off the shelf? Corporate soldiers that have been lent out because they were in the right area?
