Dropbox has a "fun" bug since a few weeks on my machine.

Each time I wake it up from sleep, and a file is modified, Dropbox app becomes crazy and eat up all my ram.

Take 5 minutes for the system to notice and kill it (or maybe it crashes because it can't allocate further).

I doubt I will bother report the issue, given how unhelpful their support is on their forums.

Currently writing a Python script to auto-kill it before it slows down the machine and relaunch it.

I guess I could also put it into the sleep schedule. 🤔

I wonder if anybody tried to use FXAA before doing display mapping BUT by still applying and reverting a curve ? 🤔

Aka:
1 - Switch from HDR to SDR
2 - Apply FXAA
3 - Switch back from SDR to HDR
4 - Apply regular post-process stuff

Finally !

Weeks (if not even months) or rework and I can finally render cubemaps.

Pretty happy about it, especially since the cubemap generation side of things took less than a day to write. My refactor worked out really well. :)

@froyok Just as another reference point, we've written an accurate analytic fit for the integrated FG term in MaterialX, allowing you to render energy-compensated GGX reflections without texture lookups.

Here's the analytic fit for the integrated FG term:

And here's the method that leverages integrated FG to compute energy compensation for multi-scattered GGX reflections:
