Anime FX - Foundations is now public. Before moving into full production shots, this module focuses on how stylized FX are approached. Cel shading, depth, Houdini & Nuke workflows, and key stylized FX fundamentals. This way of thinking carries through the entire material.

As a graphics engine coder I think when you look at a flickering bug like this one in the video below it’s not immediately obvious what is going on. The key here is observation - to study this flickering/bugged render carefully - what do we see? Firstly for me it was very obvious that nearly all of the scene shadows were flashing on and off - but (but!) there was a secondary issue where some buildings and parts of the sky were also flashing purple. Hmmmm. Interesting. I initially thought then this might be two separate bugs - but because the sky purple element could only based on full screen post fx and not 3D rendering I looked at this first with a few GPU captures to step through all our post processing to find the rendering stage which made these pixels turn purple: When I did this I found the colour 3D texture LUT grading that makes our different biomes have unique colour palettes was going very wrong - colours near 0 or 1 were wrapping and making the purple elements that we see in the said sky and base parts. The only way this could happen was if the texture was corrupt (which it was not) or if the 3D texture sampling was wrapping and not clamped as intended. That was the Eureka moment - because if the post fx had the wrong texture sampler then the disappearing shadows which also require an exact texture sampler for comparing depth might be also wrong because of the same kind of texture sampling issue! So with this idea that the engine was using the wrong texture samplers, but only in very high draw call scenes like the big base here I the looked at some engine limits and found the bug very quickly - a circular dx12 descriptor buffer for samplers running out over multiple frames, reusing the wrong data for new scenes inflight. Hence the flickering, as the GPU randomly got wrong samplers for some post textures or shadow depth. Easy to fix with triple limits for future expansion and also adding an assert/debug spam in case this limit is ever reached again - QA testers would see this message and report if they ever saw a flicker with this style of bug. My bug and my bad from 2017 porting NMS to DX12 without foreseeing how massively complex bases and our game would grow.

🚨 WARNING: SOMETHING VERY UNUSUAL IS HAPPENING RIGHT NOW $1.4 TRILLION just vanished from China’s balance sheet. They’re funneling every dollar into Gold. But this isn’t just about China anymore. THIS IS GLOBAL. If you're holding any assets right now, you MUST know this: The U.S.-Iran war is escalating. The ceasefire talks just collapsed. There is no pause. NO RESET. Only escalation. And markets are starting to feel it. This is how systemic shifts begin. Quiet at first. Then all at once. Gold is pumping again and this isn’t just “hype.” It’s a repricing of TRUST. A repricing of RISK. A repricing of WAR. This isn’t “diversification.” THIS IS STRATEGIC. When geopolitical conflict collides with monetary instability, capital runs to one place. Gold. THE ultimate safe haven. Let’s break it down simply. Treasuries sit at the foundation of the dollar system. So when a giant like China keeps pulling back, the system must rebalance. Now add war to the equation. Now add broken diplomacy. Now add rising global uncertainty. And suddenly, everything starts to move faster. Gold doesn’t move like this when things are stable. Gold moves first when TRUST starts cracking. China isn’t speaking. They’re signaling through capital flows. They’re done with paper promises. And now, the world is being forced to listen. When the largest players shift like this, others follow. Markets don’t react early. They react AFTER the shift is obvious. Not through headlines. Through FLOWS. Through PANIC. Through WAR. I’ve spent 10 years studying markets and called nearly every major top - including the October BTC ATH. Follow and turn on notifications. I’ll post the warning BEFORE it becomes public news.
