Hard-coded surface levels break the moment you nest a popover inside a dialog. Fluid Functionalism Surfaces fixes this with 8 substrate-aware levels — components read their depth from context and lift relative to it. Light mode, dark mode, any depth. One primitive. Zero props passed between layers. (Open Source)

🎓Learn how to create a powerful Worn Leather smart material in a matter of seconds in my latest video series (AAA) Pro Tips! This smart material can be used on virtually any 3D asset. ____________________________________________________ In this video, the steps are as follows: 1. Create a fill layer with a black mask applied. Inside its mask paint a simple pill shape and use a blur slope filter to introduce some random shapes. Apply a marble veins fill layer on top with its blending mode set to color burn. Apply a warp filter as well to introduce some randomness followed by an anchorpoint. 2. Create another fill layer using the same technique to apply some dirt in the crevices of the wear. 3. Next, Inside the main fill layer apply a tiling raw leather texture to its Color and roughness channel 4. Create an additional fill layer up top and apply a black mask to it.Inside this mask retrieve the anchorpoint information followed by a blur filter with a value of 6. Use a levels to increase the spread of the mask. Apply another marble veins matching the values of the marble veins fill layer that we previously added and set its blending mode to multiply. Lastly retrieve the anchorpoint information from the previous fill layer again but this time set its blending mode to subtract. This fill layers properties should have a dark diffuse color and a matte roughness. 5. Add another fill layer with a bright diffuse and height properties with a black mask applied to it. Inside its mask retrieve the anchorpoint information again followed by a blur slope. Apply the anchorpoint information again but this time set its blending mode to subtract. Now we have a worn leather effect wherever we paint using the paint layer created inside the callout mask! ____________________________________________________ More AAA Game Dev Tips can be found on my YouTube channel here: Stay tuned for more weekly Tips!

🎓 Learn how to create a Cherry Wood Material in a matter of seconds in my latest video series (AAA) Pro Tips! ____________________________________________________ In this video, the steps are as follows: 1. Create a slightly red-colored fill layer with high gloss to act as the woods base material. 2. Add a second fill layer with a black mask, and inside that mask add a stripes greyscale set to planar projection. These stripes will act as the wood rings and should be projected onto your mesh in a natural way. The stripes should also be set to max softness, and followed by a Directional Noise 3 with a blend mode set to Difference. 3. Add a levels to tweak the mask and add an anchor point to the mask as well. 4. Create another fill layer with a dark brown diffuse, and store the information from the anchor point into its mask. Apply a levels to increase its intensity, and then add a fill layer up top with the anchorpoint information applied again, but set its blending mode to Subtract. 5. Create an additional fill layer with a very dark diffuse channel. Add a mask to the fill layer and inside its mask add a fill layer containing the anchorpoint information, from the Wood Rings. This fill layer can now be used to add some dark contrast to the center of the wood rings 6. A warp filter should also be used to apply some subtle imperfections to the wood rings and grain. Now we are left with a very nice result of Cherry wood! ____________________________________________________ More AAA Game Dev Tips can be found on my YouTube channel here: Stay tuned for more weekly Tips.

MIT filmed a mathematician proving the theorem behind every equation Maxwell ever wrote. Most engineers use it daily without understanding why any surface gives the same answer - and the ones who can explain it earn $350K at aerospace firms. Stokes' theorem is the reason Maxwell could write four equations instead of forty. Every result in electromagnetism, fluid mechanics, and differential geometry sits on top of it. Understanding it changes how you see every circulation and flux problem in physics. This is Denis Auroux. MIT, 18.02, Multivariable Calculus, Fall 2007. Lecture 31. It covers Stokes' theorem - the result that unifies line integrals, surface integrals, and curl into one statement. He opens with one confession. Then the statement. The work done by a vector field along any closed curve equals the flux of its curl through any surface bounded by that curve. Not a specific surface. Any surface you want. You pick whichever one makes the calculation easier. Then Green's theorem disappears. The result from the plane that converts line integrals to double integrals turns out to be Stokes' theorem in disguise. Same formula, restricted to a flat surface in the xy-plane. What looked like two separate theorems is one. Then orientation. Walk along the curve with the surface to your left and the normal vector points up. This rule is not chosen for elegance. It is the price of having a consistent coordinate system in three dimensions. Then the proof. Cut your surface into tiny flat tiles. Apply Green's theorem to each one. Sum everything up. All interior boundary edges cancel. Only the outer edge survives. The sum of tiny Green's theorems gives you Stokes' theorem for any surface. Watch the moment he computes the same line integral two ways. First directly - answer is pi. Then through a paraboloid instead of the obvious flat disk. Longer calculation, stranger setup, same answer. The theorem is not an abstraction. You can watch it work. A fluid dynamics engineer I know kept this lecture open during their first week modeling atmospheric circulation. Said it was the first time Stokes felt like a tool rather than a formula to verify on exams. Free on YouTube, MIT OpenCourseWare, 18.02. bookmark this and watch later - after this lecture every circulation, every flux, and every curl you encounter will feel like three views of the same object
