![]() ![]() Hopefully we can get to the bottom of this one. Down in Bermuda is available at: GOG Steam HumbleBundle We get a small commission from any game you buy through these links (except Steam). This info will be handy to pass along to Unity as well to see if they can get to the bottom of it.įor reference this is offending crash log message:ĭ3d11: failed to create buffer (target 0x10 mode 1 size 65576) since compute isn't supported at this feature levelĪlso, I've found two thread discussions on this topic which might shed some more light. The main suggestion I have at this stage is to make sure your GPU driver is up to date.Īnyone experiencing this bug, could you please let me know what OS and OS version, Graphics card model and drvier version you're using (I'm assuming windows because it's a Direct X related crash) so we can start to see if there's a pattern. ![]() We'll file a bug report with Unity, but it seems that this issue has popped up for various games and players since 2017. My guess is that your graphics card doesn't support 'compute shaders', but it shouldn't crash, it should fallback to simpler shader. You can experiment fairly safely with things like rubbing alcohol and mineral oil or lamp oil.I've been looking into this crash and so far it sounds like it's a rare DirectX related driver crash affecting many Unity games. These faults are formed when a crustal block moves up or down with respect. Lava lamps powered by heat are trickier to make and can use more hazardous materials. Anchialine habitats in these locations are found in the form of lava tubes. The water / gas combo is less dense than the oil, so they rise to the top of the flask.Īt the top, the gas bubbles pop and escape into the air, allowing the dense water to sink back to the bottom again. The Alka-seltzer reacts with the water to produce carbon dioxide gas bubbles. Instead of using a light, in our homemade lava lamp, we used Alka-seltzer to assist in moving the molecules of the liquids the lamp. As it gets farther from the light, it cools down, becoming denser again until it sinks then the cycle starts all over. The denser liquid sinks to the bottom, but the lava lamp light heats it up until it expands and becomes less dense, causing it to rise upward. In a real one, however, the densities of the liquids are much closer together than vegetable oil and water. ![]() Real lava lamps use a polar and non-polar liquid just like our homemade one did. This is why oil and water don't mix! What Happened: Oil molecules, however, are non-polar- they don't have a positive or negative charge, so they are not attracted to the water molecules at all. Just like in a magnet, where north poles are attracted to south poles ("opposites attract"), the positive end of the water molecule will connect with the negative end of other molecules. The other end, with the oxygen, is negatively charged. The end of the molecule with the two hydrogen atoms is positively charged. ![]() Water molecules are "polar" because they have a lopsided electrical charge that attracts other atoms. Polarity is the quality of having two oppositely charged poles. Density is affected by temperature-the hotter a liquid is, the less dense it will be. This is because water molecules are packed more tightly a cup of water actually has more mass than a cup of oil.īecause water is more dense than oil, it will sink to the bottom when the two are put in the same container. If you measure an equal volume of oil and water, you'll find that the water is heavier than the same amount of oil. (The scientific equation is density = mass/volume.) Concept 1: Densityĭensity is the measurement of how compact a substance is - how much of it fits in a certain amount of space. A lava lamp works because of two different scientific principles: density, and polarity. ![]()
