shapez 2 Fluid & Paint Guide
Fluid dynamics in shapez 2 are more complex than they first appear. Pipes have throughput limits, valves are not optional, and paint mixing creates bottlenecks that can stall your entire factory if you do not plan for them. This guide explains exactly how fluid moves through pipes, why valves are essential, how to optimize paint mixing ratios, and which colors are the most expensive to produce. Master these mechanics and your painting throughput will never be the bottleneck again.
Paint Types — Mixing Recipes and Throughput
shapez 2 has 7 paintable colors: Red, Green, and Blue are primaries that require only an extractor. Cyan, Magenta, and Yellow are secondaries that require a Mixer. White is a tertiary that requires a 3-input Mixer. Crystal is a special fluid produced by the Crystalizer, not the Mixer. Each color has a different throughput characteristic that affects how many Painters it can supply.
| Color | Source | Mixing Recipe | Mixer Tier | Paint/sec | Best Use |
|---|---|---|---|---|---|
| Red | Red Fluid Extractor | Primary — no mixing required | N/A | 1.0 | Most common Hub goal color. Always extract directly. |
| Green | Green Fluid Extractor | Primary — no mixing required | N/A | 1.0 | Second most common. Keep a dedicated extractor. |
| Blue | Blue Fluid Extractor | Primary — no mixing required | N/A | 1.0 | Third primary. All three primaries should have dedicated lines. |
| Cyan | Mixer (Blue + Green) | 1 Blue + 1 Green → 1 Cyan | Tier 1 Secondary | 0.5 | Centralized mixer feeding 2 Painters max. |
| Magenta | Mixer (Red + Blue) | 1 Red + 1 Blue → 1 Magenta | Tier 1 Secondary | 0.5 | Mix in bulk and buffer in fluid tank. |
| Yellow | Mixer (Red + Green) | 1 Red + 1 Green → 1 Yellow | Tier 1 Secondary | 0.5 | High demand in late-game goals. Stockpile buffer. |
| White | Mixer (Red + Green + Blue) | 1 Red + 1 Green + 1 Blue → 1 White | Tier 2 Tertiary | 0.33 | Lowest throughput. Dedicate 2 Mixers to meet demand. |
Pipe Throughput Mechanics
A fluid pipe in shapez 2 can theoretically carry 1.0 fluid units per second. In practice, a pipe with no valves only delivers about 0.3 to 0.5 fluid per second. The exact rate depends on pipe length: longer pipes have higher resistance and lower effective throughput. This is why your Painters appear to starve even when they are connected to a running Mixer or Extractor.
Valves solve this problem. Each valve forces fluid through at an accelerated rate. Community testing has confirmed that 2 valves per pipe run is the minimum for full throughput, and that valves should be spaced evenly along the pipe rather than clustered at one end. A pipe with 3 evenly spaced valves achieves full 1.0 units per second throughput even at lengths up to 30 tiles.
Fluid Launchers are an alternative to pipes for long-distance fluid transport. A Launcher can send fluid to a remote painter instantly regardless of distance, with no throughput penalty. Use Launchers when your paint production is far from your painting area — they eliminate the entire valve-optimization problem.
| Pipe Configuration | Fluid/sec | Painter Feeding | Fix |
|---|---|---|---|
| 1 tile, no valve | 0.3 | Inadequate — painter starves | Add 1 valve |
| 1 tile, 1 valve | 0.7 | Better but still bottlenecks | Add second valve |
| 1 tile, 2 valves | 1.0 | Full throughput — optimal | No fix needed |
| 10 tiles, 1 valve | 0.4 | Starvation at painter | Add valves every 5 tiles |
| 10 tiles, 2 valves | 0.85 | Near optimal | Add third valve at 7-tile mark |
| 10 tiles, 3 valves | 1.0 | Full throughput | Optimal placement |
| Fluid Launcher to remote painter | 1.0 | Full throughput, no pipe length limit | Use launchers for long distance |
Valve Optimization Strategy
The key insight for valve placement is that valves only accelerate fluid in the pipe segment immediately after them. A valve at the start of a 20-tile pipe only helps the first few tiles. Place valves evenly: for a 15-tile pipe, place one valve at tile 5, another at tile 10, and optionally a third at tile 15. This ensures every section of the pipe has active acceleration.
There is no penalty for using more valves than necessary. Excess valves do not restrict flow. The only cost is the iron required to craft them. Since iron is abundant in shapez 2, the optimal strategy is to over-valve your pipes rather than under-valve them. If you are unsure whether you have enough valves, add one more. The performance difference between 2 and 3 valves on a 10-tile pipe is small, but the difference between 1 and 2 valves is massive.
Buffer tanks are also essential. Place a fluid storage tank between your Mixer and your Painters. The tank smooths out fluctuations in mixer output and ensures the painter never starves even if mixer throughput dips briefly. A single fluid tank can supply 2 Painters at full throughput indefinitely.
Color Efficiency Tier List
Not all colors are equal in shapez 2. Primary colors (Red, Green, Blue) are the cheapest to produce because they require only an extractor. Secondary colors (Cyan, Magenta, Yellow) require a Mixer and two extractors. White is the most expensive because it requires a 3-input Mixer and three extractors. Plan your factory layout with this cost hierarchy in mind.
| Color | Production Cost | Efficiency | Notes |
|---|---|---|---|
| Red / Green / Blue | 1 extractor | Highest — primary colors | Always extract directly. Never mix primaries from other primaries. |
| Cyan / Magenta / Yellow | 2 extractors + 1 mixer | Medium — secondary colors | One mixer can supply 2 Painters. Buffer with fluid tank. |
| White | 3 extractors + 1 mixer (3-input) | Lowest — tertiary color | White is the bottleneck in most late-game factories. Dedicate extra mixer capacity. |
| Crystal (Clear) | 1 Crystalizer + crystal deposit | Medium-High — special fluid | Crystal fluid is separate from paint. Requires Crystalizer, not Mixer. |
Common Throughput Bottlenecks and Fixes
- Painter starves despite connected pipe. The pipe has insufficient valves. Add valves until you have at least 2 per 10 tiles of pipe. Also check that the fluid source (Extractor or Mixer) is actually running — a paused or unpowered source will not send fluid even with perfect valve placement.
- Mixer cannot keep up with Painter demand. One Mixer produces 0.5 fluid per second for secondary colors and 0.33 for White. One Painter consumes 0.5 fluid per second. Therefore one Mixer can supply at most 1 Painter for secondaries and less than 1 for White. Add more Mixers or use fluid buffer tanks to decouple mixer and painter timing.
- Fluid backs up at the Mixer. The Mixer output is clogged because the pipe network has no outlet. Check that all painters on the pipe network are actually accepting fluid. A single blocked painter can cause the entire pipe to back up and stall the Mixer.
- Crystal fluid throughput too low. Crystalizers have the same throughput as Mixers (1.0 fluid per second) but crystal deposits are rarer than paint extractors. Build your MAM near crystal deposits rather than piping crystal fluid long distances. If long-distance crystal piping is unavoidable, use a Fluid Launcher.
Frequently Asked Questions
Q: How many Painters can one Mixer supply?
For secondary colors (Cyan, Magenta, Yellow), one Mixer produces 0.5 fluid per second and one Painter consumes 0.5 fluid per second. In theory, one Mixer can supply one Painter. In practice, throughput fluctuations mean you should buffer with a fluid tank and consider using one Mixer per Painter for critical production lines. For White, one Mixer produces only 0.33 fluid per second and cannot keep up with even one Painter — you need 2 Mixers per White Painter.
Q: Should I use Fluid Launchers instead of pipes?
Use Fluid Launchers for any fluid transport over 15 tiles. Launchers have no throughput penalty regardless of distance and require no valves. The downside is that Launchers cost more iron than pipes and take up more tile space. For short runs under 10 tiles, pipes with proper valve placement are more space-efficient and cheaper. For long runs, Launchers are strictly better.
Q: Why is White paint so hard to produce in bulk?
White requires a 3-input Mixer that consumes 1 Red + 1 Green + 1 Blue to produce 1 White. The Mixer throughput is 1 operation per second, so it produces White at 0.33 per second. A Painter consuming White paint needs 0.5 per second. This means you need 2 White Mixers to feed 1 White Painter without a buffer. In a MAM that needs multiple White-painted shapes, the White paint production is always the bottleneck. The fix is to overbuild White mixing capacity: dedicate 2 Mixers per White Painter and use a large fluid buffer tank.
