<h1>Flex Splines</h1>
<p style="text-align:center;">Break the boundaries of vanilla construction! Build longer, tighter, and more complex logistics networks that snake through your factory with total freedom. This mod adds lenght to vanilla buildings and adds new flex buildings that can be in strange forms.</p>
<div class="feature-grid">
<div class="feature-card"><b>Extended Reach</b><br>Longer conveyors, pipes, tracks, hypertubes and powerlines.</div>
<div class="feature-card"><b>Custom Splines</b><br>Unlock unique building shapes via Hub milestones.</div>
<div class="feature-card"><b>Tight Spaces</b><br>Curvature freedom for compact, high-density layouts.</div>
<div class="feature-card"><b>Unlimited Flow</b><br>Defy standard gravity and placement restrictions.</div>
</div>
<div class="warning-box">
<b style="color:#fff; text-transform:uppercase; display:block; margin-bottom:5px;">⚠️ Build with Care</b>
Pushing splines to extreme lengths or curves can cause visual glitches or unexpected behavior due to game engine limitations. Use flex buildings when vanilla options won't suffice!

Frequently Asked Questions
Flex Splines - Longer Belts not working after update – what to do?
After a Satisfactory update, mods need to be updated. Check ficsit.app whether Flex Splines - Longer Belts has been updated for the new game version. With Mado Hosting: open the mod manager and click "Update All". If the mod hasn't been updated yet, temporarily remove it so the server starts.
Flex Splines - Longer Belts causing crashes in multiplayer – solution
Most common cause: all players must have exactly the same mod version installed. Check server logs for "ModMismatch" or "Version Conflict". Ensure all players use Flex Splines - Longer Belts v1.0.31 and the same SML. With Mado Hosting, Satisfactory servers run with 6 GB RAM for stable multiplayer performance.
Is Flex Splines - Longer Belts compatible with other Satisfactory mods?
Flex Splines - Longer Belts uses the Satisfactory Mod Loader (SML). Generally, SML-based mods are cross-compatible, but mods modifying the same game systems can cause conflicts. Test new mod combinations on a backup save. The Mado dashboard automatically detects known conflicts and warns you.
