How do I optimize my game's assets?

Compress and appropriately size assets, use efficient formats, and load only what is needed (streaming and lazy-loading the rest), so assets do not bloat memory or load times. Oversized, unoptimized assets are a common mistake that hurts both memory (huge textures and uncompressed audio bloat memory, causing out-of-memory crashes on low-RAM devices) and load times (more data to load and decompress). To optimize: compress textures and audio, size assets appropriately (do not ship higher-resolution assets than needed), use efficient formats, and load assets efficiently (load only what is immediately needed, stream or lazy-load the rest rather than loading everything upfront, and unload assets you are done with). This reduces memory footprint and load times. Bugnet captures out-of-memory crashes (with memory and device context, revealing whether asset-heavy memory use is causing crashes on low-RAM devices) and load time data (revealing slow loads), so you can see whether your assets are causing memory crashes or slow loads, optimize them, and verify per version that the crashes and load times improved on real devices, addressing the memory and loading impact of unoptimized assets.

Why does my game crash on a missing asset?

Because an asset that is missing, misreferenced, or packaged incorrectly in the build fails to load, and the game crashes trying to use it, often a build-only issue invisible in the editor (which had the source asset). Missing-asset crashes are common build-only bugs: in the editor, the game loads assets from source (so they are present), but in a build, assets are packaged, and if one is missing, misreferenced, or packaged incorrectly, it fails to load and the game crashes when it tries to use it (a null reference, a load failure). This is invisible in the editor (the asset was there) and only shows in the built game. To find them, capture the crashes from the built game with the stack trace (which points at asset loading). Bugnet captures crashes from built games with stack traces and context, so you can see the asset-loading crashes that only happen in builds (the stack trace pointing at the asset load), revealing which assets are missing or misreferenced in the build, so you can fix the asset references or packaging and verify per version the crashes stopped, fixing missing-asset crashes that your editor would never show because it had the source assets.

How should I load assets in my game?

Load only what is needed when it is needed (streaming and lazy-loading), rather than loading everything upfront, and unload assets you are done with, to keep load times and memory use low. Loading everything upfront (at startup or level load) is a common mistake that causes long loads (all that data loaded at once) and high memory use (everything kept in memory, risking out-of-memory crashes on low-RAM devices). Instead, load efficiently: load only what is immediately needed to start (so the player gets in fast), stream or lazy-load the rest as it is needed (open-world content, level assets, on-demand resources), load asynchronously off the main thread (so loading does not freeze the game), and unload assets you are no longer using (to free memory). This keeps load times short and memory use within limits. Bugnet captures load time data (with device context, revealing slow loads on real devices) and out-of-memory crashes (revealing memory pressure from loading too much), so you can see whether your loading approach is causing slow loads or memory crashes, shift to loading less upfront and streaming, and verify per version that load times and memory improved, loading assets efficiently rather than all upfront.

Common Asset Management Mistakes

Quick answer: The biggest asset management mistakes are oversized assets, missing assets in builds, and loading everything upfront, fix these by optimizing assets, verifying builds, and loading efficiently.

Assets drive memory, load times, and build issues, and common mistakes cause crashes and poor performance. Here are the most common asset management mistakes and how to avoid them.

Using Oversized, Unoptimized Assets

A common asset mistake is shipping oversized, unoptimized assets, huge textures, uncompressed audio, heavy models, which bloat memory (causing out-of-memory crashes on low-RAM devices) and load times. Unoptimized assets hurt performance and stability.

The fix is optimizing assets (compression, appropriate sizes, efficient formats). Bugnet captures out-of-memory crashes (from asset-heavy memory use) and load time data, so you can see whether oversized assets are causing crashes or slow loads and verify per version that optimizing them helped on real devices.

Assets Missing or Misreferenced in the Build

A second mistake is assets that are missing, misreferenced, or packaged incorrectly in the build, so they fail to load and crash the game, often a build-only issue invisible in the editor (which had the source assets). A missing asset in the build is a crash waiting to happen.

The fix is verifying assets are correctly included in the build. Bugnet captures the crashes from missing or failed asset loads in the built game (the stack trace pointing at asset loading), so you can see asset-loading crashes that only happen in builds and fix the asset references or packaging.

Loading Everything Upfront

A third mistake is loading all assets upfront (at startup or level load), causing long loads and high memory use, rather than loading only what is needed when it is needed. Loading everything bloats load times and memory.

The fix is loading efficiently: load only what is needed, stream and lazy-load the rest. Bugnet captures load time and out-of-memory data, so you can see whether loading everything upfront is causing slow loads or memory crashes and confirm per version that loading less upfront improved both.

Avoid the big asset management mistakes: oversized assets, missing assets in builds, and loading everything upfront. Optimize assets, verify builds, and load efficiently.
