Users consistently report that Blender has one of the steepest learning curves of any creative software. The complex interface with hundreds of hotkeys and non-standard controls makes it very difficult for newcomers to get started. Many quit within the first few projects due to information overload.

The UI is described as awkward with options cluttered everywhere. Non-standard mouse actions and heavy reliance on keyboard shortcuts make it feel unintuitive compared to other 3D software. Users coming from Maya or Cinema 4D find the workflow frustrating initially.

Users complain that UV packing is terrible for efficient game layouts and there's no quick way to visualize UVs on 3D objects. The texturing workflow is considered less intuitive than dedicated tools or competitors.

Blender uses non-standard keyboard shortcuts and workflows that don't match industry conventions. Professionals trained on Maya, 3ds Max, or Cinema 4D face a relearning curve, and collaboration with studios using other tools can be challenging.

Modifiers don't use the axis of the mesh they're applied to, requiring users to create empties as workarounds. This adds busy work and confusion, especially for users coming from other 3D software with more intuitive modifier systems.

When you create an object and click on something else, you can no longer adjust its parameters. This isn't a big deal for simple meshes but becomes frustrating for complex procedural objects like trees where you need to tweak settings iteratively.

While Blender includes a built-in video editor, many users prefer dedicated editors for advanced work. Blender's editing tools are less intuitive and lack features compared to specialized video editing software.

Even with dedicated GPUs (4GB+ VRAM), Blender becomes slow when adding layers and complexity to 3D models. Viewport lag and slow render times frustrate users working on larger projects.

Users report that the new EEVEE rendering engine is significantly slower than the legacy version for viewport navigation and volumetrics rendering. This regression affects daily workflow speed for many artists.

Users report frequent crashes during Cycles GPU rendering, often caused by VRAM limitations, TDR timeouts on Windows, or driver issues. Unlike system RAM, GPU memory is a hard ceiling that causes instant crashes when exceeded.

The simulation tools for cloth, fluid, and other physics could be much better according to users. Results can be unpredictable and the workflow for achieving specific simulation effects is often frustrating.

Many addons stop working when Blender updates to new major versions. Users report addons failing to register, installation issues, and conflicts between multiple addons. The transition to the extensions system in Blender 4.2+ caused widespread compatibility problems.

Saving and loading .blend files between different Blender versions can cause problems. Projects created in newer versions may not open correctly in older ones, and some features may be lost or corrupted during version transfers.

While Blender has extensive documentation, users report it doesn't provide enough information on specific problems. Finding solutions often requires digging through forums, YouTube tutorials, or community discussions rather than official resources.
