Your sprite 3D model (like a plane with a sprite texture) is distorted in Blender mainly due to three issues: incorrect UV mapping, a mismatched texture aspect ratio, or non-uniform scaling.
- Incorrect UV mapping: If UVs don’t fit the sprite’s size, the texture stretches over the model. - Mismatched aspect ratio: If the sprite’s width/height ratio doesn’t match the model’s scale, the image warps. - Non-uniform scaling: Stretching one axis more (e.g., pulling a plane vertically) distorts the sprite.
To fix this, align UVs to the model’s faces in the UV Editor, match the model’s scale to the sprite’s aspect ratio, or apply uniform scaling (Ctrl+A > Apply Scale) to remove uneven stretches.
