When your point cloud 3D model shows weird shapes in Maya, it’s usually due to low point density, incorrect import settings, or Maya’s default viewport struggling with sparse data.
Low density creates gaps or uneven points that look distorted; wrong import settings (like scale mismatches or incompatible formats) misalign points; Maya’s viewport often renders sparse clouds poorly by default.
Fix it by increasing point density in your scanning/export tool first, or adjust Maya’s Viewport 2.0 settings (e.g., raise point size or switch to "Points" mode) to smooth the shape.
