If a procedural texture is very noisy and appears to shift, try increasing the Filter and, or Filter Offset values to try to achieve a slightly blurred effect and to reduce the sharpness that causes the swimming. You can also try increasing the Shading Samples as a last resort.
If a texture does not stick to a deforming surface, try the following:
| Option | Advantage | Disadvantage |
|---|---|---|
| Turn on "local" on the 3d texture or projection. | Simple, fast, uses minimal memory, and works for multiple objects. For example, the texture would move correctly with each of many asteroids even if the asteroids are moving in different directions. You don’t need to group with objects. The texture can also be animated. | You cannot customize the placement for different objects. Complex object hierarchies appear seamless only if you do a zero transform on the object first. It does, however, move with transforms on sub objects, such as the arms of a robot.The placement node does not reflect the actual position of the texture, which additionally is transformed to the position of each object (at render time). This method does not handle morphing surfaces. |
