What morphing method would you like to use if Shape Keys do not work?

If Shape Keys (morphing through key shapes) do not work or are unavailable, an alternative method of morphing is to use skeletal animation or blend shapes through shaders.

Specifically, morphing can be implemented via vertex shaders, where morphing parameters are passed as uniform variables, and vertices are interpolated on the GPU. This allows flexible control of the shape without the need to store many key shapes.

You can also use skeletal animation, where the deformation of the model occurs through bone transformations, which is often more efficient and easier to manage for complex animations.

In 3D modeling, modifiers can be applied or procedural methods used to alter geometry.
