CGTalk - Animating morphs

Wanting to do a morph animation between a human and creature. I have 2 OBJs, each with its own displacement map, sort of a before and after.

Firstly I tried to replace the RVK of the base mesh with the data from the second mesh using the Copy RVK script but it didn't work (copied from the base to second mesh OK, but not the other direction). Not sure what I did wrong or even if it works at all. Other apps have the ability to "blend" from one mesh to another - is this something that may be in the pipe for Blender?

Secondly not really sure how to animate the transition from one material (including texture and displacement map) to another - anyone been able to do this ?

Any help would be greatly appreciated.

Thanks.

To make a mesh morph from one shape to another, you would use the shape keys. Im not sure about the copy RVK script I havent used it, but I do know both models would have to have the same number of verts. The best way would be to create a shape key on one of the models and model it to your desired changed shape.

You cannot change textures on a mesh during animation. But a way to do this would be to add all the textures, and blend one to transparent while blending the other to full visibility over time.

First, I´m quite surprized that you was able to copy one mesh RVK into the other, considering that you started with to very different meshes. Usually I would anwser "that's impossible!", but you said you got it working, so I´ll play along.

RVKs are IPOs, if you currently have A morphing into B, all you need to do is to invert the IPO and you´ll have B morphing into A, problem solved !!
