problem with blend shape
the base object is a surface
the target object is a mesh that i import from an OBJ file when i change the blendshape channel key ( to any value other than 0), the object just disappears and one more thing blend shape also doesn't change the texture and the material of the object, then how? pls, help me, i'm doing this for my school project |
I might not be understanding correctly, but it doesn't sound like you're using the blend shape right... it only works if you are blending between 2 identical (on a mesh level) objects. For example, a duplicate of the original object that has had its individual points moved around. The original can then blend its vertices positions to the copy's.
As for changing textures and materials, you'd probably need to use a layered shader and key the transparancy between them. Hope that made sense. |

You'd most likely need to fake it, using blend shapes or another kind of deformer (or combo of deformers) to get object A to move toward the shape of Object B, but then blend transparancy between the two objects.
Using particle effects and the like to help mask the switch can help the overall effect as well, depending on what exactly you're trying to do. If you really want to try to make one shape blend into the other, you'd have the best results doing a blend shape, but you'd have to duplicate object A and then remodel it into object B without adding/subtracting geometry. |

let me make it clearer,
i want to blend the left one to the right one, can anyone help me? |
Make your flat plane have a LOT of geometry, duplicate it, and then go over the copy with the sculpt tools to get it to look like you want. Then you can make a blend shape between the two.

Just a question -- are displacement maps keyframable?
If so he can create a Normal Map between the two objects, use http://66.70.170.53/Ryan/heightmap/heightmap.html that tool to turn it into a displacement map, then animate from off to on (or from 0 displacement to whatever displacement he wishes) It won't use Blendshape, but should get the job done in that situation. (while at the same time keyframing between the two shaders) |
I believe it is possible to key such a thing, but I believe it would take a lot longer to render.
