#BLENDER DMESH HOW TO#

I've already worked on adding a morph-distance limiter: The morph change get's smaller and smaller as you get farther away, eventually stopping the morph action totally. I'm not sure why it does that, but anyone with ideas let me know ho to fix it.Ĭode follows, as does a sample file for Unity.Īnyone else tried this and have ideas on where to go from here? When using this with non-static meshs, it seems to permanently distort the mesh unless reloaded from the original files. It's a good idea NOT to have shapes change across a UV map. UV seams can break up slightly, leaving tiny gaps. Now, what kinds of issues does this system have? breathing organics hanging from the walls and ceilings. Doors that peel back from a monster's attack. If everything was done right (and I didn't screw up explaining it) then you should see the mesh animating. Inspect the Difference Map texture, and make sure that 'is Readable' is checked. Add the Difference Map texture to the script using the scrip menu in the inspector. (It can work with skinned meshes, toggle the IsItStatic variable from 1 to 0 for bone animated meshes) Drop the Diff_Map_Animator.js into the object. import the base model into Unity like normal (this can ever work with skinned meshes), and import the 'Difference Map' texture you just saved. convert the vertex color into a texture (using a material set to 'VCol Paint' and 'Shadeless', and then using Bake as a texture. The differences are recorded into the changed mesh's vertex color maps using rgb colors. You run the Diff Map Maker script, and it compares them. You select the Base mesh (cube) and then shift select the changed mesh (sphere). make sure the sphere does NOT have a vertex color layer.

Could be larger or smaller than the cube, depending on what you want. Then you copy the object (cube) and shape it into a sphere. You set up it's texturing, UV mapping, everything. You make a base mesh, a detailed cube for example. It them allows you to animate the mesh based on a range of 0.0-1.0

The Unity script reads the texture, and learns how to move each vertex based on rgb/xyz movement per vertex. This includes a blender Python script that takes two meshes, compares them, and applies the difference to the mesh's Vertes color. I got tons of help from Unity forums, and darn little from Blender/Python scripters.īefore I hand over the scripts, let me offer a rundown on how this works, limits, and what we can hope for.ġ. All right, this took weeks/months/an annoying amount of time.
