C4D Models with same vert count

blackburst's picture

For use with the 3d object blend patch, is there anyone experienced in C4D that can tell me how to make two unrelated models have identical numbers of vertices? Surely there's a way to numerically simplify the models, albeit at certain costs. Dust you out there?

I'm not Dust, but you can try the polygon reduction tool. I don't think there's a way to enter in a target vertex count though besides manually editing, and that's not exactly the same as automatically making two objects the same vertex count.

apart from same vertices count, you also need some similarities in the vertices indexing, or you'll end up with a screwed up model anyway.

If someone is lerping between two different models, the main issue will be the transition. It may be that someone doesn't mind a screwed up looking transition. Also, if someone is rendering with points, it doesn't make as much difference, and the transition can be longer without looking stupid.

If the transition is really fast, you don't see much...

Here, there are some unrelated textured models morphing that look sketchy in a couple places, but it's because I hadn't discovered that the mesh creator has a broken normal calculation yet. One can get the correct result by using the get/set mesh patches. These models were manually edited.

mmm, but all your models look screwed up, esp. the clock and the van

Mmm, but as I wrote, "Here, there are some unrelated textured models morphing that look sketchy in a couple places, but it's because I hadn't discovered that the mesh creator has a broken normal calculation yet."

I guess I could make an example just to prove this, but I know it works because I've done it since, so it would be pointless for me... I guess you can choose to believe or not to believe :-)

they are all with the smoothing groups wrong. if you render them faceted they will be ok, but the smoothing is wrong.

Re: C4D Models with same vert count

this happens because the vertex order is wrong. find a way to keep it and you'll be ok...

What? No, here the "look" of the lighting being a bit off is because the normals are calculated incorrectly; I was using the mesh creator, which doesn't handle normals correctly in all cases, and I was also lerping the normals stupidly and not letting them reach the end result (it's like at 99.99% lerped). One can't "render" with the mesh creator in faceted mode, because there is none.

God, I wish I had rendered the damn thing without lighting/not been fancy and screwed w/ normals at the time.

So, I don't know what is so hard to understand about the fact that if one interpolates ALL THE WAY from one data set to another, that the end result IS the end result.

Try it - if you do a mix function, when mix is 0, it's data set A. When it's 1 it's data set B. There is no rocket science involved here.

Re: C4D Models with same vert count

what is meant by "vertices index count" and would one manipulate such a thing?
