I opened my model and noticed there´s a lot of unnecessary geometry that

needs to be optimized. I modeled a mech model for challenge and there´s

no limit of polygon amount when you do a model just for rendering purpose.

However if you want to use the same model with same geometry in game engine

like Unity then geometry the model needs to be cleaned up and polygon amount needs to be reduced.

Tip: How to get rid of too many polygons?

There´s many ways and you can try with less subdivisions

or use polygon reduction tool.

This depends also of your geometry but if you use box modeling

with too many edges as I did because it did not matter in

rendered model.

For example the bottom middle part (the mechs ass) has

too many vertical edges. So I wanted to start cleaning

up because this was the most obvious detail to start with.

In this case Melt function is best and fastest

way to clean up your mesh.

What is melt?

Melt is a polygon modeling tool that melts edges.

For example this mech has way too much polygons to be used

as a game model so for example the bottom part of mech

has way too many vertical cuts.

1. select edges with loop selection (shift to add more edges).

2. Convert selection. Now let´s convert edge selection to points.

This is important step because you have to be able to delete the points after

Melt function.

3. Now go back to edge mode and select melt.

You will notice the edges are gone but your points are still hanging out there without any purpose.

4. Go back to points mode and just delete the points. Now you have much less geometry.

I hope this helps in your modeling workflow in Cinema 4D. Thanks 🙂
