In order to become better at Maya we need to have a better understanding of what's happening "behind the scenes" in Maya. How the node network functions and how Maya automatically connects, disconnects, deletes, etc nodes in your scene. This is a really quick look at a simple shape node network, and what is really happening when you delete history.
this is a bit of a rambling video but I hope you find it useful.
I was working on an ident recently where I needed some geometry to have an undulating surface and when it was done a few people asked how I had done it.
It's a pretty simple technique and probably obvious to some but if you don't use deformers much this might help you to get experimenting.
Something I should have mentioned in the video is to try experimenting with different noises and scale, as you will get very different results.
If you want to see my cineware technique leave a comment and I'll see how popular an idea it is.
A favourite topic and one that keeps coming back is how to effectively destroy objects in Cinema 4D. There are a huge variety of methods and tools available for this, some use clothilde, others purpose built plugins but there are a few ways of doing it with just the standard tools.
This is just one way but it works great, is simple to set up and is really versatile. Works with any mesh as well, so if you have complex objects to destroy give this a try.
Try it out and see what else you can come up with using other mograph tools or standard effectors.
