Physical material tutorial

<< < (2/3) > >>

ShahynRox:
I appreciate the new initiative for more tutorials as it is a still a desideratum for C4D users. But the “design” of the tutorials is not ideal. In my opinion the videos are far too long compared to the low amount of content. Too many repetitions and redundant information. I do not need to hear every 5 sec that the physical material is much smarter and much more realistic than the legacy material. If you do not explain WHY, it is enough to say that once and then bring relevant information how to use it. Try to condense the explanations to the real core information so that the videos are 5 minutes long. The first “tutorial” is 12 minutes long and has no info that is worth more than 2 or 3 minutes. The same with the second video (17 minutes!). You could communicate all relevant information in 5 minutes. The time saved could be used to produce more tutorials on other features of Corona for C4D.
I hope you do not misinterpret my critical review of the tutorials published so far. I really hope to see more videos! So thank you for the effort!

This is great thanks, I've wanted to know how to use the physical material properly so this tutorial series is much appreciated. When are the next ones coming out? (looking forward to seeing more). :)

I have watched a silly amount of tutorials over the years and I think these are pretty good. I understand what @ShahynRox is saying but think at this stage the introduction videos are fine. (I didn't personally find them too long and I have a short attention span) :)

I think the gold standard in my opioon for tutorials is MographPlus. The key for me is the videos are broken down into sections and are kept as short as possible so I can quickly find a specific section that I'd like to learn.

I was wondering if the youtube videos can be arranged differently so its easier to see if they are for 3DS Max or Cinema 4D? So for example having a separate youtube for Corona C4D/ 3DS Max or just separate playlists?

You are welcome! Yeah, the clearcoat tutorial is still on the way and I'm hoping it'll answer the rest of your questions. Clearcoat to me is one of those things that once you "get" how it works you really start to realize just how many things you can do with it.

@ShahynRox
Howdy! This comment definitely comes off as constructive criticism and we're happy to hear feedback like that, so thank you!

We'll keep that in mind for future tutorials and future series. That said, to give you a little background on why we've decided to make these longer rather than shorter... Well, this series is designed to be all about the basics - and we're hoping these will be a good starting point for novice users as well and so we've figured it's better to say more rather than say less.

There's more content planned besides this series so we plan on covering lots of different topics in the future. And as a tidbit of production info, the length of these doesn't really affect the time needed to get them out the door. Surprisingly so! :)

@ianosss
Thank you for your feedback as well! Appreciate the references and the kind words!

I'm really glad that you're making these films. It's definitely needed!

To agree with ShahynRox some of the simple stuff can be moved over a bit quicker. Most users are not rank beginners.

The real need is to address some of the new ways of working - which to existing users are definitely not more intuitive.

Example below...  a simple bottle with greenish glass where it's thicker. Simple using the legacy material.
But the same settings give a completely different result in Physical. I have no idea how to set up my glass now - so just stick with legacy 99.9% of the time.

Can you enlighten me?

Thank you for the feedback, appreciate it!

For your particular example, I'm guessing you have the roughness set to a value quite a bit higher than 0% which is making the material ... Rougher.

We'll tackle this in the upcoming tutorials in the series but the roughness parameter affects both the roughness of your reflections as well as your refractions. So set that to match what you have set in the refraction channel in the legacy material and it should look similar. The physical MTL does use a different physical model for calculating refractions so values that aren't 100% glossy won't match 1:1, you'll probably want to tweak those slightly.
