Grant, looks good.
Can we get a higher res version of that image showing all the materials rendered?
Was going to do my own, but... time etc

Is the download section up and running yet?

Yep, uploading them for you right now.

If one wants to do speed tests and such would it be technically possible to convert your materials to other engines? I got the impression they are at least somewhat procedural?

Everything but bercon maps and the functionality with the custom falloff curves is currently translatable to Maya. I'm currently working on some tests before we lose our maya license in a few weeks!

Ah yes, the classic drug-dealer trick, give the first 'hit' away for free and they'll be back as customers!

I watched episode 1 and immediately bought the subscription, although the materials alone are worth the sub fee. Looking forward to seeing what you come up with next

Thanks mate! It's going really well, I've had a second surge of subscribers since the website has gone live so I'm really happy.

Hey Grant, great tutorial...thanks!

Just wondering is it important to do test renders following your method at the final output resolution?
I'm not sure, but am I wrong to assume that the image sampling is linked to the amount of pixels being output?
I know from experience that you can dial down the GI settings a bit when doing very large renders, but not sure about the other sampling (lights, mats, DMC)

Cheers

I definitely do region renders at full res throughout the job and only push out low res tests for clients.
The way the AA works is based on the pixel information so a larger render means more spread out pixels = less potential work for the AA engine.

Great stuff Grant! Really appreciate you putting out the first video for free, hope it translates to a lot more subscribers!

I've had a chance to put some of these approaches to sampling into practise recently and can definitely see the merits of being able to tweak each noisy aspect in isolation. That said, in the tests I've done between this and my normal approach (8 subdivs across the board, image sampler tackling pretty much everything) I've only noticed a marginal saving in render time (2 mins down to 1:50 for example) which is arguably negated by the time it would take me to refine the separate subdivisions for each light, material...etc.

I still need to do more tests as there's every chance I'm missing something (or just stuck in my ways). It could also be that I'm used to having to add noise to images to help with artefacts/banding when things hit CMYK, so I'm less fussed with noise in my renders. I'm curious to know if this is something you start tweaking straight away or do you use rough settings and then clean everything up once you start taking things to final?

lesson 3 covers advanced scene optimisation. Peter Guthrie used your version of settings but I effectively reduced his render time 25%!

My method seems to have substantial benefits across all scene types so far.

Is Grant on Twitter? Ignoring that, what you're describing is a manual retweet which is generally considered bad practise, it's better to use the RT button which allows the original tweeter to keep track of shares/favourites and allows for the full tweet to be seen in its original context. Unless I'm missing something and there's a tweet link somewhere that's over 140 characters

I vowed never to own a twitter but god have mercy on my soul I considered it today!

Yep.... missed it. Cool thanks, sorted now.

You can also access the highres material previews in the subscribers sections.

I have massive plans for improving lighting and material previews at the moment. Going to struggle to get time but picture a dedicated page with previews from multiple HDR's, downloads for the HDR's themselves, generated color palettes and different geometry previews all in one tightly organized area.
