Hey everyone, I'm Haruko and I'm a longtime, largely self taught Cinema 4D user. I started doing 3D when I was around 13, before there were things like School of Motion or Motion Design School. I learned from Deviantart, Shadowness and random books from back in the 90's before everything was digital and Youtube was a thing. Anyone else remember this or am I just aging myself? Anyways, I'm a Creative Director that works in branding, packaging, photography and 3D product visualization. My longest, most contentious love affair has been with Cinema 4D. I used it obsessively until I was around 21 and then stopped for basically 9 years after feeling like I wasn't a great fit to work in the CG industry. I got back into it in 2020 when I ended up having a ton of free time cooped up in my apartment during quarantine. I'm really happy to join this community and hope I can help some people out! I use Cinema 4D R23 and Redshift. Here's some things I've made:

If you want to get excited about Volume Builder and Mesher watch this:

There we go, Thanks Cerbera. I'd like to find a good video explaining what exactly volumebuilder is doing, what the difference is between SDF and fog and what these settings are doing. I haven't been able to fully wrap my brain around what these systems do enough to get proficient it at. This is work and gives me a starting point. Thanks again! T

Cerbera; The illustrated example you showed and the explanation you made was good. Thank you for your concern.

Cool, that plugin looks really useful! Thanks!

Welcome Haruko! Really awesome renders!

Welcome to the forum. Nice works like the pearl bag looks great. As for aging, well let's say my first computer was a Sinclare Zx spectrum. 😊

The 'best' quad mesh can nomally be made if you convert to OBJ using MoI (moi3d.com). Its never the same as a natively modelled mesh though. If the CAD file is not too big I'd be happy to make a conversion for you to see how it turns out.

... maybe you could try Quadrangler plugin https://c4dplugin.com/

You're welcome ! I totally agree - remodelling gives by far the best results with these things... CBR

Welcome to the Core 🙂 Very nice renders, particularly the pearl bag one. And good to have experienced RS people helping out ! Enjoy your time here CBR

Your main problem is your choice of shadows. Hard shadows (raytraced) and soft shadows(shadowmaps) are old fashioned basic approximations of what a shadow would do. Raytraced shadows suffer from razor sharp edges, and shadow maps suffer from artifacts based of general scene size, scale, positioning and angles. You have all your area lights set to cast basic soft shadows, for realism they need to be full area shadows. ie. actually cast the proper shadow according to the area light's surface. This fixes 90% of the problem. The final bit is really down to the lights positions. Two low down lights just skimming along the floor would cause the slight shadow line you see, even in real life. Raise them up to help out. Example attached 20210523 LCW Chair 2.zip

I saw a guy on YouTube who had made an aluminium helix that changed radius at the top and went down inside the original helix to join up again at the base. When it spins you get an up down optical illusion. I tried to make it using formula spline - disaster I tried joining 2 helix primitives using FFD to flatten the ends - another disaster Eventually I used a tracer and some XPresso math. Here's the wip -

Jet Fluids 0.10 is now out. A whole bunch of fixes as well as a new PCI SPH solver. More info about what is new can be found on the main website. pci_sph_test.mp4 I also found some time to make an overview video of the changes from 0.09 and 0.10.
