Learning Reallusion's iClone 5: Part 4 - Rigid Body Physics

Sorry to my regular readers for not posting for some time. Unfortunately when Animation 4 Business is good I don't get all the time I need to post regularly here. I've also been struggling with the latest iClone 5 Quick Fix Tutorial, Rigid Body Physics, which should have been simple but ended up with me seeking help on  Reallusion's Forums.

If you're interested in iClone and was wondering how hard it is to learn then that's what this series is about, my experience of learning iClone 5 using Reallusion's Quick Fix Video Tutorials. Click the following links for Part 1, Part 2 and Part 3. If you're just looking to learn iClone then skip this and try the tutorials for yourself as this series is not a how to guide for iClone 5.

The Rigid Body Physics tutorial demonstrates how to construct a simple car crash into a stack of barrels. Everything is set to the default settings so it's mostly a case of just dragging the relevant barrel props onto the stage and then setting up the jeep iprop to crash through them... except, in my case it wasn't.

This 3 and a half minute tutorial was meant to be simple...what?

So, setting up the barrels (which are already saved as physics props with predefined settings) was straight forward enough. As was setting up the jeep and putting in place a prop that's known as the infinite plane.

To explain the infinite plane it's essentially an area that you define that acts as a barrier that props with physics properties can't penetrate. A typical example, and in the case of this tutorial, is the ground. Without the infinite plane defined those barrels drop through the ground into an infinite hole.

Trouble is, when I put my barrels on the infinite plane they didn't sit still. They kind of jiggled around... a lot. In fact it moved them around so much that my barrel stack fell down. I played around with quite a few physics settings but in the end went to the Reallusion iClone forum to find answers.

One forum suggestion was that the World Scale was set too high. I'm not too sure what that setting represents but the lower the number the less pronounced physics simulations are. For example on the lowest setting it had the effect of making everything move in slow motion.

Lowering the world scale did fix my barrels but not other physics props I experimented with. Take a look at the video below where I have barrels set up and, in the distance, cardboard boxes and wooden crates further down the road. Notice the barrels are still but the boxes and crates are moving around despite not being touched by anything.



The next forum suggestion was to set the barrel's physics profile to frozen rather than dynamic. Personally I don't quite understand the different profiles, there are four in total. The other two are kinematic and static.

I was advised on the forum that dynamic physic props are more sensitive to other physics props within their proximity whilst frozen physics props only react when something actually bumps into them. In any case, changing the barrels profile to frozen seemed to do the trick and worked with my boxes and crates too. See the video below. I also set the World Scale back to its original setting.



I got a good tip on the forum that rendering your video on the By Frame setting instead of Realtime gives better results with physics simulations. Which appeared to be true as fewer of my barrels, boxes and creates seemed to drop below ground level with this setting adjustment.

Honestly, I expected to breeze through this tutorial but the default settings of my physics props didn't act like those in the tutorial. I still don't really know why? I've followed the tutorial step for step several times, creating the exact scene in that video but not getting the same results as those of the video.

The next tutorial deals with Soft Body Physics. I haven't even looked at it yet but I hope it proves to be a little less baffling.

Voice All Your Own Animated Characters with Voice Changer

Voice Changer by AVSoft is real time voice manipulation software that can be used for a wide range of purposes including (according to their website); Voice-over and voice dubbing for audio/video clips, presentations, narrations, voice messages, voice mails, E-greeting cards, broadcasting, etc.; mimic the voice of any person, create animal sounds, change/replace/remove voices in songs, videos,etc. I bought it for the specific purpose of changing my own voice, to extend my vocal range, for voicing characters in my own animations. I was fortunate enough to get this software at a significant discount that made it difficult to refuse, given that I'd never tried it, or even heard of it before. I'm not sure if I would have bought it at the full price given that much of what it can do (for my needs) can also be done with the freeware audio program, Audacity . AV Voice Changer Interface. Voice Changer is relatively easy to install and set up. Once installed simply

Should You Buy or Upgrade to MOHO 13? *Spoiler* Yes. Yes You Should!

MOHO 13's New Character Set. Smith Micro released MOHO 13 , their all in one, 2D animation studio, this week. The question is should you buy or upgrade to the latest version? Obviously I've already spoiled this in the title, so the actual question is why do I think you should buy or upgrade? To be clear, I'm only talking about MOHO 13 Pro. If you're considering MOHO 13 Debut be aware that you're missing out on some of the new features, and a lot of existing features that are only available in the Pro version. Debut is fine if the budget doesn't stretch to Pro, but, if you never want to be disappointed about not having a feature, it's Pro or nothing! The other thing I need to be transparent about is I'm not, by any stretch, a frequent MOHO user/animator. However I took the time to learn MOHO 12 Pro fairly extensively, blogging about my process and sorting out 104 free MOHO training videos into a logical viewing order in the process. I think I ha

Make Disney/Pixar Style Characters with Reallusion's Character Creator and Toon Figure Bases

The Extraordinary Tourist Classic Coat outfit created using Reallusion's Toon Designer for CC3. I've talked before how I've wanted to get into 3D Disney/Pixar style character animation since I first saw the animated cutscenes for the very first Tomb Raider game back in 1996. It's why I initially bought Reallusion's iClone 3D studio app as soon as I could afford a computer that would run it. But then Reallusion released their 3D Character Creator (CC) for iClone and I wanted to create my characters with that (and I did try with Bat Storm ). But the focus of CC was realism, even with ToKoMotion's stylised body morphs . Now with Reallusion's Cartoon Designer bundle for CC3 which features two packs, Toon Figures , and Toon Hair , designing Disney/Pixar style 3D characters just got a whole lot quicker. The two packs are the bare essentials for creating Toon style characters. Five body morphs (2 male, 2 female, and one adolescent body morph that w

Animation 4 Business iClone Promotional Video

In my recent updates I've been teasing a new Animation 4 Business Promotional video created with Reallusion's iClone 6 . It's taken me longer than expected because I've only been able to work on it for a couple of hours each day - part of my new schedule that enables me to work on many projects concurrently. Finally the animation is finished and, although I've already debuted it on the Animation 4 Business website , Facebook and YouTube, here is the only place you can read about the behind the scenes creation process.

Voicemod - Free and Easy to Use Voice Changer/Modulator Application

Voicemod is a real time voice changer app. A common problem for hobbyist animators is finding people to voice characters. Friends are often called in to our no budget productions because they're friends and they're usually happy to help. However friends aren't always available and/or willing, and hiring voice actors can be expensive if you're making a lot of short animations just for fun. In desperation you start voicing all your own characters but quickly realize your vocal range extends to only about three different voices. This is where  Voicemod  may help. Voicemod is a free dedicated, real time voice modifying app for Windows (other OS's are in the works). It has a very simple interface that makes it easy to alter the sound of your voice to any saved voice profile with a single click. It also makes it very easy to modify any profile or even create your own voice modifications from scratch. Before I go further, while Voicemod is free you are limited

Learn Moho Pro 12 Free Using SmithMicro's Own 104 Video Tutorials Sorted into a Logical Order of Progression

So you've bought Smith Micro's Moho Pro 12 along with the Moho, 10 hour, 104 Video Tutorials Add On pack so you can get learning right away... only you can't. For whatever reason, the video tutorials aren't sorted into any logical order of progression making them hard to follow. Yeah, I've been there, only I've done what Smith Micro should have done and sorted all the video tutorials into a logical order of natural progression for you. That is, each tutorial builds upon what you learned in previous videos and you won't suddenly come up against some feature you've never used before, unless that feature is what the video tutorial is about.

Eric W. Schwartz: Cartoonist, Animator and Amiga Die Hard

July 1992 Edition, CU Amiga Featuring Amy the Squirrel. American Cartoonist, Eric W. Schwartz , (whose unofficial Amiga Icon, Amy the Squirrel, is pictured on the July 92 edition of CU Amiga cover on the right) is my only real animation hero. Sure there are the big names like Disney , Chuck Jones , Tex Avery and even Preston Blair whose influences can all be seen in my own cartoons but Eric did what none of the others could. He showed that really great 2D computer animation was within my reach with little more than an Amiga Computer , a copy of Deluxe Paint and Moviesetter . This was at a time when computer based animation was in its infancy (outside of computer game animation) and Flash was something that lights did. There were many great Amiga artists but Eric was really the only one consistently making very funny, traditional style animations. His humor and drawing style is heavily influenced by classic Warner Brothers and Disney cartoons but he managed to build on this,
