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.

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

Create 2D Animated Characters with 3D Character Creator Tools and Artistic Filters

3D CC3 TET Character, based on my Oppa Doll Avatar, used as the base for a 2D CA4 character. One of my favorite things to do is to create characters with any type of Avatar/Character creator app. In fact the first test I usually try with these tools is, can I make an avatar of me (or at least my The Extraordinary Tourist persona). Previously I've used 2D character creators like Oppa Doll as a source of artwork for some characters I've made for Reallusion's Cartoon Animator 4 animation studio but 2D character creators are limited to... well 2D. 3D Character Creators While you may think 3D character creators have no place in creating characters for 2D animation there are quite a number of advantages including: No drawing skills required. Render characters in any style. Use an art filter or even hand trace into line art. Need to animate the character in a specific pose or angle? Render out an image of the character in the required angle and animate it in 2D. Quicker to crea

Review: CrazyTalk Animator 3 vs Moho Studio Pro 12

Reallusion's CrazyTalk Animator 3 or Smith Micro's Moho Studio Pro 12. Which of these 2D animation applications is right for you? Regular readers of this blog will know I'm a strong supporter, and fairly proficient user of CrazyTalk Animator since version 1. It's a great piece of software for producing 2D animations from purchased content quickly and, with version 3, is easier than ever to create animations from your own art. Lesser known is that I first purchased Moho Studio Pro 12 (then known as Anime Studio Pro 9) back in October of 2012 and have been upgrading it to the latest version ever since because I believed in it as an application for creating great 2D animation to TV quality standard. As such, it's a much more complex application than CTA3 that I only got around to learning properly late last year. I'm still in the process of blogging my progress . Despite this I feel I've learned enough of Moho to compare it to CTA3 to help you determ

Review: Reallusion's CrazyTalk Animator 3 - Taking a Step Back to Move Forward

GRRR Dog by TET. Can I animate  this guy in CrazyTalk Animator 3? CrazyTalk Animator 3 's bold claim is 'The One-for-all 2D Animation'. Does it deliver? Could it be your 'go to' 2D animation tool of choice? Before I explore those questions I feel a bit of backstory is necessary. I've been using Reallusion's CrazyTalk Animator since its original incarnation that promised quick and easy, 2D animation creation. An idea that was relative depending on what kind of animation you wanted to do. Since my focus has largely been on original character animation my experience with CTA is relative to that. If you wanted to create animated characters from your original artwork, quick and easy didn't really describe the time and effort involved. There was a lot of preparation and considerable time spent rigging its G1 characters.

Three Image Overlay Apps. Do More with Your Reference Images While You Work

PureRef's image overlay in action with Cartoon Animator 4. One thing Cartoon Animator 4 still does not have in stage mode is the ability to onion skin previous and next frames.  For those complete animation newbies among you, onion skinning is the ability to see through the current frame to your previous and/or next keyframes so you can see the progression of your character or object's movement as you create and adjust each keyframe. Usually the previous and next frames appear lighter so your current frame remains the key focus. This prompted me to look for a tool that could overlay an image over my work to use as a reference while still allowing me to work on the app underneath the overlay. I had seen, and even used such apps in the past but it had been some time so I decided to see what was out there, preferably free and/or open source, with versions for Mac and Windows. Overlay 2 There are actually a number of apps that do nothing more than overlay an image but the only one

Stylish Stick Figures for Cartoon Animator 4.2 - New Characters by TET

Stylish Stick Figures by TET. Animating stick figures is almost a right of passage for any animator who has ever made an old fashioned flipbook or discovered the free stickman animator app, Pivot Animator . There's also the hugely popular viral stick figure animation, Animator Versus Animation  and its sequels by Alan Becker that continue to inspire variations more than 12 years later. Back when Vyond was GoAnimate they had a stick figure theme that was popular site wide despite having many other themes with much more refined Saturday morning cartoon style characters. I even had my own stick figure series, Harry Chalk , on GoAnimate. Long story short, I was looking through the Reallusion Cartoon Animator Marketplace and discovered there really weren't any well designed, traditional looking stick figure characters. That's not to say there weren't any at all but I wanted something similar to GoAnimate's stick figures which included full facial features and male and
