  1. OK I got it to work again. I were mostly right. Not the projection, but after I resized it to fit, I forgot to hit Fit to Object again. My method here was the Cloner had the material so it applied to the group of clones. I found this great tutorial from EJ, but it's for R12. I was hoping he could update it for R20 and Fields.
  2. So I have some rings emanating from a Cloner. I want those rings to fade away when they reach a certain distance. I was able to get this one looking right using a circular gradient to fade it out, but when I bring it into the actual scene I need it in, the material just goes all over the place and I can never get close to this example. I was also experimenting with a Shader Effector and gradients, but I'm just running in circles now. Any tips would be appreciated.
  3. I think you need to tell us how this is being animated. Just looking at this makes me thing those straps don't do much because of the weight they're holding. Maybe some basic swaying motion. What else will happen to these straps?
  4. Ha. I need to dig up my old copy of Vertex Pusher "Vol7 Xpresso Demystified." That looks so easy, I'm embarrassed I had to ask. Really the only trick is knowing you can drag a material directly into the window and get total access to everything. Thank you.
  5. I'm assuming you can do this with the Demo, not sure. My first thought would be to flip your project around. Bring your footage into C4D and use the Motion Tracker and get a 3D solve. You can add basic shapes to match the geometry and, using things like Camera Mapping or Render Man, your footage will be mapped onto these simple shapes. These shapes will "catch" your shadows and composite them in right in C4D. In addition, you can also bring your C4D scene into AE after you've done the 3D solve so that camera will be in AE. You can then add 3D layers to get more possibilities. Couple of good tutorials on this: Back to reality. You said you're a noob, so what I'm suggesting is not what you would learn on the first day of C4D 101, but it may be the best option.
  6. I know very little about XPresso, but do have a programmer part of my brain. I was wondering how difficult it would be, or if possible, to connect a toggle or slider to manipulate a field in a material? Even better would be to affect several at one time. For example, let's say you have a car with several different luminance materials and you wanted to animate or simplify the process of turning them on or off. I feel like XPresso could achieve this. Any thoughts how this could be done?

    Apple killing OpenCL, OpenGL

    I know right? It's getting more and more difficult to keep using the Mac for high-end graphics and animation. I'm still holding out for a new tower this year (every digit is crossed) so I haven't gotten a new iMac Pro, which are indeed very fast. But alas, not very upgradable and no choice in GPU. So annoying.

    MoGraph academy award :)

    First time I've heard your name Hrvoje procounced. Ha. I never would have gotten that right. Very cool to see this. I didn't know they gave out Oscars this early before the big show.
  9. @jed Out of curiosity, what car paint presets are you referring to? Also, ANY material with reflection has the same requirement. They all need something to reflect.
  10. So I was able to find a solution to this dilemma. Corona's help system has this text description for the Shadows pass: "Shows the shadows (energy subtracted from the image due to shadow ray occlusion). This is the complement to the beauty pass, showing white where there are black shadows. If this pass is linearly added to the beauty pass, it negates the visible shadows. Note that currently the shadows from environment lighting are always shown, resulting in a washed-out pass in typical interior renders." This doesn't make any sense to me as far as AE goes. My solution was to drop a Shadow Catcher material onto the screen. This produced an inverted shadow map. After inverting it in AE, it almost disappears so I had to add some Curves to get the shadows back. Then just Multiply it back over the new screen content. Funny thing is, I also set up an AO pass to pick up all those little shadows around the edges of the screen. That pass produced a white image with dark gray shadowy bits. Simple and easy. Not sure why the shadows don't come out that way way. I'll post back if they reply with anything to clear this up.
  11. Anyone here that uses Corona know if the Shadow pass from Multipass is functioning? The result I'm getting just doesn't look right. I posted on the dev's site, but with the time difference, it can take quite a while to get a response. The image on the left is the RGB and the image on the right is what I got out of the Shadows multipass. Weird right?
  12. Being a Mac user, I'm out of the loop with GPU drivers. Ha. Since we really don't have any.

    Helical 3d Shape

    Here's an example of what I described above. Seems like you could do some interesting things with this. Helix Idea.c4d.zip

    Helical 3d Shape

    I think the hard part is creating one spline that follows the shape of your model. After that, I would guess you make a Helix long enough to be Spline Wrapped along that spline. Make sure to set it as Keep Length as to not stretch or squash the helix.
  15. I know you said you applied the texture correctly to the object, but my brain goes right to this area. What came to mind was a UV issue or setting to Flat, but it's turned 90° so it is being "smeared" and you're only seeing part of the texture. OR, is your Viewport set to Display as Box? This will give a very basic idea of the texture. Maybe post a screen shot of what you're seeing.
