  1. Do you guys know any? can't find a proper one on Youtube or google for some reasons. How come this feature is so unpopular?
  2. Any tips on blending real shadows with rendered shadows for compositing? Basically I have a 3D object going from a sunny spot to a spot in the shadow of a wall. I rendered the 3D image with hard shadows and without the wall, so my shadows are always hard. I'm trying to mask the real shadows but the difference is too noticable even with a soft mask. I'd need a way for the shadows to blend perfectly when they collide like they do in real life. Hope this make sense.
  3. Solved by restarting the computer, for now.
  4. I have a very weird bug happening to me right now. I can't move any object even though I am on the right tool with object mode selected, I'm not in axis modification mode. I can select an object in the object manager but not in the viewport. If I left clic on the viewport and drag my camera rotate (without pressing any other key). I've seen post online where people had the same issue but no one gave a fix. I can't do a full computer restart now to see if that fix it, but I really wanted to work on C4D today and this is messing up my plans. Changing the coordinate system doesn't work btw. Here is a screenshot, as you can see the axis doesn't even highlight when my mouse is on top of it. I've opened and close C4D many times, and tried to switch projects and start new ones but nothing fix it. I've tried to diable OpenGL but the bug persisted.
  5. I want the wall to block the light but I don't want the shadows projected by the walls. If I render the scene with Alpha shadows ON and multipass with a different object layer for the scene and for the object I want to composite I get an harsh shadow under it. If I render the wall as well I get a good very soft shadow under the object composited but I also get the shadow of the wall which I don't want. How can I fix this without rendering twice and doing a whole lot of masking and tracking in AE for a poor result?
  6. Any tips on improving viewport performance once you have your solved camera after a 3D tracks? What I do is usally get rid of all the red and dark green tracking points, which helps a lot, but I'm wondering if I could do more.
  7. I know how to make a 3D solved camera inside C4D and insert a 3D object into footage where the camera is moving around the 3D object compositied, but I don't know what's the workflow is when you can't do that (i.e. you can't properly solve a 3D camera because you only have a pan or a traveling shot to work with, not something useful for C4D to define the space). To put it simply, I'd like to track a shot with AE in 2D and inport a 3D model from C4D (i've never used the links between C4D and AE but I know they exist and are quite powerfuls). Should I import the 3D model and match the lighting and create shadows in AE or should I do that in C4D and import everything? With the first solution I won't use the workflow I'm used too and I'm not even sure AE has powerful a lighting system for a 3D environment. With the second solution I don't even really know where to start. Sorry it's probably still not super clear... My footage is moving but it's pretty much a handheld shot from the same spot, C4D is unable to make a proper track out of it automatically as there is a zoom, moving objects, and stabilization artifacts, but I think I can manually track it in AE as there is some points that are fairly good.
  8. I have some objects that need to be added to real footage with a 3D tracking. Usually I'd just use an HDR (Photosphere with my phone) of the scene but this time I only have the footage. How would you match the colors and lighting in this condition? I have Octane, and the shots are outdoor and very sunny, without sometimes shadows that would be projected on the object. It doesn't need to be absolutely perfect, just good enough will do.
  9. I want to create a 'fog slowly clearing' effect in Octane using a Z-depth pass that would composited in screen mode onto the actual rendered scene. Basically I want to animate the depth of the z-depth info channel, but I can't do that from Octane settings as there is no keyframing option.
  10. Not sure if this should go under the newbie section. What are the ways to blend animations with C4D? I have a couple of creatures in an idle stance (yet with a breathing motion keyframed by hand) and I want them to start running from this idle stance using CMotion's walk cycle.
  11. What's your technique to resize a rigged character withtout breaking everything? I'm working on a film where I need to either resize a Motion tracker object with a 3D solved camera or the characters I'm trying to compose inside the tracked footage wich are all rigged and all the wrong size. You can resize the bone and the skin by having them under a parent, either a null or the mesh, and resizing the parent not using the scale tool but by manually entering the desired size under the attribute tab. This work ok, but if you have any IK chains it will break usually. If you delete the IK chains, resize, and recreate the IKs it will break as well, which is weird. I haven't been abled to resize the Motion tracker yet, usually the solved camera won't line up or c4d just won't let you. Plus it's very laggy because of the hundreds of tracked points.
  12. fair enough ill give another go then!
  13. I've tried so many times to get how UV unwraping work in C4D, but all the tutorials are absolute garbage on Youtube, and I can't figure it on my own. I've just finished this candle holder and I've been trying to save my f***ing texture for 20min, haven't been able too yet, it's insane how bad UV unwraping seems to be inside C4D compared to the rest, nothing rly make sense. So I'm considering buying a dedicated unwrapping software, is that a good idea? Which one should I get? Or perhas you know a good tutorial for C4D that could do the job? Also whats the workflow at this point in theory? Like should you export a bump and diffuse map? A normal map? I've already done some cplex texturing with Octane on this model and at this point I just want to add some details on photoshop before re-importing it into C4D. If this was to be added to a game (i know it's too high poly for a game but hypothetically) what should I do? Best
  14. I keep forgetting how to do this, for example if I have 20 objects with a vibrate tag and I want each of them to have a different seed from 0 to 19 how do I do that? Also is there a way to apply a random number without using Xpresso for any parameter in C4D? Best
  15. I've been using C4D for a while now and I use the timelime very often but every time I have to mess around with curves it's a nigthmare, nothing really make sense. Sometimes you can move keys or use beziers to do something but then the next key won't let you do that for some reason. Sometimes all the curves of your scene shows up, sometimes only the one you clicked. ALT CTRL and SHIFT modifiers seems to change behavior too, and the icons on top of the timeline make 0 sense to a rookie. Ok no more complaining, where can I learn how to use the Timeline correctly (an in-depth look would be better than a true beginner tutorial because I know a lot of stuff already)?
