  1. I don't think he said that S22 was a preview of later release....
  2. "Set Driver" and "Set driven" establishes a dynamic relationship between parameters, and is primarily meant for animation. There is no need whatsoever to use it in this context. This simplest way to do what you want is to use the scale tool on the object that is out of scale in your scene, and get it to a roughly correct scale. You can then use the scale channels in the coordinates manager to make the scale more precise, if necessary, and be sure to use the same scale factor in x, y, and z.
  3. Not sure if this has something to do with your scene setup (its impossible to see from the screenshot where your deformer is located), but why not try using Arnold subdivision (via an Arnold parameters tag on the relevant geometry) instead of SDS objects? It will look exactly the same, and will make your scene lighter to work with...
  4. If that simple a scene is 1.5 GB, then something is very, very wrong; I would guess that a proper set up scene of that complexity would be no more than 10 Mb. Are the models optimized? This is especially important for dynamics... I would look at the detail level of your main objects. Simplify the heck out of them, and only use a level of detail that is necessary for the scene. If you can't figure out how to do that, then make simplified proxy objects (e.g. primitive cylinders) for the dynamics calculations, and use constraints or parenting to get the high-detail objects to follow...
  5. Since you are on Mac OS, Octane will only work in a very limited number of circumstances: - You have a qualifying Nvidia GPU (which most likely means that you have an eGPU chassis with some sort of GeForce card in it) - You are running Mac OS 10.13.x (so that you can run the Nvidia drivers and CUDA; they won't work in Mac OS 10.14 or 10.15) The Octane Devs are working on a version that will run in Mac OS 10.15.5 with AMD GPUs, but it is not available yet.
  6. This seems like a perfect opportunity to use the volume tools to build your meshes. Put your text/artwork spline objects (or those objects within an extrude object) into a volume builder object, and then into a volume mesher. Adjust the volume builder settings to get the level of detail you need, and experiment with smooth layers if necessary to get the melty/gooey quality.
  7. Apply soon. Some of the programs are first-come, first serve, and the money is finite... I never thought I, as a Canadian, would be giving unemployment advice to a US neighbour...
  8. Don't assume that; if you are in the US, the recently passed Coronavirus Aid, Relief and Economic Security (CARES) Act explicitly expands unemployment coverage support to the: "self-employed, is seeking part-time employment, does not have sufficient work history, or otherwise would not qualify for regular unemployment under State or Federal law...." "Under this provision of the CARES Act, a self-employed person will receive the weekly payment that their state normally provides under unemployment compensation insurance plus $600. The benefit lasts for up to 39 weeks."
  9. Hi all, I just wanted to let you know that I have released a new version of my free python script for C4D: NeuronBuild. This script allows a C4D user (there is also a separate version for ZBrush) to import neuron morphology data from NeuroMorpho.org. It creates realistic, accurate models that you can use in your illustrations and animations, either directly or as the basis for further modelling. There are more than 100,000 entries in the NeuroMorpho repository, across numerous species and cell types. You can learn more, and download the script at: https://github.com/NWoolridge/NeuronBuild A video on the new features is available at: https://vimeo.com/391015129 New in this Version: • I added options to put the model into a volume builder and volume mesher. This will simply create a single mesh that can be used for further modelling or to get better shaded results when rendering. NOTE: the resolution is set deliberately low, since the volume mesher could create many millions of polygons and potentially crash C4D if you are not careful. So, once the model is created, adjust the Voxel Size attribute of the Volume Builder object downward in increments until you are happy… • I added the ability to create a single spline object from all the dendrites, axons, etc. (and a single rail spline as well). This can be used as a proxy for the full model, or as a path for animations of signal impulses, or in a mospline object to create growth, etc. Right now these are created outside the main hierarchy, but I may want to change this... • I fixed an issue where astrocytes and other glia wouldn’t make a model. • I fixed some bugs where odd combinations of the options might create weird results Things to keep in mind: • The detail and dimensionality of NeuroMorpho entries varies significantly, depending upon the techniques used to collect the data. Some entries result in a relatively flat, or only minimally 3-dimensional, model; this may be because the neuron itself is largely planar in structure, or because the data was collected from a single view. If you are unhappy with the morphology of a cell you downloaded, try another! Please let me know if you have any issues, or would like things to work differently. Since it is open source, you can also contribute changes if you want! Best, Nick
  10. There are useful models based on imaging data at the NIH 3D Print Exchange: https://3dprint.nih.gov, though many of the heart models are based on pathologies: https://3dprint.nih.gov/collections/heart-library Many of the models on general commercial sites like turbosquid are terrible (brutally inaccurate, based on plastic models or illustrations, low detail, etc.). Creating an accurate model is hugely time consuming and requires consultation with an anatomist and access to imaging. Below are two very good quality hearts (which I happen to know were built to high standards) that you might be able to inquire about licensing: https://3d4medical.com/apps/complete-heart https://medmovie.com/3203-review/
  11. Just so that I am being helpful, rather than just carping about accuracy: If you are using Cheen, consider rebuilding that shader with a standard material. It's much more flexible, and can even render faster... See example attached. I've more or less recreated the cheen shader, and added ambient occlusion (which cheen doesn't support. Cheen is one of the ancient Bhodinut shaders, which should be be avoided now, and which can be more flexibly be recreated in the standard (or node!) material system. Cheen_compare.c4d
  12. That image was created by the Center for Disease Control, and based on the structure of SARS and MERS, which are very closely related viruses. Multiple copies of the 2019-nCoV have been sequenced, and they all show very close sequence similarity for the major features (e.g. spike proteins). This means that the illustration is pretty accurate...
  13. Virus spike proteins (and other proteins like env and hemagglutinin) are not continuous with the surface; they are distinct objects embedded in the viral membrane (as in you reference image). So maybe just show them as distinct... It would be more accurate.
  14. Just to be clear, OpenGL isn't trashed. It is still there (as is OpenCL 1.2), and will be for the foreseeable future. Apple have just said that it is deprecated, and will eventually disappear (after some years, in some future version of the OS). But that is what the whole industry is saying.
  15. I'm glad MAXON is re-evaluating their educational strategy, and I hope they get on board with the approach taken on by other major vendors. I've had exactly the same frustrating conversations with chairs and directors that hikarubr describes. "Why are we paying for this when Maya is free?" For years I managed to justify the purchase of lab licenses, and then I found out that I could have been taking advantage of the grant program (which was nowhere advertised on MAXON's site). It's great that the grant program exists, and I have benefitted from it for several years now, but how are people supposed to know about it? Things should be clear and in the open. It is great to get a grant, but I don't even list the educational grant on my CV. Its just not the kind of grant we are trying to get as faculty. C4D has a lot to offer, and I still advocate for it. But some of these decisions and approaches are really perplexing, and I know for a fact that they put some people off: I've heard from educators who were intrigued about teaching C4D, but dropped the idea when a free educational version was not obvious. Even the small friction of contacting a rep to discuss lab licensing was too much, and they just went with the "industry standard" which made obtaining the software simple and clear.
