  1. Water/whitewater flicker with redshift

    Also, you may render with AOVs (passes) and it can help to understand which part of the shading produce an issue.
  2. I think you can project SOP mesh on terrain and then do the simulation.
  3. Solaris camera

    I was thinking if SESI built a new system to manage shots renderings, I would better utilize this system, instead of trying to replicate an old workflow in the new environment. I mean I don`t need to store materials with an asset, even opposite, I like the idea of material library shared between assets and shots. I just have no idea how this system is meant to be used. I saw a couple of Solari's tutorials, but they did not cover this topic on a high level, what I am actually interested in...
  4. Solaris camera

    Sounds like I can stay in Mantra world for now But I am still curious, do you have any idea what would be material assignment workflow with Karma? I guess with Mantra the common practice was to store materials with assets and in LOP`s there is the ability to use the material library and do the assignment right before the rendering in the LOP context using geometry groups. I think SESI designed a very powerful system which should be a better version of Katana, but I am confused about how it should be used at a high level in complex project with a lot of shots.
  5. Solaris camera

    What are the Horizontal and Vertical Aperture parameters in Solaris camera? It's not the same aperture we use to in photography, more like a film size parameter, which is confusing. The F-stop parameter (which defines the aperture size in real camera if I not mistaken) is also confusing, you need to use crazy numbers like 100 and more to get a more or less sharp image. Do those values meant to be completely far away from real camera values? Also, is there a way to save renderings in Karma viewport, as it was possible with Legacy Render View (Add image to History).
  6. Houdini 18 is Out!

    Does Karma available on 18.0.287?
  7. Hair and fur question

    Lucky for us, we can use whatever we need, the data is the same, it`s just personal preference on how to organize it. Take a look here for more info about using shelves workflow.
  8. Hair and fur question

    I guess the main reasons are: structuring your network and provide some out of the box solutions. If you are more comfortable to do all the grooming in SOP it's totally fine, hairs are just curves. You can dive inside the guide groom and hair generate objects and learn some useful techniques (until SESI rewrite them in C++) for your SOP setups.
  9. python folder creating

    print '{1:03d} {0:03d}'.format(1,2) # result: 002 001
  10. Recursive split can provide some good results. You can also generate points around fractured edges and use them in another fracture to get small pieces.
  11. Hair inside mesh

    So if its the case of opposit oriented guides. You can draw the curve on the skin which would be a "divider" for hairs, and plug this curve in the last input of Guide Partition (place it after Guide Groom node) node.
  12. Hair inside mesh

    Ok, for me its looks like an interpolation issue, cos you have guides coming to one direction and guides comming to opposit direction close to them. So in between hairs are a bit confused about where should they grow to. If its the case there is a solution for such a case, I will try to recall what was it...
  13. Hair inside mesh

    Interpolation between guides can be an issue as well. Do those penetrating hairs are far from the guide? The guide process nodes should take mesh into account as far as I know, at least in some cases, like "Set direction".
  14. Hair inside mesh

    If guides are ok and not getting into the mesh than its probable hairs side. For example, Gude Proces (Frizz) may cause such a thing, so you may decrease the influence of such nodes at the root o the hairs.
  15. HDA Derivatives - Workflow Question

    Understood about SKU! Actually, I work in the automotive industry and do exactly what you describe as an example . We call it configurable products. We treat each vehicle as one asset no matter how many configurations it might have. That makes a total number of assets more manageable. And at the high level, we do like your describe, populate each SKU on demand.
