  1. Velocity Blur not working with Arnold in Solaris

    Arnold needs the scene to be cached just like Karma does, in that video - yea it's a p.i.t.a. Maybe some drawback of usd? Dying to know why we need to do an additional cache just to get mb now. My scene takes 20min. to cook just to open it.
  2. Velocity Blur not working with Arnold in Solaris

    Do the points actually have a velocity attribute on them - it's not automatic
  3. Weird lighting interaction

    I haven't modeled for years and it could be that normals/smoothing is better now - ? But edges with no bevels like you have here, was always just begging for trouble -
  4. Too early for 3rd renderer? (Prob. Redshift)

    10hrs to render 96 frames is only @6min. per frame - animations always take a long time - I'm pretty sure fx animators mostly rely on openGL rendering. It's up to you really, if you want to learn both particle fx, and rendering, there's nothing wrong with that, it just might be a little slower to learn
  5. sounds like more trouble 'plus' less flexibility than just comping it
  6. Switch material based on ROP per Object

    We generally just duplicate the object ( or objmerge it into another geo node ), put a different shader on it and use that in the other rop. I suppose you could also set two different OUT nodes in each rop, but I've never bothered
  7. Rendering shows up Nothing

  8. Blur sunlight reflection

    Try increasing the "Sun angle" under Distant Light options But I think it's going to look strange with some things reflecting blurry and some things not - You could also use a different light or object to reflect / specular, instead of the sun light.
  9. Anamorphic projection problem

    Not sure how you'd do that ( I'd guess that baking a sequence would work, and projecting uvs from the camera might be useful ) but I can't for the life of me figure out why you'd want to do step 4. If you flatten the screen in any dimension other than the camera's perspective, it breaks the illusion / doesn't fit the projection anymore ; if you do flatten it in the camera's perspective, then it's the same thing as a perspective render.
  10. You've got mega-tons of textures, I'm not surprised. Have you ever tried opening all those 4, 8 and 16k maps in one app ( you can't judge by the file size either, unless they're completely uncompressed files )? Mantra converts them into .rat for rendering too ; if you do that ahead of time, it should help. https://www.sidefx.com/docs/houdini/shade/convert.html .rat files are tiled but if you don't specify the specs to your needs, it won't be optimum
  11. * why can't I delete my posts?
  12. Rendering destroying my mental health

    I was going to test your scene ( my 'puter is weaker than yours and I've had no such stability problems ; mac from 2010 w/22gb ) but the links are gone - have you been watching the ram? A big part of working with dynamics is knowing how to optimize them, much moreso than in other disciplines.
  13. Volume lighting AOV issue

    It kinda does make sense - they're 2 different renderers! They're even different types, cpu & gpu. Unless redshift works in the renderview? And lights hitting the smoke and showing up in the volume lighting aov - is really what it's supposed to do, isn't it?
  14. I can't see object by Mantra Rendering

    Your switch node is switching the input to a null on frame 2, because of the expression "$FF>1".
  15. render motion blur in Arnold

    I forget what the fx guys do for that, but I do believe you have to make sure and use the same number of time samples / motion steps ( they all have different names for it ) in both Houdini and Maya. Actually that might be all you need -
