  1. Please post a file or at least a snapshot of your shading network. There can be dozens of causes for your problem.
  2. Epic Games Invests in SideFX

    This is the first step to forging Alliances. It may be a way to avoid falling, in the future and in case of a hard blow, into the lap of autodesk or adobe. My two cents opinion
  3. Even if this is not quite true, it can be considered that the more flexible the engine is, the less easy it is to use. It all depends on what you want. Ease, speed, flexibility? If you are looking for an easy and fast renderer go to Octane. If you are looking for a powerful and flexible renderer go to renderman. (don't know about Karma yet). Between the two you can choose Arnold or redshift. The advantage of redshift is its speed, which does not require a lot of optimization work.
  4. Workstation out of the box?

    Depending on where you are there is an intermediate solution. Find a reseller specialized in 3D production. In France there is APY that I know. They mainly provide 3D production studios including "Illumination-MAcGuff" (despicable me). They have an online store, but it's better to call them to customize your station. And when you talk to them on the phone, you can see right away that they know what they're talking about. And since they are in contact with the studios, they are aware of possible hardware compatibility problems, especially for the big GPU configurations. Their prices are fair. They now have a branch in Canada (don't know them). Not a build yourself, but better than out of the box solution IMO.
  5. Not sure it's what you want. May be a clue. Vary_Bend F.hip
  6. Redshift DSO Error

    Due to the numerous updates of Houdini, depending on the version of redshift, support is dropped for older builds of houdini versions. It is strongly recommended to use the latest version of production build. 17.5.460 for 17.5 You can find the list of compatibility in the read me of the redshift install folder, or on the redshift site
  7. Easy way to animate material hue?

    Not sure what is the problem as you can keyframing almost everything in rs vopnets. In volume you can act on tint. On standard materials you an use rsColorCorrection to act on hue. RS hue.hiplc
  8. Paint splash via heightfields?

    Wow these videos by future Deluxe are mind blowing ! May be some ideas in this asset (not heighfield) https://www.youtube.com/watch?v=zTLc61HxIwU
  9. Procedural, little low poly Village

    You should also be able to erase the houses that are totally surrounded by each other, i.e. they have no access to a "street". Nice work, by the way.
  10. Tiling redshift ramp

    For the tilling of the number texture you better to use the remap area of the rsTextureSampler. And also using the rsColorLayer is more straightforward. rs tilling.hipnc
  11. Houdini 19 Wishlist

    And a non-linear animation systeme like Maya trax or C4d Motion mode or 3DSMax... I know it can be done with chops, but compared to a dedicated system, it's a pain.
  12. And in your example, as distance between original points and displaced point is much greater than neighbour points distance, you also need to use source and destination groups.
  13. random rotate top face of polygon?

    Many solution here @eikonoklastes, @dleonhardt nice tricks @petz Don' really understand how it works. Not a rotation, a projection ? could you explain a bit ?
  14. VEX for artists

    A nice non video Vex tutotrial, that deserves a praise.
  15. random rotate top face of polygon?

    I think boolean solution is a better option, because the rotation forces a tightening on the top facet. columns01_F.hip
  16. random rotate top face of polygon?

    For the random angles on the tops, in a for loop you can boolean substract randomly oriented cubes. For the gradient, before your copy to point make a more or less random @scale.y attribute from Z that you define in a wrangle. Or with the same wrangle add a transform in the for loop and use the scale.y attribute in the scale Y field.
  17. too slow redshift rendering

    isn't redshift a GPU renderer ? Make sens to have a low CPU usage.
  18. Redshift compatibility

    You can find these informations in release_note.txt in the redshift folder (C://appdata/redshift). But no you can't use a build for H17 with H18. And due to the frequent build of houdini, support for old redshift version are quickly dropped. Non supported version can work or not.
  19. redshift ambient occlusion

    Just plug an ambient occlusion texture in diffuse Weight or where you want.
  20. Simple Tree Tools

    Excellent ! Thank for the video, I downloaded it some time ago, but now I'm going to try it out immediatly True that Simple tree may not be the best way to describe this tool anymore !
  21. Bullet and Constraints learning ressources?

    It is true that it is not easy to find some on this particular subject. I had looked at this one. Not too bad even though it's in Turkish. https://www.youtube.com/watch?v=1_8aGjSnigU [edit] Just see your link. Interesting too.
  22. You can Always get the redshift demo to learn a bit and see if it can fit your FX needs. The demo is fully functional. Just renders with a watermark.
  23. Noise type value visualization

    I've done a snippet like this... but with a menu it's better thanks
  24. On the redshift forum, Tortoise ( I think it's here also ) post an houdini asset who do the stuff very nicely( but for redshift obviously). Sort of stochasting thing thing. https://www.redshift3d.com/forums/viewthread/31947/
  25. volume position

    That's a good point, actually, this setup just return P ! But why make it simple when you can make it complicated ?
