  1. Very slow redshift render

    Thanks a lot Flcc and Atom. I'll definitely dig deeper in the sampling documentation.
  2. I am new to Redshift. For a very basic scene with three objects, at a resolution of 1280x720, it took 13 minutes to render. I have intel core-i7-8750H, Nvidia GTX1050ti -4GB and 16GB of RAM. This is the output. I have rendered more complex scenes in Keyshot at a resolution of 1350x1350 and it takes 6 minutes max for them on my machine. Please suggest a solution. Here's the houdini file.

  3. Very slow redshift render

    Actually I posted there too. A maxon employee is saying that my hardware is not compatible which I find bit weird. All the requirements are being fulfilled by my hardware except the VRAM is 4GB instead of GB. https://redshift.maxon.net/topic/39413/very-slow-and-noisy-render-with-very-less-geometry/11 If other rendering engines like V-Ray, Twinmotion, Keyshot and Lumion are compatible with my machine, how can Redshift be incompatible?
  4. Very slow redshift render

    Awesome! Thank you so much! It took 43 seconds now! You're talking about these sampling settings right? You changed only these or something else too? I did another render using the same file as yours and turned on the Optix denoiser. It got rendered in 1 min 18 secs.! How to decide whether Optix should be used or samples should be increased? By trial and error?
  5. Very slow redshift render

    Yeah. It's very frustrating to see this. Later on I enabled Altus denoiser dual pass and the render took freaking more than 1 hour to render. Here are the denoising settings. Here's the Hip file. redshift-issue_1hour-render.hip The hardware that I'm using is already mentioned in the original post. Houdini is installed on Samsung Evo 970 NVMe SSD. It has 30Gb free out of 231 GB. I'm using the latest studio driver for my graphics card. My windows is up to date.
  6. I am using version 2.6.41 of redshift. How can I add multiple camera angles in Redshift and batch render them all at once?
  7. Batch render in redshift?

    Okay I can understand making multiple RS Rops and assign them to different cameras and wiring them into a merge. Can you please share a screenshot for setting it to node by node?
  8. I don't know what setting I have accidentally toggled. I am able to make a sphere in Houdini but box and platonic solids aren't showing up. Even when I start a new file. What should I do? I made this video recording 2021-10-13 22-57-14.mkv geometry issue.hip
  9. I am trying to remove portions from a geometry which are not connected to it. I am using vdbsegment by connectivity. But it is giving me an error. It says 'no vdb grids to process' . What should I do to overcome this issue? vdb segmentation problem.hip
  10. I am new to redshift. I am using version 2.6.41. If I render the scene with just a sphere and donut, it renders out fine. Despite using a number of samples, I am getting noise on the ground when I have the organic blue volume. Here is the .obj file which is used in the scene. https://www101.zippyshare.com/v/THie8eoD/file.html Here's the hip file. RS_RENDER QUERY.hip What should I do to reduce noise? The render time is quite high too at 8 minutes. I rendered similar geometry (the blue organic geometry is same, only the sphere and torus are different) in Keyshot but the render time is very less. I tried with 100 samples, 200 samples and 500 samples.
  11. Reducing noise in Redshift?

    Okay. I'll experiment more with dome lights and increasing material samples. What exactly is a reflexion?
  12. In Grasshopper for Rhino, one can set up the alogrithm to select objects based upon their proximity to a single object. See the video. Here is the Hip file in which I arrayed the geometry. selection question.hip
  13. I converted chose VDB in the 'Convert to' drop down menu and the volume disappears totally. If I connect the volume vop output to vdb segment by connectivity, then it's also blank. vdb segmentation problem.hip
  14. Thank you so much! How did you record this gif animation?

  16. Reducing noise in Redshift?

    So what is your workaround for reducing/eliminating noise in renders? I'm getting noise in a scene that just contains 3 objects and only two plain textures. I'm unable to figure out how things will go when I will have more objects in my scene.
  17. Reducing noise in Redshift?

    Okay. Thanks. Yes. Sometimes the yellow progress bar shows up, sometimes it doesn't. I don't know why. Another question. I was wondering why you setup redshift in c4d for all your scenes. Is setting up Redshift in Cinema 4D better than in Houdini?
  18. I don't understand. How do I use it? I don't know VEX at all.
  19. Reducing noise in Redshift?

    Thanks a lot. Sharing what I'm experiencing. This one rendered in 1 minute 5 seconds without denoiser turned on . This one rendered in 1m 34 seconds with Optix denoiser turned on. While there is considerably less noise on the ground plane, the noise on the blue surface increases significantly. I am unable to find this setting. Where is it? Moreover, is there any way to see a progress/percentage based timer going on while the render is happening like the one seen in Keyshot at the bottom right? Also, when I opened your file, I got this error. Why is that?
  20. I don't understand. How do I do it?
  21. Reducing noise in Redshift?

    Thanks for taking a look. I have intel i7-8750H processor, Nvidia 1050Ti GTX 4GB graphics, 16GB RAM. This is weirder than expected. How much samples are you using in C4D ?
  22. Separating objects by colour

    Thanks a lot for sharing this. Will definitely check it out!
