  1. I'm at the end of my rope and nearly out of hair to pull out over this issue. I'm trying to render out an animation for a client and I've followed Chaosgroup's suggestions for rendering scenes with moving objects and cached my Irradiance Map, I've found forum posts about using Brute Force instead and tried that, I've adjusted the subdivs of my reflection up and down and gone to Oz and back, but I'm still getting flickering in the reflections from frame to frame. Does anyone know what causes this or if there's an easy fix? It's only happening in my specular and reflection channels, so I'm doubting it's a GI issue and more a material/VRay settings one, but I'm out of ideas. Here's a link to a .gif I threw together where it's happening: http://imgur.com/a/l8fks
  2. Hi guys, i think that when we are speaking about animation with Vray, there's so much confusion and misunderstandings through the web. The workflow seems so different for each "teacher", both in the forums, youtube, vimeo. Usually the threads/video are a little out of date and you wonder if Vlado invented some new tricks to speed up animations and quality. Chaos Group guide let everybody understand which is the problem with animations, how GI works etc etc. But most of the time this is not sufficient to free your frames from the evil bounds of flickering. By the way, Youtube and Vimeo are full of outstanding flickering free Archviz Animation made with 3DS + Vray. So I write this post with the ambition to help myself and others castaways to understand if there's a basic workflow for animations, by sharing yours. It would be really really nice and useful if each one of you could post: 1) an animation/link made with 3DS+Vray 2) settings for the prepasses and final animation. 3) resolution and (if possible) the time for each frame 4) (less important but why not) If you rented a render farm and the cost of the entire animation. I know that there are different workflows if you have a moving camera with still objects, or both moving or fixed camera with moving object. It's not important, just share your workflow based on these type of animation. I know it may sound pretentious and there are plenty of possibilities that i'm wasting my time writing this. I hope not, because really there isn't so much informations about animation settings and this forum is full of skilled CG Architects. Shall we prepass Light Cache or Directly the Irradiance Map? Is it important to check "Don't Render the FInal image" on Global Settings during prepasses? Does the noise threshold affect flickering together with GI? Does light/reflections subdivisions affect flickering together with GI? Too much questions and sometimes you don't have the time to wait to see differences unchecking or not an option, especially if you work alone. I hope to read soon yours experiences and workflows. For the people who are starting now with animations, check this link to the Chaos Group Guide, really useful, but doing what they say, i didn't get optimal results. http://docs.chaosgroup.com/display/VRAY3/Rendering+an+Animation+with+Moving+Objects+II Thanks!
  3. Hello, Im having problems with flickering in trees. Attached are my settings, and here is the video: https://www.mediafire.com/?479cijrqzs2e2sc The filtering for bitmaps of leaves are set to none. Units: meters/meters. Avg. task time: 4:04 on 3770k. (Quarter of image, only trees, the whole frame with all elements should be 25/30 min) 3ds max 2012 x64, Vray 2.30. Also i have tried with IRR Medium 50/25, and the DMC image Sampler in 1/16, with the same results... What need to change to avoid flickering? (at reasonable rendering times) Thanks in advance!
  4. Hello, I know there are a lot of threads about this but I decided to start a new one because everything in my scene looks fine except for the flickering. From quality to render time per frame it all is acceptable. 1. Setup AA and sampler settings. Never changed them all through. 2. Precalculated LC in both 1st and 2nd engines in fly-through mode. 3. Precalculated IRMap with previous LC animation prepass 4. Rendered with previous IRMap and LC in animation rendering.

  5. Hi all. I'm just trying to create a basic walk-through of an interior with 3ds Max and V-Ray and I'm having all sorts of problems with flickering reflections. I've posted an example movie on youtube: http://www.youtube.com/watch?v=QQdjOgLyqRA&feature=g-upl&context=G25b953cAUAAAAAAAAAA My settings can be seen here: http://imaginethis3d.com.au/wp-content/uploads/2012/01/vray-settings.jpg http://imaginethis3d.com.au/wp-content/uploads/2012/01/glossy-materials.jpg The problem is particularly visible in the glass beside the staircase and in the glossy black kitchen cupboards. Any suggestions would be much appreciated.
  6. Could someone tell me why the fine lines in this video flickers. I think its the AA but I've tried everything...well almost. I recently tried Detail Enhancement and that didnt work. Here are my settings Adaptive DMC AREA 1.5 Reinhard Subpixel Mapping checked Affect Background checked Adaptive Image Sampler: Min 1 Max100 Clr thresh .005 Use DMC sampler thresh unchecked Animation prepass then Animation render with Irradiance Map and Light cache following the directions here http://www.spot3d.com/vray/help/150SP1/tutorials_anim2.htm Irradiance map: min -3 max 0 Hsph subdivs 50 Interp samples 20 Clr thresh .2 Nrm thresh .2 Dist Thresh .9 Use camera path checked Light cache: subdivs: 2000 Sample size .02 Scale: screen (I tried world but I kept running out of ram) Filter: Nearest use camera path checked Interp Samples: 5 DMC Sampler: Adaptive amount .85 Noise Threshold: .001 Min Samples 20 Global subdivs multiplier 1.0 video here:
