  1. Interesting, I'll try it... Thanks
  2. Like I said, you won't get it with a dome light. I had a long email conversation recently with chaos group support with this exact problem and they told me that at the moment dome light environments are not supported with wrappermtl. They are working on fixing the issue. Regards
  3. Backgrounds in a dome light are not supported. Use the environment background method in vray options environment tab. Also in the Wrapper Mtl you will need to tick the check boxes for "Matte", "Shadows", and "Affect alpha" -- then set the "Alpha contribution" to "-1"
  4. Hi, I'm using vray for Rhino but it probably doesn't matter what the vray platform is. I have a scene with an environment background image set in the Environment background slot of the option editor tab. The model renders and displays fine in the VFB. But whenever I save as png, I get a transparent bacground instead of the background image. If I save as jpg, the image is complete. Where the heck did the background go ? I like the png format but in this case I don't want transparency. I don't see a choice for that. If I use a dome light instead and place the environment image there, I have no problem saving as png. But if I use the environment background option I get this problem. What am I missing ?
  5. Yeah, I was gonna write you when I saw your message ... I'll go with the first one. I have a Corsair AX650 in my main workstation and I'm very happy with the noise level. It's so quiet ... I'm almost ready to order. BTW I'm still curious about having a cheap 1366 Xeon configuration around $600 as you mentioned earlier. Do you have a recent one that you might have posted ? Thanks
  6. Hi Nikolaos, Thanks again. I'm looking into ordering something very close to your proposed system. I managed to get price matches etc and get everything in one place (NCX). The only item they don't have is the Cooler Master VSM 550W 80+ Gold Certified Semi-Modular ATX Power Supply. Can you give me an alternative that NCX would carry? They will match prices anyway. I want them to assemble the system for me so I rather don't get it elsewhere, better if they have something equally good even if it's a bit more money.
  7. Boy, that was quick ... Is it enough going to Bios and lower the frequency and voltage ? I was under the impression that the 4 way optimization tweaks a whole bunch of other settings ... Regarding the sample system configuration that you suggested earlier, I see that you picked the i7-5820k over the i7-4790k despite the increased cost, power consumption, and more expensive memory, board and needed GPU ? Do you feel that it's worth the extra cost for the increased performance in rendering ?
  8. Hi Nikolaos, Thanks for your detailed reply. Since I wrote the post, I had already made changes to my overclocking based in other videos and postings from Asus. I ran 4 way optimization software and it's now running at 4.5 GHz / 1.255V at 72-78 degrees under full load (rendering an animation with vray in Rhino for 3 hours now). I thought that temperatures for the 4550K could go higher but thanks for the tip). The frequency and voltage fluctuates much lower when idle. (35-40 deg) Also, in the meantime I found a used system in Craiglist for US$580 that could be also a cheap option. MB: MSI P67A GD65 Ram: 8 GB Crucial ballistix sport CPU: Intel Core i5 3570k 3.8 GHz CPU Cooler: Cooler Master Hyper 212 Plus Graphics Card: HIS Radeon HD 6970 2 GB Seagate: 1 TB hard-drive Crusial BX100 120 GB SSD I had asked Dimitris on his blog but I've got no reply yet: http://pcfoo.com/2014/03/2014-the-less-than-600-render-node-early-2014/#comment-3686 What do you think ?
  9. Hi, I use Rhino and vray as my main tools for modelling / rendering. I have a relatively new main workstation and a small farm consisting on a Asus G73 laptop and another 2 less powerful desktops that I had around. However my laptop died (motherboard is gone) and I'm looking for an extra system to replace it. My main workstation right now: Intel I7 4770K o'clocked at 4.6 Mhz and very stable MB Asus Z87M-PLUS 32 GB Ram NVIDIA GeForce GTX 770 4GB SSD 256GB + 3TB HD Corsair CMPSU-650AX 650W Gold AX PSU Cooler Master Hyper 212 EVO CPU Cooler New machine budget $1,500 tops My thoughts: 1.- Getting another laptop as fast as possible to replace the dead one so that I can also use it as my portable station when I need to (not very often but always useful to have the option if I travel) or ..... 2.- Build a rig faster than my current one listed above to be used as the main station using the good video card and big hard drives from my current workstation. I'm interested mainly in the processor power and the 4770K still is a great processor as rendering slave and a small hard drive and a cheap or even on-board video card will do. I know that for the same money a desktop buys me more power so maybe I should forget the laptop option for the times I'll be needing to have something portable ... I any case, what would be the best $/GHz rendering rig that $1500 can buy me, i7? Xeon ? single? Dual ? taking in account that I could use some of the components as I mention above. I get easily lost with so many opinions ... Thanks
  10. In Rhino you can 'hide' objects or turn off layers, or a combination of both. After doing more testing I should correct my previous posts by saying that the problem seems to be only when hiding objects where Vray still considered them as geometry in the scene, whereas turning off layers actually does the expected effect by vray not considering them as geometry. I'm inclined to believe that it is a problem with the way that vray treats hidden objects. I've tried with a another two render engines and they respond properly to hidden objects with shorter wait time like one would expect.
  11. Francisco, Everything that you say is true and I'm well aware of that. RAM is not an issue, I have 32GB and looking at the task manager I still have 65% of RAM free. The model is relatively large but nothing out of the ordinary. You are absolutely right that objects off camera still might cast shadows or contribute to reflections. The reason that I was posting this is because, as I explained earlier, even leaving only one small object and freezing/hiding layers for the rest, still gives me exactly the same delay. That's why my first question was whether vray ignores the fact that the layers or objects are off and it calculates all the geometry anyways which doen't make sense and I refused to believe unless there was something that I was missing... Well, guess what ? I did some tests today and If I deleted everything in the scene and leave that single object as opposed to hiding or turning off layers and there is no delay, like I would expect. So I have to conclude that either Rhino or Vray don't care if you freeze layers or hide objects and still considers ALL THE GEOMETRY in the pre-rendering stage regardless of being visible or not. Why on earth would vray need to collect geometry that is turned off and for all purposes it doesn't exist ! I look forward to a logical explanation ... Thanks for your input anyway
  12. What does vray do exactly from the time that I hit 'render' to the moment where the frame buffer and status window show activity ? I have a scene in Rhino where, regardless of what vray settings I use (low or high quality), it always takes a long time to start the pre-passes. I tried turning off-the-camera objects but it doesn't seem to make any difference. I also happens with GI off. However, when exporting only the objects seen by camera and rendering them as separate scene the process starts way faster. This suggests to me that vray still considers the objects not seen' by the camera by turning off layers or by hiding the objects individually. Thoughts ? EDIT: I tried leaving ONLY one object vs. ALL objets (some 1,200 objects, file size is 30mb) and takes exactly the same time, about 4 minutes to see any activity. Also the framebuffer time stamp doesn't take this wait time into account ... And by the way all vray windows become frozen so I cannot cancel. Is this normal ?
  13. Hi, I'm long overdue for a new rig for my 3d work. I'm currently working with an Asus G73 Laptop and want to move to a desktop workstation since my mobility is not required anymore and my models keep getting more demanding in size and rendering requirements I model in Rhino, render in Vray 2.0 for Rhino. Vray-RT top performance is not an absolute must but welcome, of course. I use also Cinema4D mostly for animation and complex ocean water systems, foam and ship wakes since my specialty is ship design. Occasionally I do some video editing in Premiere but not with huge projects. I've been browsing through forums such as this one and tom's hardware, and I came across this recent thread which I feel matches somehow my needs: http://forums.cgarchitect.com/75345-some-advice-new-workstation-appreciated-3.html However, my budget is somewhat lower, around US$1800-$2000 (~CAD$2200) I quoted the list in post #23 from Newegg canada at around US$2300). What Items do you feel that I could downgrade to trim about $500 (as I will have to pay shipping and taxes on top ... ) and still have a nice solid system? For example, I'm wondering whether I need 32Gb of RAM. I have now 8Gb and I have not ran out of memory even with my large models (120Mb, 1.5M polygons), and looking at the resources monitor, there is always memory left even when rendering reaching maybe 85-90% of physical mem (which of course includes windows tasks and whatever else I have open). Just wondering if more memory would necessarily improve performance if I'm not paging to disk yet. Would 16Gb would suffice? That alone would save $200. Your help is really appreciated !
