  1. @John, Followed your input and the first test results are pretty oke. Love it when things make life easier. As you can see i tried out the units variation and different placing of the light source ( sphere ) to see the effect. Also believe that the intensity multiplier effects how good you can see the bloom and glare effect, guess that is situation depended. Did tryout an extruded square and circle but doesn't make it compared to the sphere. Still wondering what you mean with a " simple point source ". Cheers,
  2. Hi everybody, Breaking my head on trying to mimic one of those christmas led's. Did test's like different materials / ior / ies lights....but just don't seem to get it ? Starting to feel like a floating cork on open water, please someone.... give me some guidance to the coast !! What i did : 1. Finding out the real world setup of how a led is made. 2. Putting the IES light on different levels in my led ( to see the effect on various angles ) 3. Making a reflection cap around my IES light and inside the led. Result was minimal, so left that out. 4. Making a second refraction layer to my epoxy material ( ior 1.438 + ior 1.627 ) Trying to make a sort of lens effect. This made some effect as expected. So left that in. What am i missing, doing wrong ? How would you make it ?
  3. Hi Folks, For those wondering, made sort of an improvement by using a Vray 2sided Mtl. Materials try out; 4. Vray2Sided ; front : Mtl 1. back : Mtl 3. Sort of liked the results of material 1 & 3, so combined them with the 2Sided Mtl. Leaves toggeling around for adjustments to preferences.
  4. Trying to fabricate a translucent plastic caseholder for a fuji film roll. Inside is a Christmas led light ( IES ). Materials try out; 1. VrayBRDF ; Glass_Coated ; adjustment color white - IOR 1.5 2. VrayBRDFSSS2 ; Plastic_SSS_02 ; adjustment color white – IOR 1.456 3. VrayBRDF ; Plastic_Transucent_01_white ; adjustmment color white - Opacity 0.8 4. Layer Material ; Reflection / Diffuse and Refraction layers 1 & 3 look the most like the original. But it's still not there, room for improvement ! How would you approach this ?
  5. @ Ernest, Adding to the conslusion: C: Toggle around with the IOR ( 20-30 ) for more realistic mirror effects ( the imperfect surface / mirror ) " the glare effect "
  6. @ Nicolai, Thanks you method 5 works good. Result is like method 1,2&4. For the setup my diffuse color was red ( 255,0,0 ) What I don't understand; Method 3 uses by default the natural fresnel effect on materials ( texfresnel ) and a IOR of 1,55. Boosting the IOR ( fresnel index ) up to 50, you would expect total reflection, preview texture editor ( white / gray ), but a red glare remains ? 1. preview texture editor ( black ) - diffuse color red ( 255,0,0 ) - result ; good mirror 2. preview texture editor ( white / gray ) - diffuse color red ( 255,0,0 ) - result ; good mirror 3. preview texture editor ( white / gray ) - diffuse color red ( 255,0,0 ) - result ; red glare on the mirror 4. preview texture editor ( black ) - diffuse color red ( 255,0,0 ) - result ; good mirror 5. preview texture editor ( black ) - diffuse color red ( 0,0,0 ) - result ; good mirror My conslusion is tor the perfect mirror ; A : Don't tamper in reflection ; texture editor ; IOR, let it by default 1,55. B : Only change in reflection ; texfresnel to none or parallel to white and diffuse color doesn't matter !
  7. Only changed the default setting in refelctions ; 1. texture editor - default bitmap texfresnel replaced by none 2. texture editor - parralel color to white ( 255 ) 3. texture editor - IOR 1,55 set to 50 4. general reflection - 1,0 set to 50 5. other method ?? Test setup ; method 1,2 & 4 gives good mirror results. Method 4 has a red ( 255 ) glare. I,m confused, because this is a method a lot of tutorials recommend. ( https://www.youtube.com/watch?v=PvfhfYz2QWc ) Which method would you use and why ?
  8. @ Dimitris Took a look at you recommendations, really helpfull. I think my single GPU must be adequate to do the job for now ( vray / su / cad ). Therefore i'm not planning to go for a 2nd GPU for an other estimated 2/3 years, as i'm just on the start of things. In practice i also don't see my self doing extreme overclocks. Taken these notes and your recommendations on the PSU the obvious thing to do is to swop the Be Quit L8 630w 80+ Bronze ( € 80 ) for a Cooler Master VS-Series 550w 80+ Gold ( € 81 ). The 92% efficienty and ripple 50-500w under the 13 mVtt are nice, as far as they are no sales pitches. When the wishes are necessary i will go for the PSU and GPU upgrade. You're right that energy consumption of HDD, probably 2W vs monitor 62W is a no brainer. Therefore I was thinking of hooking my monitor on my solar panel, because now it is hooked up on my treadmill. LOL. You see, I love multitasking, combining work and exercise. Yes, you quessed correct that RAID 1 the pair is the idea. Taken your comment on backing up data externaly, I'm thinking to go for 1 x 2TB HDD and backup on my current external WD 2 TB. This will save me € 145 and forget about the future NAS, and just wait for SDD TB to become cheaper for the next 2/3 years. Then upgrade my data capacity with SDD. This also forces me now to keep only the necessary.
  9. Thanks for all your inputs thus far. Doing some reading up I gave my self the luxury to expand my budget and think I've got my specs clear ( tot. € 1600 ). Of course with less, the job will also be done. CPU : i7-4770 K + Cooler master 412 s Mobo : Asus Z87-pro Ram : G.Skill Ares 16 GB ( 2x8 ) 1600 / 1866 ( less high, better fit with the CM 412 s ) GPU : MSI GTX 770 4GB ( monitor Eizo EV 2736 wfs / res. 2560x1440 ) SDD : Samsung PRO 256 GB HDD : 2 x 3TB WD Red ( 5400 - variable rpm ) / Seagate Barracuda ( 7200 rpm ) PSU : Be Quit L8 - 630W ( benchmarks ripple 200-600W all under the 50 mVtt ) OD : Asus DRW - 24 B1ST Case : Fractal Design R4 There are just some things I'm still wondering about ?! 1. Is the PSU 630w sufficient enough ? Possible future expansion of 2 x GPU 2. Like the HDD WD RED's due to low energy consumption and possible use for later expansion for NAS. What are you thoughts ?
  10. @ Andrew Lynn, Being new on this forum i've posted my answer to Juraj twice, both in a little different manner, being under the impression that something when wrong with replying. Thanks for still posting my reply's. No, I haven't got any experience with Vray RT GPU so far. Want to upgrade to Vray 2.0 for SU. I believe the viewport render will give me a lot of benfit, due to its direct feedback, and want to take that possibility to the max. So production render will still be CPU based and " workflow " render GPU based. I was under the impression that Vray RT was only working on the CUDA architecture for vieuwport render. Seeing the promo clip again ( ) I'm wondering : 1. Take the CPU : i7-4770(K) / Xeon E3 1230 V3 + GTX 670/770 4 GB ( max GPU viewport render, direct feedback for settings ) Also like to have my monitor at high resolutions. Or should I save € 250/350 on the GPU and go for the high-end CPU; 2. Take the CPU : i7-4930K / i7-3930K + low end GPU ( frame buffer wil work slower, due to CPU multitasking Adobe CS 4-6 ?? ) @ Dimitris, Thanks again for your constructive input, really appreciate your advice. Cheers
  11. @ Dimitris, Due to Juraj tip, I'v visited you site / blog. Compliments on the constructive and clear elaborations on possible configurations, that’s a talent !! I’m new to the world of DIY pc systems and getting more and more hooked on the virus called visualization. I work with Autocad 2010-14 / Sketchup 2013 + Vray ( RT ) / Adobe PS – Illustrator – Indesign. In de near future Revit / 3ds max / Vectorworks will be tackeld. I’d like to take full potential of Vray RT, because I think this can save me alot of time due to it’s direct feedback aspose to setting up / render / reset / render etc, etc. I thought I’d made up my mind with the following setup; Budget : € 1.300 ( inside components ) CPU : i7-4770k ( i7-4930k, think this is an overkill for my first overclock CPU ) Mobo : Asus Z87 Pro ( like the Btooth + Wifi ) GPU : MSI Geforce GTX 760 2Gb ( Vray RT ) Q 1 ; Roaming the net I get the impression that Intel CPU’s set the pace for Render workstations. You also point out the AMD FX-8350 as a CPU to take into account. I’m puzzeld and seems like a toss. But that’s of cource not the way to go. Could you point out, with my needs above, which one cuts the edge and why (or even another one, just to make me puzzel more.. haha ) ? Q 2 ; Will the GTX 760 2GB be adequatly enough for my purpose with Vray RT? Or go for the 4GB version at + €100. Cheers
  12. @ Juraj, Thanks for the respons. Thought i made my decision on a i7-4770k (6c / 4th). Now the AMD FX 8350 ( 8c / 8th) pops up. Checked out Dtolios blog, wow he knows his stuff, really helpfull. He even mentioned this; "Note that despite the clear victory of Intel’s CPUs in single threaded applications, the FX-8350 remains competitive and even surpasses the Quad core i7s in pure VRay and Mental Ray performance ". Using Vray RT in SU I'm now leaning towards the AMD, comming with a friendly price !! Seen alot of configurations where intel takse a prominant position. Are intel that much better in 3d modelling and rendering over AMD, and why ? @ Benjamin, Why is the AMD FX-8350 not better for you than the i7 ?
  13. @ Juraj, I have been looking into the i7-4930k ( 6 cores / 12 treads ) vs the i7-4770k ( 4 cores / 8 treads ). The i7-4930k has a theoritical 35% higher cinebench 11.5 than the latter if i must believe the benchmarks. Believe the cinebench 11.5 is the render speed !?? Still don't really understand where rendering takes its advantage in the CPU, the extra cores or the treads ??? Don't I limit myself with the 2011 socket for the i7-4930k for possible future upgrades ?? The i7-4930k also comes at + € 230 over the i7-4770k. My puzzler is ; What ever CPU it will be, its going to be my first overclock CPU. Just think its a lot of money for the first time around, possibilties for mistakes are high, warrenties, etc, but of course that's the dive i'm taking. Think both CPU are great, one faster than the other, but at this moment think that I'll have to take the i7-4770k to it's full potential, getting my setting right in Vray RT and than hit render for the night. Also got a tip for the possibility on a Dual CPU setup 2x Xeon. Get the impression that it isn't used that much. Well, now know that the price is the show stopper and your talking major league. Besides the price, isn't a Dual CPU depended of a lot of different features to really get it's full potential of such a setup ? Yes, really believe that Vray RT can save me a lot of time due to the direct feedback vs setting up / test render / setting up again, etc etc. Nice to know that i'm on the right track with the GTX 760. Please correct me if i'm wrong, but believe i read somewhere that the 4GB version ( + € 100 ) is acctually a 2x2GB and therefore in practice only 2Gb, that would be money bad spend !! If i understand u well, I could do less than 750W, just take a lower PSU with gold standard ?? I'll lookup the Quadro vs GTX discussions. As far as I understand the Quadro is strong in building your 3D scene and swiffeling around. Future aspirations for Revit /3Ds max / BIM modeling will probably corner me to Quadro cards. Was thinking for a Samsung 840 Pro-256 GB. Install Win 7/8 + applications and a copy of current working projects. See a lot of recommandations for this setup, seems the way to go ! 2x 3TB HDD, 1x3TB for files and the other 3TB for backup. @ Benjamin, Thanks for the surge spikes issue. Is this due to a cheap PSU ! You work with a NAS als backup ?? Wondering if putting a WD red, advocated as a special HDD for NAS wil also be suited for a desktop ?? Im thinking why not ?
  14. Thanks Juraj, I'm mostly in for a strong CPU. I have been checking the i7-4930K vs i7-4770K. I just wonder if the extra + € 230 for the i7-4930k isn't a overkill, though cinebench 11.5 i7-4930 k = 10,93 vs 8,08 of the i7-4770k. I also wonder if the S 2011 won't limit me to much in possible future expansions ? I was also hinted to look at a Dual CPU 2x Xeon. I get the impression that not a lot of people use them, but a the start of € 5000 I understand why, we are talking pro's. I'll be happy with less for a beginner. Isn't it also, correct me if i'm wrong, that to get the full potntial out of a Dual CPU setup, als things have to work well. I mean the chance thing are not working optimal is bigger. Yes, I really believe Vray RT can save me alot of time. Nice to hear that i'm on the right track consering Vray RT. The GTX 760 4Gb is + €100 vs the 2GB version. I believe I read somewhere that the 4GB will not give you full provit over the 2GB. If true, that would make money bad spend. Better to put it in a CPU or mobo. Believe i read something about 2x GPU voor Vray RT, for better overal performance. Is this true and if so, how ?? Understand kan I could do less than 750W, just look at less with a gold standaard ? I was planning to go for a Samsung 840 Pro - 256 GB. Put my Win 7/8 on it with my applications ( Lot of recommandations for this on the net ). And put my current/working project on there on temporary basis. Beside this also 2x 2TB HDD. One for files / other for backup. Question is it wise to go for the i7-4930K ? Reading the benchmarks it will be theoretical 35% faster than the i7-4770K. That is alot. It's also alot extra cash. Also this being my first overclock CPU, ****ups, warranties etc., but that's the dive i'm in for. In practise I render before night and ready in the morning. Therefore I need stability. At the moment i think i7-4770k wil also do the job, probally push its limits a bit more and also a good excuse to get yet another cup of coffee. But i still really fansy the i7-4930k.
  15. Thanks for the PSU advice, i'll have to look into that aswell. Isn't Hyper Threating where rendering benefits the most from ??
