Feature requests / V-Ray IPR and Corona IR
« on: 2019-06-15, 13:19:08 »
Hey guys,

Recently tried v-ray 4.20 and although it still isn't any faster on production rendering than Corona (I'm getting Corona being around 70-100% faster), their approach to IPR/IR seems to be more "fluid" than Corona. Can't quite put my finger on it but I suspect the following:

1) Initial image feedback seems faster, even if it is more "degrading" initially. I quite like that approach. Is it possible to replicate it for Corona?
2) Window resolution is much more flexible, allowing us to set any window size we like. I'm aware this has been an onward discussion for a long time but this combined with a faster visual response would GREATLY improve usability IMHO.
3) Being able to make several render regions without having to press SHIFT also seems to be more user-friendly in giving that impression of a fast response.

Don't get me wrong, Corona IR is very fast once everything is computed. It's just that initial response when V-Ray IPR gives you a degraded image almost instantly when Corona IR stays black initially for a couple of seconds.

Also, apart from all the IR suggestions, when making a render region in production is "Computing GI" necessary to be processed for the whole image? I remember a Corona team member responding about this issue and saying there was no way around this. I think V-Ray works without having to process all image data when region rendering although I'm not quite sure about that.

I need help / Custom aperture maps
« on: 2019-06-07, 00:07:32 »
Saw this image the other day on a facebook group and I was wondering if someone knows where can I find such custom aperture maps? Paid or non-paid.

I remember that the highlighted obstacle map was included in the old Maxwell Render installation but that's about it.

As per the new v-ray release :)

General CG discussion / Working remotely (reduce lag)
« on: 2019-05-31, 15:49:06 »
I'm curious to know how do you guys work remotely.

Currently, I have the simplest method by using Teamviewer on my home computer and office computer, but, as you may know, lag is an issue especially when modeling. Not to mention the fact that sometimes shortcuts stop working randomly (W move tool is a prime example).

Would seriously like to know how can one reduce lag as much as possible when working remotely. Been hearing about VPN but I have no idea how to set it up.

General Discussion / Corona Denoiser vs Nvidia Denoiser
« on: 2019-02-15, 13:10:26 »
Hey guys, just wondering if this is normal behavior:

Since Nvidia Denoiser implementation in Corona, I hardly use it because to me Corona Denoiser is exactly the same speed on my dual Xeon 2696 v3 against my GTX 1070 Ti. My question is: is this expected? I seem to remember in V-ray the difference between Vray denoiser and Nvidia denoiser with the same GTX 1070Ti was more evident meaning Nvidia denoiser was faster than V-ray denoiser. Is Corona denoiser more fine-tuned speed-wise than Vray denoiser?

Feature requests / Clipping warning in VFB
« on: 2019-02-15, 13:00:26 »
Is there any clipping warning tool I'm not aware in Corona? Similar to highlight and shadow clipping warnings in Camera Raw or force color clamping in V-ray? Anything that enables clear clipping visualization inside VFB?

Feature requests / In-camera "copy to render settings"
« on: 2018-12-27, 00:32:35 »
Sorry if this has been already asked, but just like fstorm has, is it possible to have a button "copy to render settings". Useful when tone mapping is already fine-tuned in one camera and to avoid having to fiddle with exposure on render settings.

Hardware / 10 Gigabit Ethernet Performance
« on: 2018-07-29, 00:31:36 »
Hello guys,

So, I was thinking about buying another dual socket workstation and connect it directly to my other dual Xeon workstation via 10gbe PCI cards so I could further improve speed.

What performance should I expect from this sort of setup? Will the slave computer react swiftly (as in participating in the rendering) just like the main one when dealing with interactive rendering, for instance?

If so, what PCI cards would you recommend? ASUS XG-C100C maybe? Thanks!

Hardware / Quadro K1200 upgrade
« on: 2018-07-15, 21:45:54 »
I'm mostly interested in 3ds max smooth viewport/high FPS. What graphics card would you recommend? Should I stay in the Quadro line like M4000/P4000 or should I buy the GTX 1070/1080?

I'm pretty sure this has been asked before because I remember reading it a few months ago but I couldn't find it:

When doing render region on VFB the previous render should not be cleared.

I'm trying to get used to work with my Wacom intuos inside 3ds max. Switching between 3dsmax and ZBrush can be a frustrating experience when it comes to Viewport navigation. 3ds max does it one way, ZBrush does it completely differently.
ZBrush's viewport navigation is elegant and fast to use. Just press the LMB or pen press to rotate around. Press Alt+LMB to pan and release ALT while pressing LMB down and dragging the pen to enter zoom mode. I'd love to be able to do this in 3ds max without having to press any of the pen buttons. In Max i'm unable to assign just LMB to rotate let alone enter in zoom mode with the Zbrush finesse :) Any ideas?


I often use IR as an extended viewport and i was thinking if there's any way to bypass the "Click to start interactive session" message by for example assigning a macro to a script that starts IR and automatically ignores that message and starts right away. I know i can assign a keyboard shortcut to start IR window but is this possible for "activeshade mode"?


I need help / Noise flickering
« on: 2016-12-27, 16:18:36 »

I'm using PT+UHD in a few dollie animations but i'm getting noise flickering no matter if i save uhd cache in 30 frames interval and loading them from file.

In the example in attachment (90frames) i'm only using 40 passes (full denoise amount 0,6), maybe i should raise the passes so the noise isn't perceptible? It was done using "load from file". The .uhd file was saved using only the 1st frame of the animation. But if i use the middle frame the result is the same.

Thank you! :)

I don't know if this is the proper place to have an answer but here it goes: i just installed my second Xeon 2699 v3 on my Asus Z10PA-D8 and while Corona (and Cinebench) handle all cores (36) and threads (72) just fine while rendering, vray only uses ONE cpu. Setting affinity doesn't work as it reverts back to using one cpu even if i check the turned off cpu.

I'm using Windows 7 Ultimate x64. It scores 4376CB by the way :) Will i have to install Windows 8 or 10 to release all its potential? One more point in favour of Corona i guess...!

General Discussion / Corona Interactive vs Vray RT (CPU)
« on: 2016-06-07, 19:45:51 »
I'm testing my single (soon to be dual) Xeon 2696 v3 and i'm amazed at how fast Corona Interactive is comparing to Vray RT (cpu). Vray RT crashes at times and is not really usable in production to test the lighting assuming we keep materials and don't use material override. No crashes on Corona.

I'm curious as to why can't vray reach the level of speed of Corona Interactive? Production Render times are almost equal to me between the two since i still use IM+LC on vray. The differences of interactivity between them are really really noticeable though.
