[Max] General Discussion / Re: Object ID pass

« on: 2014-09-03, 08:38:02 »

thanks , but bad idea for rendering sequence animation , i have 3000 frame "full HD EXR" to render , it will explode my hard drive .

No it won't. Corona can save compressed OpenEXR files, and big blocks of single colours like ID passes tend to compress really well. Having ten ID passes instead of just one is not going to increase the size of the frames by very much. No matter how much stuff you cram in there it's unlikely that your images will be more than about 50 megabytes each. 50 MB/frame * 3000 frames ~= 146 gigabytes.

Just buy another hard drive. *shrug*

1. Don't know.
2. Yes, works fine.
3. If they're normal VRayMaterials with standard maps then yeah it should work fine.
4. Yes of course. The Slate editor is really just a different display mode for the internal graphs. It doesn't mean you're setting up the data connections differently.

can you elaborate in brief please ............Thanks

I believe he was being sarcastic :) ...meaning it has unrealistic/surreal lightning

Which is silly, because you can use any render engine to produce unrealistic results. Redshift doesn't produce quite as realistic images as Corona, but on the other hand it is WAY faster, deals with large scenes much better, and has a bunch of other "production features" like volumes and whatnot. If you need really really good interior renders and don't mind the render time, Corona is a great choice. If you need features Corona lacks, or you need really fast render times, and you can live with the slight reduction in realism, Redshift is a great choice. It's basically V-Ray on the GPU.

Is that Red shift 3d  really worth buying ???? {a layman Q}

If you're a Maya or Softimage user, then yes. It's not as accurate or as easy to use as Corona, but it's really really fast.

I need 3.5K less than 20 minutes. 1 Hour or 2 per picture is not usable for the production. Corona has really nice renders but speed is key for me.

As long as a print-resolution image finishes over night, I'm not too bothered about render speed. But if you really need high-res in 20 minutes or less, your only really good option is to wait until Redshift is ported to Max in a month or two. A machine with dual Titans will render a normal interior at 3.5k in less than 10 minutes, I'd wager.

Edit: though keep in mind that Corona is the sort of engine where you need to spend next to no time at all worrying about render settings, and the progressive nature means that you KNOW you will have an image finished after a certain amount of time. Redshift is really fast, much faster than Corona, but you're right back in the V-Ray swamp of managing irradiance cache settings, light samples, anti-aliasing, etc etc etc.

Buy another machine or two and use distributed rendering. Or use Rebus; I think they support Max+Corona.


Corona is extremely fast for what it does, but since what it does is a very accurate simulation of light it's going to be pretty slow. Something like irradiance caching would speed things up but it would also remove some of the appeal of Corona.

In Photoshop it's going to be pretty difficult. Most of the filters don't work in 32-bit mode and you need 32-bit mode for the compositing to work. The only one that works is the bilateral filter ("Surface Blur"), so what you can do this this:

Combine the raw lighting outputs in add mode ("linear dodge") and then put the raw colours on top in multiply mode, and then put reflections and such on top also in add mode. Then you can run a surface blur on the lighting passes or the reflection passes or whatever to filter stuff.

Looks really lame.  The medieval thing took 37 minutes, which is not impressive in the least, and it's missing a lot of important GI.

-you have max bounces set to 128 and min to 3. In Corona you don't have such adaptive settings. If you were using defaults, it would be 25 bounces.

I'm pretty sure Corona has Russian roulette termination of bounces as well, actually.

Recursion is pretty standard in rendering. But with Fermi and beyond, CUDA supports recursion just fine (supposedly). OpenCL doesn't, however. Apparently you can do it manually by creating a stack, but it seems pretty roundabout.

Hardware / Re: Corona - Titan black SLI or Titan Z?

« on: 2014-07-01, 15:30:05 »

The Xeon and i7 are the exact same CPUs for the most part, the only difference is that you need a Xeon for a multi-CPU setup (which also requires a special motherboard with two (or more CPU sockets) and the Xeons are available with more cores. If you have a high budget, a dual Xeon system is pretty awesome. But it's also super-expensive. For the most part it's not worth the money.

Might I make a recommendation though? If you only have basic knowledge of computers, just buy one!

Corona doesn't use the GPU at all, for anything. Buy whatever you need for viewports.

Edit: Also, go for a six-core. The extra cores will help when rendering in Corona.

Is it render in Corona?

It's clearly been done in an engine that doesn't have a white balance setting.

If you don't have vray you can use the "skew" modifier... Not as nice as the vray cam... But works fine!

Just beware that the "skew" modifier will, just like V-Ray's "guess from vertical/horizontal" shift actually zoom out the more of a 2D offset you're using. The only way to get correct lens shifting inside Max is to use V-Ray's shift, and leave the "correction" alone.

Is that material setup object wrapped in cloth available anywhere? I'd like a copy of it, if possible.
