Do you know what sort of limits have been placed on the demo?

Great glass material. Is the glass geometry intersecting, flush or is there a gap between it and the floor / ceiling? Also is it chamfered or just a box?

« on: 2014-02-01, 00:52:52 »
Not necessarily, the only settings I would change in your situation would be the light samples multiplier (I haven't needed to ever raise this above 32, most times to 6). I would strip your scene down first as described before you start messing with the settings.

Usually when I experience problems like this I'll break my scene down bit by bit and try to figure out what's going on. Seeing as you've got a lot of stuff happening it might be worth while hiding all complex geometry and applying a white material override and see how the noise looks then.
If it's still noisy, hide lights individually. For example, I'd do a test render with just the main geometry with the override material applied with a completely black environment, with only the exterior lights enabled. Then unhide the interior lights / hide the glass window opening geometry so light can come through. Then add back the skylight.
One other problem that I've faced similar to yours is using a combination of max lighting + Corona, it just doesn't work smoothly at the moment. Make sure every light in your scene is a corona light.

I agree, that scene seems to cover all the bases for properly evaluating a material.

[Max] Corona Goodies - User Contributions / Re: Highlight Compression Macros for Eyeon Fusion + Foundry Nuke
« on: 2014-01-29, 02:46:58 »Damn that example image really highlights why filmic mapping is superior.
I know the dev team hate unnecessary requests but would it be possible to have the option to utilise filmic compression mapping from within Corona (as an option to the standard mapping)? Shouldn't be too arduous to implement as the code / algorithms are already available here.
This could be something that really sets Corona apart from other renderers, so I don't think its a totally frivolous request. Arch viz shots with good contrast and saturation without burnouts straight out of the box = hnnnnnnnnng!
Yes I've asked for this since day one :)
I've asked for something similar to 19lights version.

Great application of HDR tone mapping! Might be cool to do some sort of hybrid HDR / filmic mapping?

Thanks, much appreciated!
I just got it working, so far so good! Although I am a little puzzled at some of the names of the sliders...would you mind giving a quick run-down of what the sliders do? I guess the "holy grail" would be to find some settings that could town down burnouts whilst retaining contrast and saturation is the rest of the image (kind of like the comparison image posted earlier).
Also, when working this way would it be advisable to render a scene with good overall illumination with visible burnouts, and post process the burnouts out after. Or underexpose the scene / use reduced lighting levels to avoid burnouts and bring the levels up after in post?

Opened up the eval version of Fusion, this is how I felt:
Can anyone point me in the right direction on how to get this going to a complete fusion noob? Or would Nuke be better for a compositing beginner?

[Max] Resolved Feature Requests / Re: Scattering by mask
« on: 2014-01-28, 18:20:06 »
+1 to this.
Would love to see some love for collisions too. I can't seem to get multi-scatter collisions working with Corona Proxy objects. What would also be cool is some complex collision solvers whereby we could use low poly meshes to calculate the collisions, as opposed to simple bounding boxes.
Would be great to have everything in one place.

« on: 2014-01-22, 14:26:01 »
No worries, I'm no expert and my mat isn't finalised either :) I guess it depends what you're going for, I was trying to get a darker more industrial galvanised look, where the reflections aren't quite so prominent:

Ok so I've imported your material into one of my WIP scenes, you can check it out against my current galvanized mat. Let me know if you want my settings?

I'd say you're pretty much on the right track with that test. You might just want to tweak the maps in the reflection and glossiness slots to produce stronger reflective and glossy changes (slap a colour correction modifier on the same map and play with contrast / output e.t.c).
Post up your current mat settings so we can see what's going on. Perhaps you could try putting some maps into the anisotropy / rotation slot and see if that produces the desired effect?
It might also be worth putting the mat on an different objects in a scene with real geometry around it as the environment is so crucial to the look of the reflective material.

Looking good! One critique would be to lower the exposure in a few of the shots to get things looking a bit more dynamic.
May I enquire how you did the grass? It looks really good. Are you simply using a "mud" texture for the geometry underneath the grass?

Work in Progress/Tests / Re: Trying to convert
« on: 2014-01-18, 16:13:17 »
The problem is that you have tried to convert a Vray scene without knowing much about how Corona works. Conversion is never a 1-click process. You will get errors and slow downs. The scene you have posted should not take anywhere near that amount of time to render. Other users on here are putting out amazingly photo-real 4k renders with zero noise in about 4-8 hours.
I suggest you read Rawalanche's post on how to use Corona properly in this thread http://forum.corona-renderer.com/index.php/topic,2518.0.html

Off-Topic / Re: Your OTHER renderer?
« on: 2014-01-18, 16:04:40 »
Ex Vray user checking in!
From the moment I started a render with Corona I knew there was no going back. It is SO nice to not have to worry about GI splotches, blurry lighting solutions / random HDRI dots e.t.c - problems that I faced with Vray on a daily basis (unless I brute forced everything = slow as hell).
One other absolutely amazing benefit of Corona is not worrying about glass. I do a lot of arch viz stuff where my clients want glass everywhere with complex lighting. Unless I did some serious fakery in Vray this was a real pain.
Kudos to the Corona team! Can't praise this renderer enough.
