I'm suffering this too, overbright material editor slots.

looks like they need highlight compression ..?
.. Exactly.

Thanks a lot, that was informative :)

My current rig is..
Intel core i7-4770K
16 GB RAM
GTX 650

So if I need to get faster performance, should I upgrade my Processor, or the RAM or both? and how much is the contribution of the RAM in the rendering process with Corona?

it may sound obvious but, did you check ".../My Documents/3dsmax/renderoutput" ??

Transparency always comes with a cost. Look how drastically rays/s gets reduced in second render - from 4,5M to 2,8
If you're using bitmap in opacity slot, you should take special care in what format you choosing, as there might be a huge difference in performance: https://forum.corona-renderer.com/index.php/topic,4249.0.html
No, I don't use any bitmaps in opacity, only a procedural Falloff, from white to very light grey.. but thanks for this piece of  info :)

No no no, yes :D i could be more explanatory here is the link https://forum.corona-renderer.com/index.php/topic,1012.0.html
What i want to say to you, by looking your material, your white is too white...
Basically nothing is white 255.255.255 so if you make bunch of materials in your scene too white it will make your render times higher. So instead using 255 for white you should use 170.170.170 or use 255.255.255 and set level for diffuse to 0.7.
What are you referring is albedo element it is used just so it make it easier for you observing what has high albedo by showing it in red(you can switch to it in corona VFB)
Please read about it as it is well explained in forums.
Also this is just as starting point and one possible reason of your high render times and it is reasonable to expect render times going up when you use translucency, caustics or scene with more complex GI or materials.

Thank you a lot Coronaut, I usually do not use 255,255,255 in my scenes, nor 0,0,0 as black, but sometimes I use 220,220,220 or 200,200,200 but that seems too high for Corona too, so i'll stick with 180,180,180 for a maximum white value, that's one thing I learned.
Actually using Albedo element is so useful, I discovered that the cushions on the bed are too white, and I reduced there value and the "Red" in Albedo has gone and the render time was reduced by 1% (fom 8:23 to 8:19 ), so there IS a change in render time.
Next thing is, as I'm writing this, I brought the curtains back and they are SUPER RED in the Albedo element, so I'll reduce their white value and try again and see what I can get.
Thanks a MILLION Coronaut for directing me towards that Albedo thing :D

Yo mate, please search "AlBEDO" on forum, things will be much clearer after.
Wow.. I'm more confused now :D .. can you give me a little bit more direct information.
But what I understood from all of what I read.. that if something appears "red" in the Albedo element, then it has too high diffuse/reflective white value. is that true?

Hi guys,
I'm having an issue with the curtain material, that is slowing rendering and making it more noisy, here are the renders with and without curtains, and the curtain materials settings. render settings are default, lighting is only Peter Guthrie's HDRI.
Please tell me if that is normal, and if it's not what am I doing wrong?! and what is the best way to achieve a good looking+fast rendering curtain, and how if I want to exclude the curtain from HDRI?!
Thanks

I don't like this licensing model at all. Yes, it's new and innovative, and supposedly the super-duper-Saas model is very fair to the final users. But in my humble opinion it's not. The first licensing proposal had to be completely redone, because it was so completely unfair for the box model and heavily biased towards the Saas model. And even now, after the changes (thanks guys for at least including payed updates in the box model...) still is.

I look at the Box model and think about Corona as a render engine in it's baby stage, a very promising baby by the way. But let's not forget that there are a ton of features that haven't been implemented yet. I'm very sure the development team is going to do a great job, and give us a full fledged render engine, no doubt about it. But come on... the baby 1.0 version, is the same price as the competition (Octane v2.x is 459€ and Maxwell v3 is 446€), and if you're not lucky enough to get the promo discount you're either left with no updates, or paying 100€ more. Those are way more developed versions, tried and true... those are grown ups compared to Corona. Doesn't seem so fair right?

So then I look at the Saas model, supposedly the fair option. But to me it's just a neat way to get you hooked into the system. Very easy to step in, affordable at the beggining and "you are always free to take the door and leave". Of course you are.... and then in 2 years time, when all your libraries are converted to Corona, all your workflow is optimized for Corona, all your work has been done in Corona, and all the time you have spent in mastering Corona ... are you gonna leave? After two years, when the licensing costs are starting to get equal and you see your mighty Saas slowly overtaking the box model costs, will you want to leave and be left with nothing? I guess not... You're going to be hooked with no way to step out, cause once you stop paying for the Saas you're left with just a crippled demo version. And nobody wants that. That's when the money leak starts, and you wish you had bought the Box version.

If only the Saas model would give us the chance of owning the software once the box model price was met, meaning you could really step out of the game and at least keep a usable piece of software you have paid for... I would see it fair. But right now it just doesn't add up. We're either blind-buying the baby-box model at a higher cost than the competition, or stepping into the leaky Saas model.

Now I see things differently.. You are absolutely right!!

sorry, I did not supouse that you don't have photographic exposure checked on!
NVM, I really appreciate your help :)

11
If you want to use "photographic" exposure controls, then you definitely need to have use photographic exposure checked. OTOH, why do you want "photographic" controls if you don't have a clue what it does? Use arbitrary exposure control (EV) - it's much easier to understand.
 
p.s. you really don't need to touch film width control, unless you know what you're doing.

I think you got me wrong, I know what I'm doing (as I've been working in arch-viz for nearly 12 years, I suppose that I know what I'm doing :D), the CamMod just is not responding, that's what I'm saying.
a straight question, Should "film width" in CoronaCamMod  affect the "view" in the viewport? or it just appears in renders?

The lighting is great, but the scene feels empty, you need to add some details and to work on more detailed textures.

13
But I am wondering, Do I have to check "use photographic exposure" option or not?!
and if Yes, what does that have to do with the Film Width?!!!

14
Do you mind that f-stop for example does no changes in Relation to the Film-width or f-stop does No changes at all?
No, it doesn't change at all, I may send you 2 renders with different F-stop values, OR ISO values with everything else is constant, but sending them won't make any difference as they are EXACTLY the same.

I watched this on Behance, but WOW was that in Corona, that's AWESOME :)
