A little bump about memory choices.

I have a Crosshair VI hero with Ryzen 7 1700, which memory can I buy ?  (4x16gb)
G.Skill Flare X 2900Mhz C14 (expensive)
G.Skill Trident 3000Mhz C14
Corsair LPX 3200Mhz C16

Hardware / Re: Low memory issue - Config

« on: 2018-11-13, 17:04:15 »

I already try to check my assets, nothing crazy.
But I have a volume fog and few render elements with denoiser on (8-9 lightselect elements, etc..).
Right now I can do the render with enough resolution I need but making the upgrade to 64gb will be still usefull.

About that, in my computer I have 4x8gb G.Skill Flare X 3200Mhz on my Asus Crosshaire Hero VI motherboard and I have to buy 4x16gb.
Which RAM can I buy ?
G.Skill Trident ? Corsair ?

Any advices ?

Hardware / Low memory issue - Config

« on: 2018-11-09, 09:22:25 »

Hi guys,

So, as the title say it, I have some low memory issues for the first time with corona.
I have a Ryzen 7 1700 with 32gb (4x8) and looks like I need 64gb.

Here is my question;
I'm gonna buy 64gb (4x16) but what can I do with my old 32gb (I can't keep them in my computer, the motherboard have only 4 memory slots) ?
I'm also interested to make a render node and use my old memory for it but 32gb is enough for a node or I'll have the same memory issues ?

Any advices ?

[Max] I need help! / Hdri question

« on: 2018-09-28, 11:36:56 »

Hi guys,

So, I have some questions about hdri usage in corona. Sorry if that's already explained in another post but I didn't find the good answer.

I was using Corona 2 yeas ago and I have to go back to Vray till today. At the time I think I (we?) was using HDRI with VrayHdrimtl. I mainly used coronasky ('cause it's awesome) so I don't remember if there is another way to use correctly an HDRI.

Today I'm come back to Corona and I wanted to use an HDRI, should I use Bitmap mtl or CoronaBitmap or something else ?

In VrayHdrimtl we have Overall multiplier, Render multiplier, .. do we have (need?) something like that somewhere ?

Hardware / Question - Storage

« on: 2017-06-16, 21:21:45 »

Hi guys,

I'm looking to make a little upgrade on my computer (it's an old station) and I wondering what's the most usefull solution about the storage.
It's a station without ssd (yes, it's an old station :)) so I'm looking for 1 or 2 ssd but how are using your drives ?
1 ssd for system only and another one for software and main projects or first one for system and software  and another one for your main projects ?

FYI, I will make a major upgrade (cpu, mb, graphics) in few months but right now I really to get a ssd drive. :)


thks !

Ok,

I can say it's change but not perfect. :)
I didn't saw the displacement parameters in the material. ^^

Thanks !

I can work on it !

Hello guys,

I'm already working on a new scene with this lovely alpha v6 :) and for this scene I need to use the displace (first time with corona).
And ... well
I have saw that it's better to use the " Screen size " instead of " World size " and the material is on a plane.
The tiling of my diffuse and displace map are the same but I don't understand why I have this result. Did I miss something ? :s

It's pretty nice !

But for me, there is two things a little bit disturbing.

- The table, or more precisely, the feet. It's look like some kind of plastic or something else and I think with a metal like chrome or aluminium it'll be better.

- Your pillows ; It's hard to explain but there have a lot of folds but they don't look soft. The surface looks hard, like plaster. :s
Maybe it's your fabric's choice in Marvelous Design. Try something more thin, coton works fine.

Thanks for this explanation, do you by any chance have links to those sites with list of IOR numbers?

It's not a real complete list, just few words but here is the link
http://viscorbel.com/vray-materials-theory/

For the lazy
"
water 1.33
plastic 1.45
glass 1.5-1.8
diamond 2.4
compound materials like wood, stone, concrete etc 3-6
metals 20-100

Exact values need to be fine tuned for each material to achieve the right look.

Yes, I have a high IOR for that material. I'll try too explain that.

First, I've found on some sites (viscorbel and others) a small list of IOR (reflection) for some materials and all compound materials (wood, stone, concrete,...) are between 3 and 6 IOR. (water 1.33, glass 1.5 to 1.8, metal 20 to 100).
So, I have some numbers now.

Next, it's understand how the IOR (reflection) is working. For that, I've found on another site (Neil Bevlins) a lot of explainations about that.
And, the lower your IOR (reflection) value is, the less you will have reflection in front of the object (but you will have reflection on the side). And with a higher IOR value, the more the reflection will be uniform.

Best example is the glass.
When you're front of  a glass, the reflection is very low but if you look the same glass on the side you will see more and more reflection (depending of the angle).
For woods and others compound materials the reflection is less influenced by the angle.

So that's why I use higher value than usual pour my wood material.


p.s.: English isn't my mother language, so I hope I'm understandable and I hope too these explanations will be useful for others.

My first "first" render was with PT+ HD and all default settings (pt 16 - msi 20) it was not so bad but a lot of noise (in the reflections especially).
I tried different settings and the best result comes with a higher msi value (and maybe with max records too).

I think I have read somewhere that for interior pictures it's better to use a high msi (200 ?) and for an exterior, a lower value is enough (40).

But I'm still at the beginning of my Corona's Adventure, so we'll see ! :)
