General Discussion / Corona Mirrored HDRI Correct or Wrong?
« on: 2019-08-16, 16:01:39 »
Does anyone know what is the deal with flipped hdri reflection? Same hdri same scene same glass mtl same camera settings. Left is corona right is fstorm.

So I did put my name in red on hdri. Loaded in corona and fstrom. When I was looking directly into hdri with camera, with corona my name was written backwards. But in a mirror it was written correctly.(Which I assume is the correct way)...


With fstorm did not matter if I look at the hdri directly or in a mirror my name was in a correct orientation. ROMAS and not spelled backwards.

So in this example(attached) you can see that reflections are different but it has the same scene setup. Even the shadows are flipped.

Does anyone know anything in regards to this situation? So which way is the correct way? Is Fstorm is doing this right or corona. I assume corona is doing it right ;/

BOTH SCENES ARE IDENTICAL

What do you think?

Hello everyone,

I have one problem with corona and forest pro Object ID.

So I created a lawn/grass with Itoo Forest Pro. The grass geometry is custom made, but this is not a problem.

The problem is - when I pick Corona MASK element in the elements tab. I sed it to RGB and a checkbox on OBJ ID - which is 1-2-3. So in my case I right click on the forest pro object go to properties and put object ID as 1.

So my MASK element RED channel 1 should show the grass mask. But its rendering it in BLACK. Basically corona obj ID buffer does not see that I set 1 obj ID on the grass/forest object.

Is it that forest pro is not suported in corona elements or how does it work? Or should I just go on the object that I am scattering it and select the ID there first.

I am a bit lost. Please help :)

I need help / Corona Glare
« on: 2018-10-01, 13:15:11 »
Hello guys,

I have small questions here regarding corona GLARE.

Is there a way to give some kind of dispersion in corona glare? Something like in my example attached. This glare can be achieved in FStorm. I am not proposing FStorm. I am a full user of Vray and Corona.

I am just asking is it possible to do something similar?

I need help / Layered Material - Problem
« on: 2018-02-09, 10:55:34 »
Hello there everyone,

I have this issue with corona layered material.

Really simple - I am creating a beach scene.

So material setup really simple: Corona LayeredMtl. The base mtl has a DRY sand with displacement and the second material below has a WET sand (no displacement)

And I am masking these to with a map channel 2. Black and WHITE MASK.

When I press render I can see the dry and wet sand blending fine. But the whole plane(beach) is using displacement from the base material. Even the wet sand area has displacement. (AND IT DOES NOT)

Its like its working with the duffuse and such but displacement is only working on the base material. ;/

Can anyone help how to solve my problem.

How should I approach this situation.

I want the dry sand displaced and the wet sand becoming FLAT. (no dispalcement)

Thank you.

I need help / CORONA SUN+ SKY VS HIGH QUALITY HDRI
« on: 2017-09-15, 12:01:34 »
Hello there,

this thing that I have to get off my chest.

The purpose of using a HQ HDRI versus just corona sun+SKY.

WHY?

I did some tests simple scene nothing special just to see how the lighting works and the shadows are behaving.

I did put a high quality HDRI from www.hdri-skies.com and mediterraneanlight.

the thing is I was able re-create that effect and that lighting of a specific HDRi with just corona sky and sun controlling them together almost 95% accurate.

Which I have never was capable to do with VRAY sun and sky. Vray sun and sky works a lot different than corona sun and sky. Its just not the same thing.

So I am in a cross road now. I can use Corona sun +sky for the lighting and I can put whatever HDRi map in the reflection, refraction, direct visible slot. For nice reflections.

+with sun+sky you have a lot more control regarding animations sunrise - sunset and so on.

Anyways - I would like to know what is your opinion on this one regarding ONLY CORONA sun+SKY VS HDRI.

Because corona sun+SKY is a very good quality HDRI alike replica. With very nice easy controls.

I am just curious what other people think or have to say from their own experience.

Hello there,

Just wanted to ask for rendering images from 10 000 to 25 000px with corona.

What Render settings should I tweak? Because in a 15k image you can introduce noise, that will not be seen that much. Because its a massive image and it will be printed o a massive wall or fence. With for example 72dpi.

For example to do it with vray is very easy. Just lower the MIN MAX in iraddiance map for example -8-4 or even higher and lower down the color threshold to 0.03 or 0.04 ant it will render it blazing fast.

What about corona. I am on corona 1.5.2

I have 128GB of ram DDR4 2400. MEMORY is not a big problem for me.

Let me know guys, thank you very much.

I need help / CORONA LIGHT PROBLEM
« on: 2017-01-04, 17:32:17 »
Hello everyone,

I started using corona after 9 years of Vray.

And I noticed one big issue with corona light plane,disc,sphere does not matter which shape it is.

So it has:

Visible Directly
Effect Reflections
Effect Refractions
Oclude other lights

So for example. Lets just say I have a quite big room and only one pendant light in the middle of the room. A put extra 2 corona planes just to push some more light in.
So I remove visible directly and oclude other lights check box. So what do I get? I get a nicely light scene, with speculars on my materials from those lights and everyhing.

But what I also get an ugly reflection in the mirror of those two corona light planes. So thats fair enough - I go to those corona lights and turn Effect reflection OFF. And there I get no ugly reflectionin the mirror of them.

But I did notice another thing that I am not getting those speculars from those two planes anymore. The materials became flat and dead. And corona light does not have a checkbox called effect speculars.

Basically if you turn OFF effect reflections you are loosing all the speculars at the same time. Which to me sounds weird. Is there a way to seperate reflections from speculars with corona light?

Thank you very much.
