Another new integrated renderer
-
Hi Nicola,
Thanks for the answers...
Have to say that I find your material editor extremely difficult to use...
There's so many terms used - not to mention steps you need to go through - just to create a simple glass material...I.e. How do I create a glass material, which allows the sun-light to pass through the window...??
@fluid said:
For example, you can create a small sphere an make it emit all over its surface, and you'll have a point light.
Now... I know this is doable, but I also know that even with an unbiased render it will increase the render time tremendously...
@fluid said:
Support for ideal lights like spot lights and point lights is planned, but since it can produce results that are not physically correct
Please don't explain to me about physically correct render applications...
If you take a look at my signature, I'm sure you'll find out what I refer to...In all other unbiased render applications I know, you have point- and spot-light as well as IES and projector light options and they're physically correct, so I really don't understand exactly what you're referring to...
@fluid said:
Can you please point out the which terms are you referring to? The material parameters?
In particular a lot of the terms used in the Material editor makes my head spin...
Is it possible to create layered materials...??

Hi Frederik,

Creating a glass material is actually quite simple, just select "transparent" in the scattering tab and "dielectric" in the medium tab. Or you can import it directly from the material library. Then set the medium precedence for your glass object to a value greater than 1.
Please refer to the "glass" tutorial for a step by step guide.
The medium precedence is necessary because it allows you to create transparent objects in complex configurations, for example a glass ball inside a water glass.@unknownuser said:

I don't necessarily agree with this, again, it really depends on the scene and lighting configuration. Please also note that there are other well established physically based renderers that don't have point or spot lights.

I'd like to distinguish between IES lighting profiles and point - spot lights. A IES profile (among other things) specifies the distribution of emission directions, which in FluidRay is called "directional emission" in the material editor. IES profiles will be just another type of directional emission, and will be already available in the next demo version. Point and spot lights, on the other hand, produce images that don't really exist in reality. That is really what I mean for "physically correct". Nevertheless, point and spot lights will be added to FluidRay pretty soon.

I'd like to take this chance to mention the design philosophy behind the material editor, which might look intimidating at first, but gives actually a huge flexibility once you grasp it. There are five tabs in the material editor:
-scattering - how light is scattered once it hits the surface, here you can distinguish between metal, plastic, matte, etc.
-displacement - how the surface is locally perturbed, for example with bump mapping
-area emission - how light is emitted over a surface, for example you could have that certain points on the surface emit more light than others.
-directional emission - once a point on the surface has been chosen for emission, here you decide how the direction is chosen, could be a cone of directions, or an IES profile, etc.
-medium - the type of medium that is inside the surface, it could be air, glass, skin, etc. This will turn out extremely important when we'll add subsurface scattering.
Having these five material characteristics vary one independently from the others really allows you to create a huge selection of materials.Nicola

It's true that some engines cannot do that... perhaps it does tell more about the used (or developed) algorithms than anything else. Nevertheless it can be done, even if some "established" renderers cannot offer point/spot lights. Besides of that, there are really few renders that can produce unbiased "Sun pool caustics" - caustics that are seen trough a dielectric material, when it's illuminated by a small and distant light source. That also is missing from "established" unbiased renderers

Yep, I totally agree.

Interesting language being used in your GUI. I always wonder why people are trying to reinvent wheel all the time.
Anyway .... I have tried file which perfectly renders unbiased in Thea, Twilight and also in biased like Vray etc. With Fluid , after 20min of (non responsive) mat export, had run out of memory message. I did not change anything ...really only clicked render button. So there were no reflection at all ...just matt materials, exterior render with sun and sky. I wonder if this is beta limitation or known problem with medium sized files. The file size is around 30MB.
And yes, before you ask me to send you the file... sorry, but can't do that. The renderer looks interesting although I am not convinced that some elements could not be automated and/or simplified.

Yes, FluidRay is still in beta. May I ask how many polygons does your scene have?

Nicola, welcome and good luck with your product. It is a big task I'm sure and takes a lot of time and effort to write such a program. I admire you for your resolve and determination. It's also tough being the new kid on the playground with the other kids being bigger and very territorial. Keep at it though and include the users in your layout decisions and I'm sure it will yield a great piece of software. Best Wishes!

Hi EarthMover,
Thanks for the kind words!

4.3 million faces. The file size 31.8 mb.

We just released a new demo version, featuring:
-Improved UI readability
-IES light profiles
-Layered materialsYou can grab it here: http://www.fluidray.com/downloads/

It looks like you have to go through hoops before you can render; I find Thea far simpler.

I downloaded and installed the FluidRay demo. The first thing I noticed was my Irender Nxt toolbar was missing. I reopened my Irender toolbar and placed it back on the sidebar, then set it to open automatically when SK starts. When I restart SK, it crashes once. When I restart SK again, FluidRays toolbar is in place of my Irender toolbar, even though I set it to start when SK starts up. Needless to say, I uninstalled Fluidray demo. I can understand one application not working if another one is installed, but isn't booting off another apps toolbar an act of war or something.

Hi Radeon56k,
We are investigating the issue. We hope you'll reconsider evaluating FluidRay.
