whoa, this thread exploded ..



will have to try this when i have time ..

where can i pay ? if this works decently enough for me, i'll stick to my word !

Or can i pay in chocolate ?
-->

about 8 or 9 years ago when i started my architectural studies, i wanted to use RealFlow for one project. So i wrote to NL to ask how mach the educational version was. The answer was 800$. So i wrote that this was too much and i could not afford it. An answer came from NL support that they wanted me to use RealFlow and that i can pay what i could afford to get my educational version. So i payed what i could afford, which was about 300$ if i remember correctly and indeed i did get the edu version of the latest RealFlow available. I guess 1.x.
This is why i was then and still am a proud NL user.

What i did then was asking the NL support if they liked swiss chocolate - of course the answer was yes - and i sent a package worth of 40$ swiss premium quality chocolate to spain. And everybody was happy !

Is there a way to create a render without shadows? To use this AO-type pass to it's fullest, it seems like you'd need a base without the effect. Otherwise, it's sort of like having a reflection pass and a regular pass (rather than a totally diffuse pass).

Hello Brodie,

Getting a render without shadows is not possible today in Maxwell (nor recommendable).

Keep in mind that the exported shadows are meant to add new shadows from 3D object to a live footage, for compositing purposes, but not for adding-removing shadows over the pure 3D objects (which they already have the shadows from the rendering).

At least not in an accurate render engine. The best way to control the intensity of certain shadows is changing the illumination setup, like a director of photography does in an studio.

But the independent shadow buffers are meant for compositing purposes, for adding shadows over a shot footage, not altering the shading of the 3D objects.

Dario,

Fair enough, I don't know that I'd really want to get into determining my own shadows anyway so I'm sort of playing devil's advocate a bit. That said, do you see a difference, then, in applying shadows to a nonshadowed 3d rendered object vs. having the ability to apply reflections to diffuse 3d rendered objects (rather than adjusting lighting setups like a photographer might)?

-Brodie

Hello Brodie,

The separation between Reflections and Diffuse was developed for compositing purposes as well: Add reflections of a rendered 3D object into a life footage.

Imagine you have a footage with a lake, and you want to include a ship on the lake. You render the ship, and use a dummy reflective object mimicking the lake, just to catch the reflections of the sailing ship.

The reflection can be added to the footage to mimic the reflection of the water of the 3D object
(anyway it is a compositing trick).

Keep in mind Tom's words: one thing is to be physically correct, and other thing is to be available in real life.

Is there a way to create a render without shadows?

Here You are

... Getting a render without shadows is not possible today in Maxwell ...

I would leave some comment but It could be insulting again. It was possible even in 1.7.1 version.

[tom]

Could you demonstrate the same workaround with glossies and dielectrics?

[zdeno]

What more can I do for You my Master?

[tom]

Are you placing a metal ball and a glass sphere in front of MXI lit stuff?

[zdeno]

I don't understand what You wrote (my english is not so good as I said)

it looks like this in studio




but yes there is metal and glass ball . It is glossy and dielectric as You mentioned.
Is there something wrong?

There are still no shadows . only fresnel ramp appears.

[tom]

I mean the Simball is an MXI emitter, no?

What happened to the specular reflections in your workaround?

[zdeno]

Yes of course. everything is ONLY emitter in first picture. there is no single BSDF to "catch" shadow. only direct light. loud and clear at 6 SL maxwell fast as hell.

In second example balls are hidden from GI to not disturb free light flow. Just plain refraction and reflection.

edit:

What happened to the specular reflections in your workaround?

it is gone. can't You see?

It was not a subject to have specular reflection NO SHADOWS that was a goal. Or I misunderstood english words once again.

[tom]

NO SHADOWS that was a goal. Or I misunderstood english words once again.

Is there a way to create a render without shadows?

Maybe Brodie can approve your method, padawan zdeno.

Official answer is: "No"

[zdeno]

What is Official answer of Council now, Master?

[tom]

Here's how a render would look without shadows...



Multiplying the shadow should produce the final image.

What is Official answer of Council now, Master?

I admire your efforts in making night lights.

[zdeno]

I admire your efforts in making night lights.

I am flattered

So it is suddenly possible to render some pictures without shadows (with a little postpro) ?

it is great way to get fast and professional answer. just step on Master's toes

I thought to use shadow layer to get shadowless picture, but we all know, "shadow pass" have a ..... small flaws in 1.7.1 ( not to be insulting anymore)
I am now waiting for service pack for 1.7.1 version. but I am affraid it would be "unbiased waiting"
