sdds's simulation of vray (fakeosity)

[sdds]

Hey all, I am just experimenting with some more fakeosity techniques. What do you think? I am trying to simulate a vray image, vray is not available to me at the mo.

[sdds]

Well I use cinema 4d on a mac. Glad you like the image I am now trying it with c4d's gi engine.

[STRAT]

since Simulation ( multiple spherical lights ? ) is good but its not PRODUCTIVE and Practical .

 

talks a man who obviously isn't skilled/experienced with it

[sdds]

talking sense again strat, how you doing I am still playing with the GI controls in C4D m8. Finding it hard going I must admit.

[sdds]

Here is the gi render, without AA took 20mins.

 

I do agree with you to an extent cryptonx that vray for a still is efficient, but for tight deadline animation projects one maybe better off faking, more control.

[Frosty]

Its very good Simon. Tweak the levels/colour balance a little in PS and you're money.

[Frosty]

Anyways , yes I was just going to suggest finding a GI engine for C4D , since Simulation ( multiple spherical lights ? ) is good but its not PRODUCTIVE and Practical

 

Simon's Faked GI is better than your VRay GI - compare them for yourself. The tools are not as important as the user. Its been stated over and over.

[sdds]

Thanks for your kind words, really puts a spring in my step. I really need to improve my work to get a good job in viz. Am working on an optimized gi render using faking techniques to lower render times stay tuned.

[sdds]

Optimized GI, rendered well with only one bounce setting.

[sdds]

Ok this is my final render of the day, I hope you like it.

 

Completely faked a total of around 7 lights have been used, I am quite pleased but there is always room for improvement. Please criticize chaps, I plan to finish this tomorrow.

 

This is the company I am trying for, there quality of their work is good. http://www.archiform3d.com

[sdds]

Woops! here's the render

[Koper]

good stuff Simon

 

so you looking to go 'Down Under' I see

 

I think the process you just did is a very good techn. to study how light works. You'll go far with the knowladge

[sdds]

Oh damn, thought they had a office in London, good to aim for work wise though.

[Tommy L]

Your wall material on the right is a touch scrappy, is it supposed to be wall-paper? And the AA settings need boosting a bit.

All-in-all tho, a nice lighting study. I totally agree with the necessity for knowledge on faking for tight deadline animations. Also, a well rounded artist should know all of the tools in the box. In a studio, you sometimes take over other peoples projects or work in a team. You are right to study this lighting technique.

Not to take anything away from Simon, but I disagree. For a beginner, Karem's work is very good. And for fake GI in C4D, Simon's work is good too. I find the aliasing artifacts very distracting though, and the lighting to be a tiny bit dismal.

[sdds]

Thanks tommy, yea the wall material is crap I just threw it on quick, will amend later. Glad you like the image, it may not be worth the extra hassle for stills but I will use it for animation projects.

 

Possibly not enough realism for a still, you think?

[sdds]

Thanks Fran, will look into that lighting, thats the kind of feedback I need. Could this be adjusted in post like more saturation maybe?

[Fran]

Yes Simon, I would definately experiment with that. Also, if C4D renders out passes, you can do all kinds of interesting things in post.

[AJLynn]

Kareem's stuff is quite good for a beginner, but I must respectfully disagree on one point - trash talking like that requires more to back it up

 

But anyway - great work here, and I think you can start calling it "rendering" instead of "faking Vray" - because if your goal is to fake Vray, or if that is the name you're giving it, you're unfairly limiting yourself to being just like everybody else. If you set your own goals you can start doing much more interesting stuff.

[sdds]

Yea I am not trying to fake vray, just improving my understanding of lighting.

 

Fran this was done with passes, AO pass added.

[AJLynn]

I meant talking trash on Cinema and Mac. There will be none of that.

[edub]

HI,

 

just thought I'd jump in and try to figure out what's going on.

 

The first image is faked GI? but the second has GI? I didn't see the rendertimes for the first image, so I can't compare the two in that regards.

 

That said, I think they're both pretty good - but what are we trying to decide here?

 

Maybe an explanation of this faking technique would be a start? _i'm lost on that one.

[sdds]

Ok edub, first image was rendered in 20mins, second (gi diffuse 2) about 35mins. I am just improving my lighting skills, prob use gi for stills but better knowledge will give me better results at faster render times.

 

My technique for faking is as follows:

 

First place a light simulating the sky outside the window using inverse falloff. Next add an ambient only omni light in the center of the room also using falloff, colour according to the rooms atmosphere.

 

Now I have found that using diffuse lights outside the model help give that gi look because as you know ambient lights tend to make renders look flat. So in this case one bellow the floor illuminating the celling and walls is enough (don't forget falloff). Add some diffuse omni lights inside as necessary and add an area light casting shadows only for the floor and objects.

 

Use ambient occlusion to help with indirect shadows, I made the mistake of overusing it in the past and relied to heavily on it for my fakes.

 

I hope this helps.

[STRAT]

have you tired attenuation (far clipping) on your lights instead of falloff, out of interest? the general way of thinking is to use falloff on lights, but i find it a tad too harsh. Far clipping is much more subtle and softer i.m.o.

[sdds]

thanks for the tip strat, I will try it now
