No fair. Your image artifacts look like artistic brush strokes. Mine look like digital noise 
That's a very nice bit of modelling and lighting, there. You might want to try some of the free unbiased GI renderers out there, like Indigo (www.indigorenderer.com) or LuxRender ([link] ) -- I'd be interested to see what you would create. You're using C4D, right? I think there are exporters for C4D for Indigo. I'm not really familiar with C4D myself, so I can't help you with the image artifact problem -- though skimming the comments, it looks like others were able to help you out.

yeah we got it figured out their was area lights needed to fix the prob, i was using hdri only and that's what made it to that. i would need a better computer to operate a 3rd party though, just wait till i get my new computer im going to make stuff that's crazy, ive already modeled it im just waiting now lol, it would take weeks to do it on my computer cause its so freaking slow... but with a quad core ooo boy like hours lol.

Good stuff. I look forward to seeing what you produce when you get your new machine.
All the best.

I kinda like it, looks like a painting because of the artefact's

I look likes all you need to do is increase the number of photons and reduce their radii.

thanks...
the previous guy had a great tutorial that worked perfect and is now how i do most of my work for interiors.

Like siath said, smoothing. you can smooth out a few in PS, but idk 3D wise.
Great though, so real looking!

Are you talking about how its all speckled? If not ignore the rest of this. If so thats because of volumetrics. Thats inevitable and for the most part is ignored by deviantarts artists. thats why everyone thinks its awesome (which by the way it it. Very creative piece) My critique is that maybe you best option would be to take it into photoshop and fix it up, if you don't like it.

that kind of stuff it's produce for que GI, you have to add more bounces and change the shadowmap resolution
Maybe you have that much cuz you have irregulars poligons, if you did that windows with boleans, is probable that you made a lot of trianguls and when the bounces are calculated, can create that effect of brush strokes.
Sorry for my bad english

I have to agree with ~OneStripe , once you figure out how to fix the problem, remember how you did this because it looks artistic to me.

aside from the other lighting things that are specific to your program....the reason i found when i had shadows like that was because i didn't have high enough quality on the GI maps and whatnot.....also you should check your normals...if some of them are reversed then it will cause that weird coloring....second thing to check is whether you have faces on the inside of your object....like that can cause problems with smoothing which could lead to the blotchyness

I don't know why you'd need help, that looks pretty good =/
good enough for a fave

I won't repeat all the other good advice above. I will say that I think the artistic quality of this piece is excellent. If you don't like it, that is definitely your business, but I think it's rad.

Woah thats awesome! Thats the type of your art I like where you're inside of it. Cool mon.

BTW, if you don'd care about who does it, I 'd be glad to play with the scene on my end and give you back a .MAX file all set up and ready to render at full quality
PM me...

Seven, this is truly awesome... very creative.
I will toss in my two cents on your lighting.
Essentially, you need MORE LIGHT 
If using VRay, let me know... I can help with exact settings.
Another trick to use, if you don;t mind faking it, is to throw an OMNI in there and let it glow with a low setting and then increase it to taste. It will be invisible by default anyway
To help with VRay, increase the subdivisions and make your Irradiance maps BIGGER. Depending on your render output dimensions, you can play with the min/max values in the Irradiance Map.
I find that for deep dark shadow areas, Light Cache as my primary bounce estimator engine works great. But, it is not as EFFICIENT as Irradiance Map.
Brute force will always work, but it eats up CPU.
Finally, if you really don;t care about time to render, you can override pretty much ANY control in VRay by making the DMC sampler really high, I mean like 100 or more. This will essentially overpower every other dial in VRay and makes for very very smooth and correct renders. IT is just a brute force way to pump up everything at the cost of efficiency. It sure is easy.
But, it is NOT ALWAYS great. BE careful with really reflective surfaces that are rough... Chrome is not so bad but speckled metal shaders will kill your render as they have a lot of rays to bounce per pixel. Each bump is a hundred rays to calc.
Feel free to AIM me (I think is in my profile)
Cheers!

What's your renderer? Are you using area lights in addition to GI?
👍: 0 ⏩: 0
This actually does look really cool.
I'm pretty familiar with 3ds max.
What do you use?

Sorry but I do not operate the same 3d modelers/renders as you. I apologize for being unable to present assistance.

What your looking for is called 'smoothing'
But this does look interesting...

Oh wow. It looks like perfect brush strokes, not choppy with bad shadows! Obviously I have no idea how to help you with you '
