vray like renders ?


#1

i noticed many great car renders are done with Max and rendered in Vray. HEre is a good example:

how can you achieve this in cinema 4d ? is it basically good materials, good light setup and good use of hdr ? any tips on lighting car scenes in c4d would help


#2

you pretty much said it. just talent, skill and persistance. cinema render engine is just as capable of producing this stuff, it’s down to the users. also don’t forget post work.


#3

one quick one… max uses chamfer what is the c4d equivalent ? is there a chamfer plugin for c4d ? thx


#4

it’s a case of using edge bevel multiple times to create a smooth chamfer in cinema currently i’m afraid, though you could also use hypernurbs edge weighting provided you’ve set up your objects mesh well enough. the only full curved chamfer command in cinema tht i know of is the one for splines.


#5

hopeully v9 will have chamfer and also cap command like in max will come in handy; i assume modo will have all these tools


#6

don’t assume that it can’t be done.

Funny thing is that this thread reminds me of one I saw I while back in the Maya forum. The guy was asking how he could get C4D quality renderings out of Mental Ray . Funny how people assume that the renderer does all the work…I wish :smiley:


#8

i never said I assume the render can’t be done, read my post again
I still wanted to know if there is a cap command so I build something and now I need to cap it like in Max ?


#9

use the make polygon tool.or even the bridge tool to close the hole. alternative routes that you could try are also to convert the edge of teh hole to a spline and use the extrude nurbs obejct to make a cap (then make that editable and connect to your other geometry).

As a hardcore user of C4D i’m very sorry to say that vray produces much better results than C4D renderer…
After endless tests i had to admit it and i’m using vray for all my architectural interiors now.
You won’t find anyone who hates 3dsmax more than me, but the final results made me go for it.
I can post an example of a room i was working on. I have some images made in vray, maybe some of you would like to try to achieve the same results in C4D, as i did without success…


#11

hey twilight
I would like to see that and give it a go.I have just about every 3d program
(3ds,maya,lightwave,cinema 4d)Ill try and reproduce the results post the pic :thumbsup:


#12

try using an unblurred HDRI in vray, and try the same thing in C4D, then come back and tell me about your experience :wink: However i’ll be happy to try your scene, post it as soon as possible! :slight_smile:


#13

we did this before…not that i can remember the conclusions…but can’t remember it not being possible.
see old threads.

not convinced its not possible…but then i don’t know a great deal about vray so its always up for debate i recon.


#14

Debates like this will always happen.Some people take it to far as thinking that others are crapping on cinema.I love to compare i think cinema can do renders like vray but sometimes its just a little more work.Comparing and debating is good how do you think things change.Bring on the test :thumbsup:

Don’t get me wrong. I still use C4D for 80% of all my work. Where i think vray is better than C4D is in architectural interiors (where i don’t use hdri). Somehow the radiosity “feel” of vray looks better than C4D…

Here’s an image of the interior i’m talking about (keep in mind this is my first vray experience):

And here’s the C4D scene. Some things have changed, but it’s similar enough for this purpose:

http://www.streetdogstudio.com/temp/room.zip

There are no lights on the C4D file, so feel free to try any approach.
The vray file has a very simple lighting setup:
One direct light to simulate the sun (same as c4d’s parallel spot)
One vray light in each window acting as portals. Portals are supposed to “drag” the light inside the room, and that’s pretty much what they do. The nearest thing to a portal in C4D is an area light, but it won’t “drag” light inside the room…

The rendering times in vray can vary a lot depending on the settings. For the test images i was getting times under 10 minutes. The final image above took about 1 hour to render at 800x600 but it took about 26 hours to render at 1600x1200 with the appropriate settings for that resolution.

Notice that there are very few artifacts, even with such a simple light setup. Also notice the overall atmosphere, it looks like you can feel the light inside the room.
One thing that puzzled me: vray darkens the corners while C4D lightens them. I never understood why, but i like dark corners, it somehow looks more real.

Final note:
I’m not a master at C4D or Vray and I’m not jumping from software to software every week, but i have to keep in mind that my clients don’t care if i work with software A, B or Z… they care about the final results, and right now i’m getting better results with vray than i was getting with C4D.
Also, most of my rival companies are using vray and they are getting better results than mine… i can’t keep that up.
Maybe it’s just me, maybe i’m doing it wrong in C4D. That’s why i’m sharing the scene with you guys. I hope you get better results than me because i’d love to keep using C4D.

Sorry for the portuguese names on the objects and materials, i never thought this would go public.
Good luck and feel free to keep all the meshes and textures.

very cool ill give it a go.I agree with what your saying about the corners
and how a lot of people are using vray and getting great results.Well thanks for sharing :slight_smile:


#17

Very cool twighlight! I’ll be sure to post some of my results and settings if I make a go of it. :thumbsup:


#18

Wow thanks for sharing that. It realy is a beaughtiful render. I will work on this tonight. I read the other threads to. Its good we can all discuss this without flaming everyone and closing our minds to the possibility that another renderer might be better. A few questions that will seem pretty dumb but i will ask anyway. How do you go back and forth form 3dsmax to c4d (format)? And is theyre any way to render in vray w/o max? I think to the latter question their is no way but thought id ask w/ hope that i am wrong. Thanks again. Vray is very impressive and its good to discuss this. Maybe theyre are some things maxon could do to adjust the gi renderer but first we have to get to the core things that make c4d renders or vray renders beter in certain areas.

Oh and since were comparing could we see a render in vray of this scene as it is included in the file and a comparable c4d light setup. I got frustrated pretty fast trying to recreate that lighting. Thanks again.

@BESTrin

How do you go back and forth form 3dsmax to c4d (format)?
There is no easy way to transfer models from C4D to 3dsmax or the other way around. 3ds is the most obvious format but it triangulates all the geometry, which bothers me a lot!
3dsmax doesn’t support the .obj format but there are some free plugins out there for 3dsmax 5 and 6 for that. The .obj format works great but it has some problems with the normals. You might have to align all the normals in C4D to get them right in 3dsmax. Even though, some objects will come into 3dsmax with flipped normals. I’ve got used to apply the ‘normal’ and ‘smooth’ modifier to every object as soon as they get into 3dsmax. There’s no easy way here, just a lot of patient.
Another way to do it is to export from C4D in .dxf format, open it in autocad, save it as .dwg and import it into 3dsmax. Version 6 reads dwgs perfectly without triangulation.

And is theyre any way to render in vray w/o max?
Nope. Not yet. Chaos group (makers of vray) are talking about a standalone version of vray for ages, but i wouldn’t count on it. Those guys have a reputation on delaying deadlines… Version 1.5 of vray is awaited for almost an year now.
If it comes out as expected, version 1.5 will be released shortly followed by a Maya version and a standalone version. I think it will be easy enough to write a plugin to connect C4D to the standalone version, i hope so, but it can take a long time before that version is released.

Oh and since were comparing could we see a render in vray of this scene as it is included in the file and a comparable c4d light setup.
I’m not sure i understand what you mean. The image is a vray render. The lighting setup is pretty easy, just a direct light for the sun and some vray lights (portals) by the windows to drag light inside the room.
Since C4D doesn’t work with portals i’d use a direct light for the sun and some omni lights by the windows (?)…
I forgot to mention that i also have a self-iluminated material on the lamps, but that doesn’t make a big difference.

Nice to see people having a go at this. Keep it up.
Thanks!

P.s.: I love the new CGTalk format!! After posting this message i’ve found this one on the related topics:

This is your mistake!!

Try with different type of light!

Vray renders are all the same; flat with some dark on the corners…

This is one of my test with C4D.
