Realistic Rendering

[OutCold |]

Before i say anything else i want you too know im a semi noob at rendering...


Im working with a Chrysler 300 atm wich was made by Dosch and i decided too remodel alot of the parts in addition too adding objects too the car, im doing this purely for training purposes and this car wont be realeased in any way since it is a Dosch Design model base, ( didnt look like a 300 thou :P)

I got some trouble making my HDRI work the way i want it too, but that another chapter, i was wondering if anyone here is doing their render in Vray?

I was hoping Vray had something similar too Brazil`s CSG Server wich allows u too kinda place the car in an 3d environment created by a simple bitmap picture in the env slot , or if there are anyone that know another way too cheat my way into a realistic render with a real background?

Thnx

That might be a good tutorial to look over if you're using Brazil in 3D Max. It's what I used to learn how to create and use HDRI environments. Pretty helpful tutorial there.

i know Brazil in and out man but thnx ;) , i was wondering if it was possible getting some similar results in Vray...

so u simply want to render ur car with a hdri as background?

Just put it in the enviroment slot!..

Well , you don't really need HDRIs to make good looking renders , i made this pictures with only a Low Dynamic Range picture (JPG) and nothing else ..

But if you are going to use a hdri , simply putting it into the environment slot will not get you the results you won't (unless it's a coincedence ) , first you have to adjust the HDRI position inside 3dsMax so the Reflections on the car would match the background , i don't like hdris myself :D and i'd rather use normal JPEGs , it's up to you to choose .

its not about hdri , ok hehe look guys, i dont think i have been explaining this very good apparently, its not about hdri or brazil, its simply about how i might get a csg server effect with Vray on a normal picture background, the keyword here is similar shading like the Brazil engine produces..

[instinct-vfx]

I still dont get what you mean by "csg server" csg means "constructive solid geometry" wich has nothing to do with rendering...you got me confused there.

ye same here?:clown:

LOL! like i said i was a semi noob, u know the way u can place an object onto a jpg (whatever) in the enviroment slot and it will be embroided into the environment as if it was a real picture ..

man , that's a composition , it's not made with a specific render engine , any renderer , any 3d software can do that ,whatever you are using now ,look in the help files and documents and i'm sure you'll find a way out :)

[if you are using MentalRay , i'll show you how to do it with a small video]

i can see he says he uses jpg pictures too make those renders, but nothing about how :p i am using a jpg too,
if i slap my model on a pictue in my env slot now it just puts the model as if it was stuck on the pic, i can get the same result in photoshop, if i have a picture off tarmac wich i place there the model produce no shadows in cooperation with the picture too make it look like its implemented in the picture, not just slapped in.

U can see some examples under here, i used a normal grey picture as a background in the first wich is a BRAZIL render, the second picture is a VRAY render and u can see it looks just slapped into the picture without any shadows that indicate its position in the picture.. DAMNu guys are fast, u posted all that while i was writing this one haha , let me read back abit

[Dave_3d]

I think you just need to add a matte plane to catch reflections and still let through the background. Don't know the settings in Vray for that.

And, of course, match your lighting for shadow fall etc.

Does it matter wich engine i use if its not about the render engine? will the vid give me any tips on how too proceed in vray also? , i mean are there any similar settings?

[OutCold |]

Omg Guys Slow Down Hahahaha ur talking too a total greenie, let me try a few things after reading back on your posts and ill ge t back too you, thnx guys

So i should put Matte/Shadow in the env tab and not as a material on a plane? cause thats what i did, ( mat on plane) in the second render up there

[Dave_3d]

Have a quick look here :

That gives you the basic background for compositing. It is for Mental Ray but the principle is the same in any renderer.

OutCold | ------> you had to load the picture again?!! :D

you are right , a JPEG acts exactly like a HDR if you set the correct amount of RGB and output amount , of course HDRs come more handy when they are warped (this is general discussion , right ?? or are we intruding on the thread?)

As I said, I don't use Vray - maybe someone with Vray knowledge could reply ?

But you need a plane there. Not only for shadows, but if you are using GI especially, as you should NOT receive lots of lighting from underneath.

Lol yeah i f`d up and put in the wrong picture, and no, please enlighten me. doing a render now where ive setup a light with shadows onto a groundpane with an env in the background but it looks like its coming out the same way :(

[OutCold |]

EUREKA!! some adjustments needed of course... :D

[OutCold |]

:angry: Something happened too my UI and im not able too get it back too normal dark ui, is there anywhere i can dl custom UI`s that might help me?

[petter]

do you want the default dark UI ?
just reload it from Customize menu...

[OutCold |]

Doesnt work, i think ive messed up some setting or something, doesnt really matter i can just replace the files in my UI folder with fresh default ones right?

About Material ID`s : Does an object take upon the material id of an overall selection or does it take upon the settings of the material id in only that material branch , im using multi submats..

[OutCold |]

Got it working again

[Dave_3d]

Well, for the help of everyone else, care to share what you did and what your problem was ? Leaving it at "I found it" - helps no-one.

People took the time to help you earlier.

And no need to swear.

Dave

[OutCold |]

lol im so sry i was drunk and my temper was deterioated by this problem, i think i set some colour adjustments wrong in the configurable UI , i just replaced ALL the files in my directory and it reverted too the normal colours, again im so sry for my last comment...

[petter]

heh...:clown:
at least you solved your problem...

[OutCold |]

yep, thnx bro

[Dave_3d]

Thanks for letting us know.
