Hope that helps ;)

I think it has a couple more there.

just go to google and type in HDR or HDRI and you;ll find hundres, I have a husge collection well over 200 HDR images now

[Claudio72]

I've already do that Kai, but it takes too long to choose into the site, many time there's only an example jpg.

In the images search, nothing interesting comes......



I don't know, if you zip your collection it would be nice to download

[VestanPance]

Man that would be HUGE! Some HRD files are around 2 MB...zipped.

[Claudio72]

if kai has the console of a machine in internet I don't have problem downloading any quantity of GB, also at slow speed.


:D

[LucentDreams]

If I had permission to supply them I would, I'll look into compiling a list of some of the sites I got them from. And yes it is huge, which is why users should also push maxon to support OpenEXR, which is similar in quality (almost always equal in quality) but far smaller file sizes. currently my HDRI folder is 197 megs, but I have alot of HDRI to convert, and a small group of like 50 are only 512x512 :( not ideal for sky illumination, so they are almost useless. course none are that great until C4D gets HDRI fully supported, otherwise they are just like anyother image.

hum..hum... i´m sorry folks, bUt exactly is HDRI?

oh thank's, this one rule!!

how do you use on the sky the spherical hdri images??

If I put it in spherical projection I've an hole side the sky that produce an hugly reflection............are those kind of images not good for hdri lighting??

[VestanPance]

Use HDR Shop and.....Follow this tutorial (http://www.debevec.org/HDRShop/tutorial/tutorial4.html)

If you are on a PC of course....;)

Here ya go!!!

A free plugin for Photoshop that does just what you are looking for.

on this site there are some images for a snowfield....this is what peoples ought to use for that wicked skidoo he made...would look cracking...

[Claudio72]

what does it change is v8 with HDRI? I know the HDR format is now supported, but what in fact changes? Do you still need the HDR shop/or the photoshop plug to resample the images? I think you don't have to lower the exposure in v8........is it true?

[LucentDreams]

currently in R8 if you open an HDR image in the texture slots in a C4D material, it loads using the same settings as the preview. its still only being used as a typical 8 bit image though.

your not getting the higher contrast and flexibilty because of the multiple exposures.

[Claudio72]

so you mean, it's possible to open an high dynamic range image but it's still necessary to perform the exposure tricks?

Did you already make some HDRI image by yourself?
I mean, 8/10 shoots of an env brought togheter in a single panoramic file?

[LucentDreams]

no, but I have a large collection of HDRI, and I'm a tester for C4D, and I can tell you right now R8 doesnot take advantage of the extra exposures. YOu can use a plugin for HDRshop to crate lights based on the lighting info, or you can output the different exposures and use multiple spheres to try and get the same effect, there is a great tutorial on how to fake HDRi already posted, but currently al C4D does is load the format and conveert it automatically. I believe this is to make room for HDRi later on, but only time will tell. For now all it lets you do is use and HDR image in C4D, but its no different than using a normal jpg.

[Claudio72]

got it :thumbsup:

[Claudio72]

for those of you interested in an HDRI premade scene there's one of my last test, I've used the well know kitchen.jpg.

If you want to download the zip(>3MB) and you're asking yourself why it's so heavy don't worry, there's inside one of my texture. It's the rough concrete texture.

Maybe I'm misunderstanding, but R8.1+ certainly does take advantage of the full 64 bits of data in an HDR. The only problem is if you put the image in an SLA shader (maybe others) it will be clamped to 8 bit values.

On february 25 there wasn't such thing as R8.1 ;)

Doh! It didn't even occur to me to check the date. Just thought you were sniffin' glue or something. :)

[kBg_Fiske]

Can you only work with hdri on PCs? All I have seen so far is hdri image progs for Win.
My apologies if this is a stupid question. :shrug:

[mikeh64]

hdri works in C4D 8.1 on all platforms, and the Mac equivilant of HDRshop is called PhotoSphere, and can be found at:

If that doesn't work just do a google search for "PhotoSphere"
