Brazil's Hdri On An Old Mustang

[ultrahelix]

Really nice model of that car. And for just 2 days of work even impressive. But you have to improve the scene, especially the ground looks not so good. The use of HDRI images in such a scene is a little bit strange, because the reflection on the car shows an outside scene with buildings !?

The reflection on the right windows are to strong.

But all in all the carmodel is very fine!

It looks like you're using a skylight with an extra light for that shadow. Try changing the light to an area light to get a softer shadow.

Looks cool. I have a '69 mustang, but it's never looked that clean. :)

:beer: thanx for your pro replays to my thread
(FatAssasin - ultrahelix ).

the bigest problem s the unfriendly reflections for the HDRI on max but i'll try 2 improve em

... it´s a HRDI - there is no skylight!!!

Well, I'm not a professional HDRI expert, but I've been working with HDRI lately, and by the look of you shadows, I bet it's not from a HDR image....

The shadows are too crisp, pure standard raytraced like, I just can't imagine what HDR image could produce a shadow that crisp! Maybe an image with a single superb white pixel... Or a *really* big image, like 40000x20000px, but there you would have to use so many rays, I dont even think the max number (500) would be eneugh... :D

So, you didn't used skylight at all, so there can be no illumination from your HDRI, unless you've mapped it onto asomething, and have GI turned on, but I doubt that too, unless you've got a really cool PC, or renderfarm. :D

Using HDRI doesn't means that when you put your HDR map into the environment slot, you've got it all working, or not in Brazil.
If you want not just teh reflections, but the illumination based on your HDR map, you'll have to map it on the skylight, and therefore you'll have to turn skylight on.

I agree with FatAssasin about the lightning setup, You have to have a light source, like a point light, in you scene.

But after all this hard talk, the modell seems quite good, I really like old american cars, good job there! :)
I think after improvements on the scene, try posting it into the gallery, and next time, post threads with content like this into the WIP section,...
About the reflections: IMO the reflections look good, but there is that really strong white streak, is it the "sky" of the HDR map, or is that some kind of a super bright plane floating somewhere?
Really, you should do something about the lights, cause your key light is a bit crisp on the shadow side. Try using area lights, and some better environment, like a street, or some buildings modelled around the car would do wonders, thrust me! Right now, the environment map, the lightning, and the modelled environment lacks harmony.

Sorry if ' was a bit hard on you, I've just creeped out of bed... Yeah, thats good.
