HDRI control

[ura]

I need to synchronize the camera with HDRI.
The picture environment map does not match the model. Reflections on the model are incorrect.

in this video you can see how HDRI corresponds to the model

I will try to explain more clearly.

The default is obtained such a scale environment map. I need them the object looks like a little toy.

In the settings I can change the scale to an acceptable level. Environment Map is distorted.

If I understand correctly, you should scale your object instead of the environment map. Or just simply move the camera closer if you can.

show a better example in Arion render, all at once will understand, и добавочно напиши на русском подробно , в команде много русскоязычных програмистов, они поймут

И еще раз попытаюсь объяснить чего же мне очень сильно не хватает.
Мне нужно настроить отражения интерьера в мебели. Когда вставляю карту отражения, мебель получается игрушечного размера. Получается как будь то у камеры угол зрения допустим 50градусов а в ХДРке градусов 5 или 10.

Есть возможность уменьшить размер самой карты, до приемлемого. Но при этом виртуальная сфера остается такой же огромной, а карта с окружением многократно дублируется. Ничего хорошего опять не получается.

I changed the scale of the object settings in octane. It did not help. I tried to increase the facility is 1,000 times. The result is the same.

Here it is seen that when the camera angle more than 100 degrees, the environment map scale turns good.

Hi There,

I think is confusing HDRI usually are use at latlong format so spherical , Octane use as spherical , other softs use sometimes cube or dome... anyway all this options is just to have a average of the reflection because you have to shoot your HDRI at place to get a "perfect reflection".

My advise to you is create like everyone does at this industry feature films or advertising, You have to project you hdri at your custom shape . For example create a quick cube as the room shape and project on the custom shape as spherical projection if your HDRI are on latlong format, You should have the right reflections for that. but again this is "lighting Technics" nothing to do it with Octane but of course this way you loose the importance sampling from the sunsky node. but you can also use the sunsky to emit light and then for the reflection use the custom shape.

From Otoy side we could ask to make have a option to add a custom shape (mesh) at sunsky node for example cube, dome or other so if is possible use importance sampling on them.???

Hope this could help you.

example the famous scene for Ironman images attached

Necessary setting environment sphere size.

this can be done by hand. then cut and merge layers in Photoshop. But why this complex structure, when only one arm? BDSM?

Watch a video with Arion Render.

Нужна регулировка только одного параметра. Это или размер сферы окружения, или угол зрения камеры внутри нее. В противном случае, простая работа превращается в крайне сложную В моем случае совершенно не рентабельную.

The only thing about Arion video, is the dome environment with the shadow cast like V-red, V-ray and other render engines is nothing special about " reflections" there, because usually dome environment for car is the best result specially for the reflection of the ground on the car body.

The images you have post is about reflection? right? This is the reason to create a special environment to match the reflection you need, anyway maybe I didn't understand the actually question?

Best,
JO

Thank you for the video. But it is not clear how it works.
When I just twist the scene. I get to achieve the appropriate scale, only an increase in the angle of view of the camera 115 degrees.
