1) The model built in AutoCAD (MAX> Import ...) 2) Appointed HDR-file: Rendering menu> Environment> Environment Map ...> Material / Map Browser> VRayHDRI (then dragged into the Material Editor, set up) 3) Appointed windows (and the gate ๐Ÿ™‚ - for clarity) Vray material from the "high reflection." 4) After the render this image: - Any nonsense with reflections. - Any nonsense with the background. BUT! If you create any object, for example. scope, and assigns it the same material as the windows, then it will be a normal reflection HDR pictures !!! Tried options with UVW Mapping (usually after AutoCAD is necessary on all imported it must appoint) - no result ... Of course, it is better to see once ... archive model ps big request to respond. Thank you.

Hello, Yuriy E! Apparently (or rather by your renderer and type bekgraunda), you have a poor quality HDRka blurred. That's all. Look for a house, you can see it in exactly the form in which it is, no better - or worse. This is the principle of the Environment background. Why is the area she looks better? Briefly - because a sphere, due to its shape, reflects much of the HDRI, than in the window plane. Look carefully and you will see that the window is visible only a small part of the backgrounds, melenky his piece, and to smooth the area, it is recognized almost half Background HDRI. If you render a higher resolution image, and then go over to the scope and attention to the reflection on it, the same piece of the HDRI, which is visible in the window behind it, will look as dull and blurry, simply because you have such a HDRI. In the field of the environment is reflected larger than the plane, while comparable amounts of both figures. Therefore, every detail of the HDRI, reflected on the sphere, just smaller and create the illusion of greater clarity and sharpness. Create a sphere the size of a house, or twice as much, so that only part of it fell into a frame, and render. Then you will see it is not the whole area (hemisphere), but only the Greatest part of its surface, and seen to be a reflection of you in the same blurred as the plane ๐Ÿ™„ Pure geometry, not a CG ๐Ÿ™‚

Hello, denny. In fact, it is trivial. HDRI must be just so, what you need. That is, it is a quality that suits you. Find HDRI with your desired theme (environment) and large enough in comparison to the final resolution of your render resolution๐Ÿ˜‰ View looks like this or that HDR image, you can, throwing it into Photoshop, or using imeydzh vyuvera. For example, XnView can view HDR images. By the way, besides the possibility to view the HDRI, another significant advantage of XnView it is that it is completely free and you can easily download this free viewer from the website of its developer ๐Ÿ˜‰

Good day! I had a primitive problem, I do not see in the Material / Map Browser VRayHDRI (max2011 + VRay2.10.01). In the scene from 1 post I see a corresponding mat with the settings and assign a new standard of fails. What's my mistake?

Hello!

Check which render you should default .
In particular Material Editor, to be V-Ray.

Thank you! With renderer everything is OK. "The method of scientific spear" I found in the Material -> Get Matirial sought me. It remains unclear the difference in purpose of the material by pressing the button Standard and through Get Matirial I think it will clarify the materiel. Thanks for the help! Do I think I will come back ๐Ÿ™‚ Special thanks for the article on Vray, read soon!

Viktor using Get Matirial minute mozhesh vibrat not only material, but also the procedural card. and only the material during Standard.

Ellesar, just sitting reading, but it is only a general description goes. Thank you for elucidation !! ๐Ÿ˜‰

Yes nezachto ๐Ÿ™‚ just remember that Get matirial material more versatile if I may say so) If you use the material vraymtl, blend, and so it can safely vibiraem them from the Standard, but if you want to map as a procedural vraysky, VrayHDRI and others that they need via the Get vibiraem matirial ๐Ÿ‘Œ good luck)

Hello. Faced with such a problem. Why is it when rendering the scene HDRI reflection I appear only on a spherical surface, while on planes when they are not present at all. Please help me understand this voppros. Thank you in advance!

Hello!

reflection type, depends on the shape and loyalty smoothing of the object, reflection on which you watch. That is why, in your stage HDRI no reflection on planar surfaces.

First, carefully read this discussion, then essentially contains the answer to your question, as well as see the topic about the kind of material anisotropic stainless steel on the smoothed object is not true, as well as on-site which is smoothed correctly๐Ÿ˜‰

Hello! Please tell me how to manage settings HDRI Mercator map is used as the Enviroment and reflectionrefraction enviroment override. This refers to the picture itself is large and smeared. And also reflections. Mozhnoli customize it to your liking? In the editor, with material options are no such. I use 3ds Max 2012 and Vray 2.0. Thank you so much!!!

Hello! Dragging the card slot of the Enviroment and toss it into a free ball in the Material Editor Instance mode. Then, right in the Material Editor and control card. And also please read this thread๐Ÿ˜‰

Good afternoon! I would like to continue the conversation about the quality HDRI. I downloaded the library HDRI Dosch design. One HDRI-LL file is 5 mb. I was not satisfied with the quality of cloud nor small nor large renderers. Clouds without a lot of flat-shades-colored, not clear: file HDRI: Tell me not to act where brute force search for high-quality HDRI, bibliotki name HDRI and just about enough file size. Or I have another problem? Oseschenie-vraydome (with HDRI and Well in enviropment) and vraysun. I read on another forum thread that clouds can be inserted in Photoshop, but if I have a complex of buildings and the need 5-6 pictures from different angles do not want to raise a job yet and photoshop ๐Ÿ™‚ hotelos to hear the opinion of the practitioner ekstererschika ๐Ÿ™‚ Thank you very much! And another question for, it is not the case, but it is very topical ๐Ÿ™‚ In a collection of models can be vines, I need here such or similar. Evermotion download several volumes, but has not yet found hanging. If someone tells the name of the library or lay, I will be eternally grateful ๐Ÿ™‚

Daria I do not know any more appropriate. But only I opened this topic. In the background is better to use ordinary background image in normal quality, just inserting them into the shop in the alpha channel, the latter is easy to do even in the finished project plugin RenderMask, it's free. And always use HDRI as a basis for creating reflections on the objects, and can also be a good approach as the main source of lighting scenes. Liana, I would have done as a plugin, called Ivy Generator, also completely free. Online lessons on them are many, do not get lost. Regarding collections HDRI: I like the cards from Viz-People and Viz-Park, there is everything you need for a good visa, both day and evening, cloudy, and the like, even at night. The quality of them is excellent. Find those, too, is not an unreasonable difficulty๐Ÿ™‚ Good renders all!)
