How can i make a larger rendered image?

[markcrabbe01]

im hoping to make a good quality a2 Image from my work on revit however all the rendered images so far have only been jpeg format and only about 45kb.

this isn't good enough quality for a decent looking poster.

any help would be appreciated..

cheers

Mark.

You need to do two things.

1. Set the physical size of the 3D view to the desired output (ie: A2) - See Snap 1 + 2
2. In the rendering dialog, choose printer, and set the desired resolutin - See Snap 3

Note, that your printer modt likely can handle 600 dpi or more, but I seriously doubt that your computer can handle the rendering at that resolution. - I´ve never gone beyond A3 at 300 dpi´s

Have fun with it. :beer:

Forgot to mention:

When the rendering is done (Sometime next year ?) export it to a worthy format, PNG or TIFF (Note that the sky will then be in a seperate Alpha channel, for easy replacement in photoshop)
If you don´t want the seperate alpha channel, use a JPG at high or ´best quality settings...
Hope you have some killer hardware for that job !

I would start with the low render quality and then edit custom and turn up the anti-aliasing and any other specific settings as needed. Do some test renders at lower resolution so they look good. Running at high or best quality will take forever and you may run out of RAM before it's done.

Hi this is probably too late for you but if the scenes are large / whole exteriors or interiors with a lot of detail , and even with a quad and lots of memory, you will find there is no point going above 600 dpi and in fact, practically munkholm is right, 300 dpi is about it.

The mental ray implementation in Revit is crippled so that it is easy set up, fast to make lower quality renders, has few controls to worry about, no hassles with materials (see few controls) and no problems to deal with other than how slow it is to get a clean image out.
I know we complain about this however, the manufacturers have done a good job on making mr easy to use and that was part of the point - the other part seems to be that they want you to buy 3D Studio Max.
They are probably not going to give us anything better now so its time to look at the options.

Those options are probably Cinema 4D, Rhino, Artlantis Studio, Artlantis Render, Sketchup Pro (with a wide range of rendering engines to choose from that plug into SU Pro like VRay, Maxwell, Fryrender, SU Podium, Indigo (yay, made in NZ) and many others, such as Twilight .

You can also choose to run with a stand alone rendering solution such as Maxwell as it has Maxwell Studio built in so that non plug-in solutions can still work fine with the rendering engine.
Artlantis Studio is configured with this in mind I feel.

My choice has been to buy into Modo a couple of weeks back.
Around the same price as Artlantis Studio and functionally, has all of the tools you will ever need for arch viz as well as product design, advertising, modelling, gaming and so on with excellent suite of animation tools including camera rigging and a comprehensive suite of rendering and shader tools (which work a lot like Photoshop for masks) that you are sure to find mind boggling at a price that is 25% of Max and a company that seems to consider support and help a pleasure.

Of course, if you are not interested in generating animations where the doors, windows, faucets, door handles, books etc slide, pivot, drop, lift open etc., open you are probably better off with a stand alone rendering engine like Maxwell or Artlantis Render. They provide the same or similar level of rendering toolset without the animation toolset.

You can get a Revit model into modo as easy as any other package (at least at this point unless some anti-competitve behaviour comes along).
I would be happy to help beginners like myself, with any help I can in terms of start up (for Revit to modo workflow, initial camera rigging, basic animation process).
good luck

..... but if the scenes are large / whole exteriors or interiors with a lot of detail.....

Actually, the amount of detail/geometry doesn't really matter to mental ray. It's the materials used in the render and the number of lights that matter. Beyond that, mental ray takes the entire model into account when rendering unless you use a section box to trim out geometry outside of the rendering area.

Scott,
I agree, but note that the materials we can effectively use are actually quite limited and that is by design and is (effectively) a part of the overall implementation.
For a given scene, the higher resolutions mean more time but usually the pay off is just not there. For the additional benefit of going from 300 to 600 dpi, the time is large (related to the scene) whether you have the section box on or not.

I guess my point was (and still is) that for what the poster said he was after, I do not believe that Revit and mr are the (some of the right) tools for the job. If you want better quality you need to look outside Revit.
thanks.

....note that the materials we can effectively use are actually quite limited

The Pro Materials library that ships with Revit contains nearly 700 materials. Glass, wood, concrete, plastic, leather, paint, metals, and more. Each one of these materials can be modified to meet your specific needs by using custom images, colors, etc. Essentially, you can make any material you would ever need. Limitless....not limited.

Going from 300 dpi to 600 dpi increases the number of dots in a square inch from 90,000 to 360,000....quadruple the size. Also the file size itself would quadruple. So yes, performance will take a hit at a 600 dpi image size.

As far as the original poster's question, yes, he can get high quality images from Revit without having to resort to a 3rd party renderer, or without buying 3DS Max Design. There are definately some changes he needs to make to the render setting sf he's only getting 45kb images.
