3DS Max - Print Setting at 300DPI
show user profile  Landia
I just did a test rendered with Vray and it took about 1:20 minutes for an image size 34" x 23" (300dpi resolution). Is that a good amount of time to render a very large size image?

Here is the thing. When I opened the image that I just rendered in 3DS Max and opened it in Photoshop. The image Size and Resolution got REALLY HUGE (93.75" x 141.667" at 72dpi Resolution)! When I set the size in 3DS Max, I entered image size of 34" x 23" at 300dpi resolution. Anyone know why Photoshop is showing a much larger image size?

In Photoshop, I was able to change the image size back to 34" x 23" at 300dpi resolution. But is that the correct way to properly use 3DS Max image size setting for Printing?

So the procedure to setup print image in 3DS Max:

1. Set the printing size at 34" x 23" inches and Resolution at 300dpi.

2. Take the rendered image from 3DS Max and open in Photoshop and CHANGE BACK the image size to 34" x 23" inches and set the Resolution at 300dpi.

Thanks for any advice!

Work out the number of pixels you need. Render that.

That is what I did but Photoshop is showing me a much larger image size and only 72 dpi resolution.

So here is what I put in render size in 3DS Max:

34" (10,200) x 23" (6,900) at 300 dpi.

More importantly, grasp an understanding of what you're talking about since you're doing things the hard way to get to an easy solution.

I sent the image to the print shop and they approved the image quality.

However, it does not solve the issue why 3DS Max render the image size that is larger than what I entered. I change the image size by going Rendering > Print Size Assistant and enter these settings:

Chose DPI Value: 300

Paper Width: 24"

Paper Height: 34"

And I click the Render button. Once the render image is done, I should get exactly what I entered above but I am not getting those results. I should not need an additional software like Photoshop to play around with the image size and resolution.

So I think 3DS Max 2016 may have a bug in their software.

Don't do anything with DPI and inches in Max. Render the pixels you need as you calculated above. This will give you the correct size image.

Now we are getting somewhere. I will give that a try today.

Thanks Nik!

Under the Print Size Assistant, I should set the DPI to "0". And all I have to enter are these 2 numbers:

Image Width: 6,900

Image Height: 10,200

When I entered those 2 numbers above, the LEFT side numbers are showing something different:

Paper Width: 10000.0

Paper Height: 10000.0

DPI: 0

Is that correct?

Okay, I just tried the new method and it did not work. The image rendered at 72 DPI again.

Back to Photoshop.

Thanks everyone for advice anyway.

"So I think 3DS Max 2016 may have a bug in their software."

It's not the software, it's you.

Nothing personal, but I would guess you don't know where or why the number of 72 DPI exists?

To sum it up.

72dpi is what your screen is. Ignore that totally.

10,200 x 6,900 has no dpi. It just is. Pixels are pixels.

Give that to a printer and tell them it's 300 dpi and your print should be 34 x 32 inches.

Thanks Nik, I will give that size and see if they complain about the size and resolution.

I have another quick question about rendering with Vray. Is there a way to make the settings to improve the edginess of the render image? There are a few areas that is showing edginess and not smooth out. Especially on curvy shapes and diagonal shapes.

Thanks everyone for your advice even if I don't understand what you guys are talking about. :-)

'edginess'? either you mean faceting or you mean antialiasing.
You need to do some training on Vray to learn about the engine itself. From what your post suggests your image is very basic if it only took 1min 20 sec to render an image that huge. Can you post the image so we can see what problems you are experiencing since you're not familiar with the terminology?

Don't post it full size whatever you do :)

Youll need to upload it to an external host and post the link here;

this is a good place to start.
