When I go to do my final render I always set my render dimensions at 8" by 10" with resolution at 400. And it would render an Image at 3200 by 4000 at 8" By 10" with a 400 pixels per inch. Now with poser 12 it gives me a rendered image at 3200 by 4000 pixels at 44.444" By 55.556" with a resolution of 72 pixels per inch. Why is that, and how do I change it.
Thank you for any help David

This will bring up a little UI window where you can set dimensions and pixel pitch:

You can also bring up the render dimensions UI from render settings:

I hope someone will correct me if I am wrong but I don't think that Poser bothers about the DPI in this instance. I regularly render at 7016 X 2480 for printing a landscape picture across two A4 sheets. The reason I do that is an A4 picture printed at 300dpi is 3508 X 2480 dpi but note thet the dpi is only important when I have the picture printed.

??? I haven't printed anything in years. everything is digitally delivered and most don't have screen resolutions over standard HD. I nevrr look at DPI or PPI ever. That can be changed in your Photo editing software anyway and if the image is printed would be adjusted there.

Brian Haberlin works for print with Poser. He recommends 4k real-time Preview renders, and his Anomaly graphic novel page layouts (multiple renders, composited side-by-side) were made at 7,000px x 5,000px. Knowing how to crank the scene's Preview textures to 4096px, and the IBL Light shadow maps to 2048px, is probably as important as whether DPI is 150, 300 or 600, for that kind of comics work.

I know where to set the render dimensions and pixels, but poser 12 no longer renders at what I set it to. As I stated in my first post. How do I get it to render at the dimensions and pixels I set it for? Instead of a much much larger render with smaller pixels?

DPI refers to what a printer uses as how it prints an image. The concept of DPI for the most part is past history as all the printers I tried at work (I work in IT at a college) they just ask how you want the image laid out and they don't care about the DPI. Modern Printers (their drivers) will scale the image to fit whatever output you want.

I tested an image that is 1280x720 and the original file says it is @120DPI. I took that image into Photoshop and it says it is 1280x720 @ 72DPI. I copied the image to a blank image setup as 400 DPI and then it says it is 1280x720 @ 400DPI. I exported that image and the export does not list the DPI. I reloaded the saved image and it is 1280x720 @ 72DPI. The pixels are the same just some vague settings of DPI that changes.

What is it that you do that requires the image to say it is 400DPI? Since the printers I have only have 2 DPI setting 600x600 or 1200x1200 your image is either going to be output as pixels on a 1 to 1 basis so would be 400/600 or about 2/3's the size ~ 5.3x6.6 inches or the printer will scale it to 8x10. As I said above DPI is a past concept for the early days of computers when they didn't scale images and could only output 1x1 so you had to make the images to fit the printer you were going to use as your final output device. If you have a printer that is 400 DPI then your image of 3200x4000 should fit properly.

Not sure how we got onto printers, That is not what I am asking about. If I make a final render at 8"x 10" 3200 X 4000 Pixels at a resolution of 400 pixels per inch the image renders much sharper. So it does not look so pixelated. But with poser 12 when I set those parameters is does not render that size. It makes a massive image (44" x 55") at 72 pixels per inch. All I want if for poser 12 to render the image at the size I set like all the previous Poser programs did. How do I make that happen?

how to change dpi on a jpeg

It will point you to Irfanview. with it you will be able to change the DPI of your image. Since the number of pixels won't change it will shrink the apparent size of your image from 44x55 inches to 8x10 inches.

It still would be nice to know what it is that you do that requires the image to say 400DPI. since you say you don't know how we got on to the subject of printers and DPI is mostly limited to printers, what is it that you do? A computer monitor is fixed at what ever pixel pitch it is made with so thta can't be it.

a pixel, is a pixel, is a pixel. If you render an image at 3200x4000 pixels it DOES NOT MATTER WHAT THE SCALING IS. You will still have an image that is 3200x4000 weather it's "called" 72dpi or 400dpi. When you print either your software will scale it down to fit your paper medium, or give you a warning that the image wont fit with the scaling that it is set to. It won't lower the resolution of your image to fit the sheet of paper it just changes the scaling. Ignore the scaling in Poser. If you render 3200x4000 THAT IS WHAT YOU GET.

Ok, so instead of everyone lecturing me, Can anyone just answer the question as to how I get Poser 12 to render to the scale and pixels I set, like every every version of Poser before hand did? And I am sorry, but between 72 dpi and 400 dpi I can visually see the difference in quality of the render.

Ctrl-Y on Windows, or "Render Settings..." and:

Yup, did that, But it is not rendering to the values I put in there. I don't understand why.

Can't help you further, as 99.99999% if my pics are for the screen, and on very, very rare occasions, I'm scaling up the DPI with Photoshop, without even knowing if it does anything, and only if the target person specifically asks for it. As said before....

Did you asked the support?

Please report it, because this may be yet another bug. If what described above set the way it is described above results in not what you set it to be, it is a bug.

I went ahead and opened a ticket because it does indeed look like a bug. Both Poser 11 and Poser 12 create a correctly sized array of pixels based on the numbers entered in the "Render Dimensions" panel; whatever exports the image file in Poser 12 apparently isn't paying attention to these and calculates its own "physical size" based on the array size and the default number, 72 DPI. This won't affect anybody looking at the image on a monitor, but will affect anybody trying to print.

I literally just got power back yesterday after this winter storm, but will add a bug report myself after verifying it.

Issue was reported and I got a response indicating it is a known bug that will be addressed in future release.

Mine said it's been reported to the team for addressing in a future release. Ticket #000635, I think.
