In rhino7 within the render options you could manually change the dpi output but in the rhino8 rendering options it doesn’t appear to have that option. I’d like to increase the render output, has anyone found a way to do this?
Hi Jared - I see that difference, thanks, I’ll check.
@Jared_Gray_IV - how do you use this setting in V7? What does it do for the saved image?
-Pascal
In V7 I go into the rendering settings within the right side panel and would be able to manually type a value into the DPI output and it changes the resolution of the image (the higher the DPI the higher the level of detail will be within the render)
Hi Jared - yep, I understand how you get there, the question is why? You can set the image size directly to however many pixels you like, for higher or lower resolution.
DPI is a bit of meta data that can go on the saved image to provide a physical size for a printer, for example, but if you are not using this in the saved image, it is best and clearest to set the pixel dimensions directly. (That said, I do not yet know why the setting was removed - it seems harmless enough and occasionally useful.)
-Pascal
I was attempting to put a higher value in because my renders at all the highest settings still weren’t coming out very clear (attempting to render a complex mesh)
Hi Jared - what is the size shown in pixels?
-Pascal
The dimensions is the size in pixels but I was attempting to increase the resolution which I believe is a reflection of the DPI value (was looking for 500x500 resolution)
Hi Jared - that pixel size is probably plenty - you see that you can make it whatever you want though in Rhino? Keep in mind that what counts is the number of pixels, not what the ‘dpi’ says.
That said, what I see in your image ilooks like a moiré pattern where the grid of the fence is mixing with the grid of pixels on the screen.
If you look at that image full size, does that still happen? My guess its it will change according to how zoomed in to the image your view is.

ok noted, thank you for the clarification and yes I do see that
I attached the image, in full screen it loses the Moire pattern
Unrelated but still concerning this image, I attempted to put lights in the hallway adjacent to the “fence” in order to have the shadows cast onto the stairs- what did I do wrong that they are not showing?
also what is the best way to get the render settings right
Hi Jared - post here, if not confidential, or send to tech@mcneel.com, the file and I’ll have a look. Please put a link baack to this topic in your notes to tech.

Hi Pascal,
The file is really big (870 MB) how would you recommend uploading it?
-Jared
Hi Jared - SaveSmall, (probably important in this case), zip the result , and upload to Rhino - Upload to Support to my attention…

Hi Pascal,
I am usign Rhino 8 on a Windows 11 PC but I have the same problem.
What Jared said is true. In fact I actually need to have renderigns for a design competiotion very soon and I need to have specific resolution for them.
I should be able to choose different types of DPI resolution for the same size of a rendering. For example, I can have an image with the size of 40cm x 40cm with 72 DPI or 150 DPI or 300 DPI… the size would be the same but the number of pixels in those dimensions in will be different. An image 40cmx40cm with 300 DPI will be much cleaner and high resolution than one with 40x40 cm and 300 DPI. Does it make sense?
In fact I could do that in Rhino 7, now i can’t. I cannot choose nor the DPI resolution nor the size of the rendering in other dimensions (for example millimeters or centimeters)…
To me is a big problem and a wastee of tmie as i have to open the renderigns in other programs and make the transformation.
Can we solve this?
Thank you,
Eleonora
You have no idea what you are talking about or what DPI even is… Can someone else please respond or you will definitely loose another customer.
I created a plug-in RhiPPI, you can search for it on the plug-in manager.
Once the plug-in is enabled you can add a new panel PPI to a container.
You can set the size in millimeters and adjust the PPI.
Note, you have to use the Render button in this panel, it is needed to ensure that the final result has the actual PPI info saved.
I haven’t tested it much on the Mac, but a quick test showed it should work.

Thanks for this plugin Nathan.
It’s not clear to me what does Default render location stand for ?
Is that the location where the render results are saved?
Yes, the plug-in will save to the selected folder and with the file name with 3dm replaced with png.
If the file has never been saved before the name of the rendered image will be UnsavedRhinoDoc.png
Hallo, I am sorry but can’t find RhiPPI anywhere in the plug-in manager on a Windows machine. Where is it hidden??
You need to install it via the package manager, @Jan_Goedbloed
