Title: Corona Frame buffer not 1:1
Post by: slowgojoe on 2019-06-24, 23:18:53

Hi, I'm working on a 4k monitor and it seems that the frame buffer is not showing a true 1:1 size for the screen. Vray frame buffer works as intended but Corona frame buffer looks to be zoomed by a factor of 2.  Any idea of how to fix this?

The attached screencaps show vray vs corona with interactive rendering running at about the same size. You can see the difference in the displayed resolutions at the top of the frame buffer.

Thanks for the help.

Nevermind. As luck would have it, immediately after posting, i found the solution myself.

In Corona System Settings, under the "Interactive rendering" category, the "Image upscaling factor:" was set to 2 rather than 1.

Problem solved.

Hi,

Yeah this is a new feature of v4. I'm glad you already found the setting to change :)

Thanks,

Rowan

Speaking of, does this feature exist in Corona for C4D? Because C4D doesn't really have a good way to scale for High dpi monitors, the frame buffer is always 1.5:1 anyway (if you let windows scale to 150%).. it would be nice to be able to scale it independently so i can get a true 1:1 result.. but i imagine that's may be more difficult to implement than it sounds.

anyway, thanks for the response!
