WARNING: Don’t set the image size in cm!

[Uhlhorn]

If You set the size of an image in cm instead of pixel, you will get in really big trouble! If you do not have the old values to go back exact the same way, then you have to reset modo completely!

In single steps:
My frame size was set to 4096 x 3048 with 300 dpi. I wanted to change the size to 30 cm x 30 cm.

• I set the „Resolution Unit“ to „Centimeters“.
  I changed the „Frame Width“ to 30
  I changed the „Hight“ to 30 too

From this moment beginning all my renderings were rendered only in half the hight (see screenshot).
I opened older files and other files, but only the upper half was rendering, the bottom half not, even in new blanc scenes.

I restarted the computer, I restarted the render client (a PC), nothing helped. But fortunately I was recording a screen cast. So I was able to get back step by step to get the old settings.
So, this is an really problematic bug! You should never never change the frame size per centimeter setting until this issue is fixed!

Hmm … now I can not reproduce it in a blanc scene. :-/

[Uhlhorn]

I see, that I was not able to get back. On square images (eg. 4096 x 4096) only the upper half image will render.
But when I save the image, it is in full size.

So, I have a view port problem now, because I have to render many images and I can not see the bottom half of the the images.

I couldn't reproduce this on Windows Modo10.1v1, or OSX Mdoo902. In both cases converting to cm worked as expected. I notice you are using network rendering - which I did not test. Also - the resolution in the status bar is showing 2048x1024, which is unrelated to the Modo resolution. What is your Kernel->Resolution tab showing? Do you have Use Modo Resolution ticked?

I reset Modo and played back the old preferences from Time Machine backup. I’ll try it later and give You a feedback.
Ah, and I got it on video, because I was making a screen cast. Perhaps this video will help You.

[Uhlhorn]

Paul, I sent You the video link per private message.

It could be that the zooming of the viewport isn't being recalculated when you change the Resolution Units like it does when you change the Frame Width/Height (which I will fix in the next release). Try rolling the mousebutton over the Viewport, and it should force this recalculation.

… Try rolling the mouse button …

You mean the mouse wheel, right?

… over the Viewport, …

Over which viewport? I have tried the render and the camera viewport. It does not help.
This problem came up again with only changing the width in pixel.

Hi - yes, the mouse wheel - sorry.

When you change the resolution, the centre point of the render bitmap appearing in the Octane Viewport changes, so you might need to hold the mouse wheel button down over the Octane Viewport window to pan back to the centre. But just mouse-wheel scrolling over the Octane Viewport should do it too.

The mouse wheel changes only the percent of view (Size, see screenshot), nothing else. I have tried the wheel, the pressed wheel while rolling, right mouse button + wheel, left mouse button + wheel, middle mouse button + wheel, shift + wheel, control + wheel, cmd + wheel and so on. But always the percentage is changing.
