Rayrace mode issue Front and Right views


Rayrace_mode_issue_Frontt_and_Right_views.3dm (264.2 KB)

I am having a Raytrace mode problem where only in the Front and Right viewports the object will not render and then pans out of the viewport down and to the left.
The Viewport Layout is not set to anything custom just the “standard” 4 viewports.
At first I thought this behavior was only occurring with somewhat more complex geometry / objects but then I tried this simple uploaded model and the same phenomenon occurred Below are some sequential screen shots of what happens and some some system information.

Resting the Viewport Layout back to 4 viewports:

The series of events would repeat.

I checked the file the best I know to do and it looks fine.

My system information is:

Thank you for any help.


This has already been fixed in 7.10

Hello Nathan,

Thank you but has 7.10 been released for download yet?

Thank you,


It is available in the Service Release Candidate channel.

Hello Nathan,

Yes, installing the 7.10 fixed the problem.

Thank you so much. I appreciate the help and in your getting back to me so quickly. The GPU and CPU do seem to be working pretty hard though.

Thank you,


Well yes, you’re doing no fewer than 4 viewports in Raytraced mode.

I hardly ever do that myself. I mostly have just one viewport in Raytraced mode, but if you need to have them all in Raytraced you definitely shoud (:

Yes, sometimes it helps me see what is going on and what might need to be done to improve the design. I just thought that the complexity of the model and file size of the model had more to do with causing the system to work harder and was surprised to see the system working as hard as it was with such a simple and small file size model.
