I have read through previous posts on this, but, not clear to me as to how to resolve. In addition to the yellow triangle with exclamation mark, the viewport has gone to red. I can seem to be able to do anything with the viewport in red and will not update from the model.
Thank you. This did remove the red box/viewport, however, I have tried to update the model in LO and now another viewport on same page has the yellow triangle and exclamation mark. And viewport does not show updated scene from model.
FWIW, if you leave the viewports unlocked and the Auto render tick box in the SketchUp Model panel ticked, Those yellow exclamation marks shouldn’t show for very long when the reference is being updated. The yellow triangles will go away as soon as the viewports are rendered.
Thanks, though, not sure how this happened in the first place. As I have been working on this project for quite a long time and this is the first time I have seen this. All good as your post and others quickly took care of the issue.
I guess I can’t say how the tick box became unticked since it doesn’t happen automatically. I suppose the box may have been unticked accidentally. Same for locking the viewport. Maybe you wantted to use Zoom Selection and inadvertantly hit Lock.
Generally I don’t lock viewports. If I want to prevent them from getting moved I just lock their layer. That way they will still update if the SketchUp model gets updated.
