Hi yyl3130

What version of Lumion are you running?

Your basic PC specs look OK.

The first error is a message generated from SpeedTree, the software which renders trees and plants in Lumion, and is an 'obscure' out of our control message.

So this only happens if you set the Low Mem switch when the scene with your imported model is open?
Does it happen for any other scenes such as the two Sample scenes - Wegner and Artistic Effects.

How complicated was your model, what is the number of 3D Points in your scene?:
a) when F1 key pressed (lowest editor quality?
b) when F4 key pressed (normal, highest editor quality)?


If it's not happening with the Low Memory switch off, then don't run in low memory mode, or is the model so complicated you get low FPS.  Why is it that you need to run Low Memory?
