1. Export your updated model from your modelling/texturing software to a importable file (DAE works best) and use the same filename as the older version.
2. Start Lumion, load your scene and to pick the model that has to be updated.
3. Then click on reload-button in material-section, and the model will be updated from the in step 1 created file. Mission accomplished!

3.1 If you hold CTRL by clicking on reload, the textures will be loaded in high solution (as you used in your model).

I've had a few times where I had to go back into Sketchup to make some material/texture changes.

Then I reload in Lumion and about 90% of the model textures reload correctly.  There are always 2 or 3 textures that get messed up and they are completely wrong.

Example:  In sketchup I changed the texture of a pool wall and also erased a water texture.... Afterwards, I reloaded the updated collada file into lumion....the new pool wall texture showed up fine, but the texture for my fence turned into water and the texture for a house wall reverted back into its original texture and lost the changes I had made to that material in lumion. ???

I think when you re-export from your modeling program, some textures get re-numbered and Lumion seems to get confused and re-loads some things incorrectly.

How can one avoid this mix-up when re-loading?  Its a real time waster.

Did you change the texture or surface in Sketchup in groups or componants? Or regrouped/explode?

In sketchup I opened up my pool component and changed the color of some pool walls, and removed a flat plane that used to be a water texture. 

Then I reloaded the model in Lumion, and my fence (which I didn't touch in sketchup) changed into Lumion's water texture?  Then one of my other house wall textures reverted back to an original state and I had to re-do the Lumion material adjustment for that. 

I thought this was just a one time fluke, but its happened 3 times already (with different scenarios/changes in sketchup).

It's got to have something to do with removing geometry in sketchup....it seems that when you re-export, the new collada file re-numbers every texture and if it skips the one you removed, then this confuses lumion ???
