slowdown in lumion

Hello,

I have a project that has many plants sketchup (250 to 300 plants). the project has slowed in lumion. (video of 14 seconds in 4 hours and if there are no plants sketchup I spend 20 minutes)

is there a method to reduce the slowdown that the game other layers in lumion?

Thank you in advance.  ;)

At a guess I reckon these particular Sketchup plants are probably not very low-poly?
A screenshot with your triangle count displayed (upper right corner) helps...

According to your screenshot your scene counts 500 million triangles.
With shadows on that makes 1 billion triangles.
You know this is A LOT?

How much triangles do you have without the sketchup plants?

not cool if you can not use sketchup plants.

the solution is that it takes lumion enlarges his library (if I understood correctly)

Lumion uses Speedtree for its plants.
Speedtree plants=highly optimized.
You can use Sketchup plants but you should not use lots of HIGH POLY sketchup plants ;-)
If you must use them, then Lumion will render slower.

Go here:
http://lumion3d.com/forum/new-features-wish-list/speedtree-guide-and-wish-list/
and make a request for the plants you need.
That's all the advice I can offer.
Sorry but there is no 'easy' fix.
