CONNECT still slow

I have some problems .

The file size is only about 800 MB -  i put some xfrog trees etc..  I have NVME disks and  Nvidia 1080 GTX

It's horrible to change tree, move tree or change materials. Even rotate and refresh the window need few seconds. Any suggestion ?


  • Hi Martin,

    You should have used shared cells for all the trees and plants these are what is taking so long to load and display. I would delete all of them compress the file and place shared cells using our Populate tool. The Xfrog trees from European 3 are all to heavy unless the whole point of the render is to see a tree. If you use the ones from European 1 or 2 they are much smaller. In any case using shared cells for these will make your file load and display faster and also they will be replicators in Luxology and render faster as well.

    I had David Stradley who works on our display engine have a look and here is what he found. I am not sure where the cells that are on the last two levels in list below came from but they are the slowest.

    Hope this helps,


  • Jerry , one more thing.

    When i use Populate - i can add any 3ds or OBJ trees  and this works the same ( smaller filer and faster ? )  or i need to

    prepare all files ( trees ) before , i mean i need to save it as dgn or cells before put in Populate ?

  • You will need to place as cell you can save your SKP, OBJ or 3DS as dgn then change the model name so it makes sense. You don't want everything you place saying default model. Make sure you are happy with materials and they are attached materials not assigned. You can import models into one DGN or CEL to create cell library.
