@Keet

I tried your suggestion, but there are still the same problems.

@Puybaret

I tried SunFlow, and there are also the same problems.


I openned the original DAE/Collada file with Blender, and it showed some mechanical objects only viewable with blender. There was also some misplaced points for the greenhouse object.

I think I have finished my own model of greenhouse, it is a very basic model, and seems to render correctly.

I made it modulable, one duplicable element for the middle, and one element for the begining and the end of the greenhouse.

So with these two elements, I can make a greenhouse of the lenght I want.

However the model isn't as well worked than the one I have downloaded, there are no doors in the plastic cover, at the beginning and the end on the greenhouse.
