Hi ilwedritschel, thanks for your feedback (Luckily I worked/lived in Germany for a few years, so my rusty German came in handy 
).
Fortunately, you already have 4 plug-ins for Lumion Basic 2, so it should be straightforward to sort out your license question and upgrade to 2.5 (just follow Arthur's instructions above).
Snow and rain are simple 2D effects and they don't "know" if an area is inside or outside a building. I don't expect this to change any time soon (as it's hard if not impossible to fix this), so you'll have to edit your videos to hide this fact. The only potential workaround I can think of is to make it possible to adjust the distance from the camera where the rain starts, so that you at least can make it appear to rain outdoors only. You're welcome to suggest this in the Wish List section.
You're right, it is currently not possible to turn Movie effects on/off (although it has obviously already been suggested a number of times). In 2.5 you can copy/paste effects on a per-clip basis, so what you could do is to make a copy of your effects, and then delete the ones you don't want. When you're done testing, paste the effects back into the clip. I know that this isn't exactly what you want, but it might make things a little easier.
The Underwater movie effect in 2.5 is a quick fix that Ferry implemented in order to make it possible to show an underwater view below user-imported models that use the Water material.
The developers are keenly aware of the fact that it isn't possible to create proper axonometric views + elevations and cross sections in Lumion.
Ferry actually carried out tests in April but was discouraged by the initial results.
Anything that relies on "projection" will not function correctly if you try to use an orthogonal camera, so the shadows and the ocean were no longer visible. There were other problems too, for example fog not working anymore, but I don't remember all of the details.
Let me know if you have any other questions, and feel free to contact us via email as well.
thanks for your comment.
i try to explane something what i think is going wrong.
1 1/2 jahr ago i was surching for a 3d-palme for sketchup, i found lumion 3d, wow i bought the basic with the tree library but not only the tree library the program is working well with my big scenes (sketchupmodels with 800MB and more ). that was my first test with the lumion free software.. i love lumion and thought the team is great the forum with your spontan comments and allway presents is super.
lumion is growing, and first time it goes to the right way.
i thought it will be a big tool for 3d-rendering and i can buy what i need (plugins), but now you offer lumion as a warehouse with 1600 parts etc. i do not need 1600 parts with balls and books and somthing like that.
you can never offer all parts i need from v+B or stark, shower and bath etc. there are 5000 to 10000 , or all street lamps etc.
what i need are tools to but parts (you can get everything from dealer in 3d) to the lumion library with some kind of changings (color, matirial etc.)
the same with trees and cars. i dont need 1000 gostcars with out driver, i need one or two where can i open the doors an puts there lights on etc. or i will made my one car from doschdesign or something like that to but this in the lumion library with animation.
the same with peoples etc.
the same with the material without name for wood only with numbers? witch kind of material? thats all not finish!
its not the best puplik to sell your program with the offer yo get 1600 part it cost only 1 or 2€ a part.
lumion 3d must be the best 3d-animation
tool in the world without a big 3d-warehause.
we need tools and a place in the forum where user can share lumion 3d parts and matirials etc.
sorry for my english and iam in hurry i have to work.
and thanks for the underwater tool, i feel like a red snaper.
ps. 3d-animation are only 5% of my works i have to manage 20 indian with a translator in hindy.
