HI,
I'm new to Houdini and There is a really strange problem with l-systems that even re-installing windows and Houdini didn't fix it. when I make a simple l-system I cant change the type of it to default presets like branch or crack. after clicking on presets nothing happens. Tried this on 2 other laptops and everything was just fine.
Plz help me, Thanks

can you make a file with your default l-system ad attach it.
I have no trouble using the presets.

what graphics card are you using?

I have a gtx 980m, the problem is from my laptop not Houdini because its ok on my other pc and I cant find it.
thank you for your reply
