im having display problems after i opened up houdini 12 i cant see construction grid and if i create an object i cant see it why is this happening? thanks

Try downloading H14, quite a few issues were resolved since H12. If that's not an option, what is your OS, graphics card, and graphics driver version?

Thank you soo much for replying i am really exicted to dive into houdini as a beginner but i have a very old computer 32 bit g450 lenovo with intel core duo since houdini is really a big program will it work on my machince swiftly mabey an older version? pls help thanks

For H12-13, you can try setting the “HOUDINI_OGL_SOFTWARE = 1” environment variable in the Control Panel, System> Advanced > Environment Variables dialog. This will use Microsoft's GL1.1 software renderer, which isn't terribly capable but might work well enough in a pinch.

The GMA 4500M in that laptop isn't capable enough to handle Houdini in hardware-accelerated mode, so the software renderer is your only option.

H14 and future versions require GL3.3, so the software renderer trick won't work for those.

i cant find houdini ogl
