Hi, I'm having a trouble… the waveform deform is not working. I already “re-install” houdini, and still having the same trouble… I dont know what can be happening…

Houdini 9.5.241
Windows XP sp2
AMD 64 X2 4600+, 2GB RAM
mmm… Python 2.5.2 and 2.6 installed (for blender)
mmm… i dont know what else can i descript about my computer, I have an environment setting “PYTHONPATH c:\python25…” and nothing more…

The console says:

Any advice will be welcome, . Thanks

nobody knows? shame… i still have the trouble, i dont know what is going on

No issues here on the latest build and on linux. Only python 2.5 here. Could you deinstall python 2.6 easily and then see if you still have this error?

I still have it,
This week i will research about that, trying different things

The problem is actually not Python related at all. The info that is printed to the console is in regards to a problem with VEX, specifically in this case a problem with the wave shape VOP SOP that is in the Waveform asset. It looks as though Houdini is unable to compile the code generated by the VOPs because of an error in the Compiler command. Without seeing it it is hard to know exactly what the problem is.

If you dive inside the asset and examine any warnings, as well as the contents of the Compiler parameter it may lead to some understanding of the problem and we can be of further assistance.

Also, a word about Python and Houdini. On Windows, Houdini does not use the system install(s) of python: it uses a python distribution that exists in the install directory so your version 2.6 will not cause any problems with how Houdini operates.
