Optimizing VEX texture function Aug. 2, 2018, 10:44 p.m.

I was wondering if there is a way to optimize the VEX texture() function when reading many files. My workflow reads the alpha of a image file, then writes an attribute on the (many) points of the geometry. This in a wrangle loop.

Would reading from the image in COPS be faster or slower?

I tried to reduce the files in size (from 17 Mb to 60 Kb) but made not big difference. Files are 5K resolution, so maybe there is no much room for optimizing here?


File SOP not loading .ply [SOLVED] July 5, 2018, 7:34 p.m.

So apparently a blank file named “Program” at C:\ was causing the issue. I am not sure what software put that there, but Windows was complaining about it every time I restart. I deleted it. Now Houdini can load .ply again. The weird world of computers…

File SOP not loading .ply [SOLVED] July 3, 2018, 7:20 p.m.

Recently the File SOP doesn't load .ply anymore. I've tried in another machine with same Houdini version (16.5.473) and it works fine. Tried the usual, restart, uninstall and reinstall Houdini. Windows 10.

I tried to open with gplay and it doesn't work either. But when I use gply.exe to convert the .ply to .bgeo from command line, it works fine and converts.

I could load .ply with no problems until a few days ago. I did install some software, Microsoft Visual Studio and some packages with it. Could that be the issue?
