Post Render Script - python bhclassic to vrmesh

[LaidlawFX]

Trying to make a post-render script on a bgeo rop that when I write a .bhclassic it will rename it to .bgeo, and then I can have vray convert the h11 .bgeo into a vrmesh.

The post rename should be easy, but yeah... I stink at python, or the doing python in the post-render script has some weird syntax. I have switched the drop down to python. I am on windows, so not sure if that is throwing me off.

import glob
import os

for filename in glob.iglob(os.path.join(hou.expandString('`chs("../HscriptDirectoryPath")`'), '*.bhclassic')):
os.rename(filename, filename[:-9] + '.bgeo')[/CODE]

I would like to figure the vrmesh conversion on my own, but if some one know that easily, I would be happy to push off my python learning for the short term once more.

Thanks for the help.

....

One sec may not be a complete python noob, with the first part, of course it worked in the simple test scene I was about to post... guessing it a stupid slash thing

to fix slashes use

import os

filesPath = os.path.join(hou.expandString('`chs("../HscriptDirectoryPath")`'), '*.bhclassic')
fixedPath = os.path.normpath(filesPath)[/CODE]

You mean this vrmesh? I do hope you don't need it for today?

EDIT:

Beside, instead of this

filename[:-9] + '.bgeo'

use

"{0}.{1}".format(filename.split('.')[0], "bgeo")

to change extension in filename

So this is what I got with some help here... it seems to work... need to clear out the old files now and hope it works at render time

import glob
import os
import subprocess
converterPath = r"C:\Path\To\ply2vrmesh.exe"
for filename in glob.iglob(os.path.join(hou.expandString('`chs("dir")`'), '*.bhclassic')):
    filename = os.path.normpath(filename)
    #print filename
    newfilename = filename[:-10] + '.bgeo'
    #print newfilename
    os.rename(filename, newfilename)
    p = subprocess.Popen([converterPath, "-smoothNormals", "-flipYPosZ", newfilename])
    p.wait()
[/CODE]

Works?

Remember that if you want to run a file from Post-Render Script field on Mantra, you need to use

execfile(yourScriptPath)

This field expects code not a path so putting just a path to file will return error. Remember to expandString if the path is from variable

[LaidlawFX]

Ah ok, that explains why we ran into the error with the converterPath being inside

It creates the vrmeshes, but apparently you can not have multiple wait() commands to then remove the temporary .bgeo file. which would be the next step. :\

	    p = subprocess.Popen([converterPath, "-smoothNormals", "-flipYPosZ", newfilename])
	    p.wait()
	    w = os.remove(filename)
	    w.wait()
[/CODE]

I'm soo glad there are people smarter than me.... lol.... copy and paste the for loop to just do the remove, lol, soo simple

import glob
import os
import subprocess
converterPath = r[color=#008800][size=2][background=rgb(248, 248, 248)]"C:\Path\To\ply2vrmesh.exe"[/background][/size][/color]

for filename in glob.iglob(os.path.join(hou.expandString('`chs("dir")`'), '*.bhclassic')):
filename = os.path.normpath(filename)
# print filename
newfilename = filename[:-10] + '.bgeo'
# print newfilename
os.rename(filename, newfilename)
p = subprocess.Popen([converterPath, "-smoothNormals", "-flipYPosZ", newfilename])
p.wait()

for filename in glob.iglob(os.path.join(hou.expandString('`chs("dir")`'), '*.bgeo')):
os.remove(filename)[/CODE]

Thanks again mantragora
