Python flipbook generation outputs only one frame

[Krion]

Hi,

From the sidefx docs I stole this code:

desktop = hou.ui.curDesktop()
viewer = desktop.paneTabOfType(hou.paneTabType.SceneViewer)

# Copy the viewer's current flipbook settings
flipbook_options = viewer.flipbookSettings().stash()

# Change the settings however you need
# (for example, set the frame range and output filename)
parmi = hou.parm("/obj/comments/addtoflipexport")
flipbook_options.frameRange( (1, 5) )
flipbook_options.output("$HIP/flipjes/flipbook_FRM=`padzero(4, $F)`.jpg")

# Generate the flipbook using the modified settings
viewer.flipbook(viewer.curViewport(), flipbook_options)

I did change the normal $F from my original filename to `padzero(4, $F)`, but it still only outputs one frame.

How do I make it update along with the frame number while the scene is generating the flipbook?

Thanks in advance.

You can use this code if you want, it will create small UI with name of flipbook and you can manually set whatever frames do you need.
also it will create two folder: 1 jpg sequence, 2 hip file

Important! You have to have in your project folder "flip" (it will save your flipbooks inside this folder) and the name of hip should containe version, as example "test007_sc4546_v003_explosion")

so flipbook will take this name "explosion"

 

import toolutils
import hou
import os
import sys
import re


from datetime import datetime
### frame range ###
start = hou.expandString('$FSTART')
end = hou.expandString('$FEND')


### ui ###
text_to_search = hou.expandString('$HIPNAME')
pattern = re.compile(r'[v](\d{3})[_](\w*)')
matches = pattern.finditer(str(text_to_search))


for match in matches:
	def_name = str(match.group(2))
	print (match.group(2))


gamma = 0.7
#def_name = "flipbook"
list = ["Name", "Fstart", "Fend", "Gamma"]
list2 = [def_name, str(start), str(end), str(gamma)]
read = hou.ui.readMultiInput("Flipbook settings", list, initial_contents = list2)
range_start = (read[1][1])
range_end = (read[1][2])
gamma_in = (read[1][3])


### folders ###

date = datetime.now().strftime('%d.%m.%Y')
job_folder = hou.expandString('$JOB')
hip_name = hou.expandString('$HIPNAME')
flipbook_folder = job_folder+"/flip"
data_folder = flipbook_folder+"/"+date
version_folder = data_folder + "/v0"

if not os.path.isdir(data_folder):
	os.mkdir(data_folder)


filelist = []
os.path.isdir(flipbook_folder)

find = version_folder.rfind('/')
cut_path2 = version_folder[:find]
#print cut_path2


for folder in os.listdir(cut_path2):
	pattern = re.compile("^v(\d*)$")
	result = pattern.match(folder)

	if result is not None:
		num = int(result.group(1))
		filelist.append(num)

                

mx=0

if len(filelist)!=0:
	mx = max(filelist)
	version = mx+1
	version_folder = data_folder + "/v" + str(version)


jpg_folder = version_folder+"/jpg"
hip_folder = version_folder+"/hip"

file_name  = str(jpg_folder)+"/"+(read[1][0])+".$F4.jpg"
os.mkdir(version_folder)
os.mkdir(jpg_folder)
os.mkdir(hip_folder)
hip_name_save = hip_folder+"/"+hip_name+".hip"
hou.hipFile.save(hip_name_save)


##### Copy the viewer's current flipbook settings
cur_desktop = hou.ui.curDesktop()
scene = cur_desktop.paneTabOfType(hou.paneTabType.SceneViewer)
flipbook_options = scene.flipbookSettings().stash()
flipbook_options.frameRange((int(range_start),int(range_end)))
flipbook_options.output(file_name)
flipbook_options.gamma(float(gamma_in))
scene.flipbook(scene.curViewport(), flipbook_options)

#newPath = file_name.replace('/', os.sep)
#hou.ui.displayMessage(jpg_folder) 
#os.startfile(jpg_folder)

Thanks for sharing alex333d,

I will look at the code and try it out.

$F4 gets evaluated inside the python script so it's "baked" into the code,
there's probably a cleaner way, but this works:

flipbookpath = "/tmp/flipbook/mysim"
flipbook_options.output(flipbookpath+".$"+"F4.jpg")

Have to admit that if im getting into VEX now, scripting and python has never been my area of expertise.

It would be great to have a python script, which to from a selected folder, open each hip file, and save a flipbook thumbnail preview image of the last output selected.

Or actually more interesting will be to have it operate every time you save the file, with the jpg preview image with the same name as the hip file...

The script under the Houdini blue print web site is brillant
