Juraj's playground

Hello community,
I am creating this thread where I will be posting links to my tests, experiments, RnD's and other uncategorizable stuff.

Also often I will include scene files so feel free to explore them and to learn how not to do things

...hope it will help somebody, somehow.

Great work Juraj! Some really clever and time saving stuff in there! Would you mind sharing your 'Save Increment' tool

[stickman]

wow.... fantastic tools!
Any plans to release these? Would make a great PulseOfLife bundle!

also ... are the LOD switches easily hooked up to distance-from-camera?

Hello, thanks! Glad you like it  Unfortunately I cannot share scripts because of the university policy, but will try to write a new one save incremental function  

# splits versioning string into letter and number, e.g. v025 -> ['v','025']
def verSplit(ver):
	head = ver.rstrip('0123456789')
	tail = ver[len(head):]
	return head, tail

# save incremental, tries to preserve version formatting
def saveInc():
	hipname = hou.getenv('HIPNAME')
	if hipname != 'untitled':
		v, num = verSplit( hipname.split("_")[-1] )
		num = str( int(num) + 1 ).zfill( len(num) )
		newName = hipname.split("_")
		newName[-1] = v + num
		newNameStr = hou.getenv('HIP') + "/" + "_".join(newName) + "." + hou.getenv('HIPFILE').split(".")[-1]
		hou.hipFile.save(newNameStr)
	else:
		print "cannot increment version name in untitled.hip"

Hi, thanks  Maybe, but this setup is not very portable and was made for our pipeline. It would require a bit of work to prepare for release and to make it work in most of the environments.

LOD switching would not require much of work in this setup. Just computing distance to render camera and then thresholding it into an LOD attribute. But in our case manual decisions proved to be most suitable.

could the particle shaping force tool be shared here ?

Hi, unfortunately I cannot share the whole setup. I shared as much as I am allowed in the blog post explaining the process of implementing this technique.
Hopefully later I will be able to put it here, but not now.
