I think I now know what the problem is.
You are exporting the mesh with python and usings strings to stream the information into the RAM ...

maybe big meshes are too big for the datatyp string in python. Maybe you should overthink your exporting procedure and either split strings or use a better datatyp/algorithm.

Code: Select all

exporting mesh "sandbank"

ok in general talk to ono in chat it was mentioned smartden may like an idea for making render region for the official blendigo.
I offer an idea I used making use of blenders border tool - unfortunately I could not see a way to use the shift b rectangle to draw a region for the script to read directly but conversely you can set up the script so that it will draw the border via slider changes to the cameras window realtime for visualising the output - which is all you need really
see pic attach
its not very clear here but I have sliders for left , right , top , bottom position
possibly that works for him too

i got the region render with shift-b and fixed the memory bug with big scenes. but i have still to fix some minor bugs and then i publish the new version. be patient a little bit longer...

yea, but i need a big scene(that crashes now) for test. or sombody who wants to play with my buggy blendigo

Try that one, it will crash for sure. It is a displaced wooden plank with 2 subsurf modifiers applied, increase the "render levels" of the 2nd one if that's not enought.

Hi all, nice to see the success of blendigo! Thx a lot to SmartDen!
Here a code i used to get the right materials from OB and ME at same time (if compress=False then list indexes matches indexes used inside mesh.faces):

Code: Select all

#-------------------------------------------------
# getMaterials(obj)
# helper function to get the material list of an object in respect of obj.colbits
#-------------------------------------------------
def getMaterials(obj, compress=False):
	mats = [None]*16
	colbits = obj.colbits
	objMats = obj.getMaterials(1)
	data = obj.getData()
	try:
		dataMats = data.materials
	except:
		try:
			dataMats = data.getMaterials(1)
		except:
			dataMats = []
			colbits = 0xffff
	m = max(len(objMats), len(dataMats))
	if m>0:
		objMats.extend([None]*16)
		dataMats.extend([None]*16)
		for i in range(m):
			if (colbits & (1<<i) > 0):
				mats[i] = objMats[i]
			else:
				mats[i] = dataMats[i]
		if compress:
			mats = [m for m in mats if m]
	else:
		print "Warning: object %s has no material assigned"%(obj.getName())
		mats = []
	return mats

Off topic: Zuegs! Long time no see. How are you? Send me a PM if you want.

Sorry for my OT.

I'm a little confused on how to install Blendigo. Do I run the installation steps then the Blednigo Installer? Or just pick one of these ways?

Thanks.

SmartDen wrote:Requirements:
- Blender 2.45
- Python 2.5
- Indigo v1.0.1

Installation:
- Place Blendigo in ./blender/scripts
- Dont forget to edit Indigowrapper.conf to specify your indigo location and put it in ./blender/scripts/bpydata
- put preview in the indigo directory

Download, install, run and post your experience

Have fun!

Note
- For Photometric lights(IES) use small planes(i suggest 3.5cm x 3.5cm)

Blendigo v104 installer
*added aperture diffraction
- supported types: circular and generated. image comes soon
*watermark default is off

Blendigo v101 installer

Posted: **Tue Feb 05, 2008 6:48 pm**

It depends of your OS, use blendigo v104 installer if you use XP, try manualy with other OS

Setting up a blended material in Blendigo 1.0.4 I forgot to select the "Material B" and so previewing the material or exporting the scene results in Blendigo crashing with this Python script error:

Code: Select all

Traceback (most recent call last):
  File "<string>", line 2803, in buttonEvt
  File "<string>", line 1231, in materialButtonEvt
  File "<string>", line 1945, in exportMatPreview
  File "<string>", line 673, in exportMaterial
  File "<string>", line 677, in exportMaterial
NameError: Material "" not found

I think it could be useful to insert a check warning the user and so avoiding Blendigo to quit.

Thank you!

BigFan,
How you get that blendigo interface? Is this some sort of your cooking? Could you share?

Posted: **Wed Feb 06, 2008 6:00 pm**

hi Woodie,
its a variant based on an older version of blendigo I keep reheating for use with Solidworks and for Indigo tasting evenings

its somewhat different now in appearance and slightly different in function from the blendigo available here
I would really rather you use the official blendigo that Smartden posts cos I dont want to maintain it for public use or have a number of versions in circulation causing confusion
I think he will post an update quite soon
