Blendigo 3.6.5.1

Hi guys,

Any word on the Dupligroup export error? Linked objects work fine, it's just Group instances that are giving up.

I think the problem come when section plane feature was implemented, consideration was not taken for empty having no data.

I made a hack, it seems to work if you're desperate, probably it breaks something .

in export/geomtry.py, find:

Code: Select all

		if(obj.data.indigo_mesh.section_plane):
			xml = SectionPlane(obj.matrix_world.col[3], obj.matrix_world.col[2], obj.data.indigo_mesh.cull_geometry).build_xml_element()
			
			model_definition = (xml,)
			
			self.ExportedObjects.add(self.object_id, model_definition)
			self.object_id += 1
			return
			
		# Special handling for sphere primitives
		if(obj.data.indigo_mesh.sphere_primitive):
			xml = SpherePrimitive(obj.matrix_world, obj).build_xml_element()
			
			model_definition = (xml,)
			
			self.ExportedObjects.add(self.object_id, model_definition)
			self.object_id += 1
			return

Add this before if obj.data != None:
thus;

Code: Select all

		if obj.data != None:
			if(obj.data.indigo_mesh.section_plane):
				xml = SectionPlane(obj.matrix_world.col[3], obj.matrix_world.col[2], obj.data.indigo_mesh.cull_geometry).build_xml_element()
				
				model_definition = (xml,)
				
				self.ExportedObjects.add(self.object_id, model_definition)
				self.object_id += 1
				return
				
			# Special handling for sphere primitives
			if(obj.data.indigo_mesh.sphere_primitive):
				xml = SpherePrimitive(obj.matrix_world, obj).build_xml_element()
				
				model_definition = (xml,)
				
				self.ExportedObjects.add(self.object_id, model_definition)
				self.object_id += 1
				return

Hey William,

Nice find. Does it work OK with everything else? Can't afford to break anything at the moment, so if it's not safe yet I'll keep nagging Glare

[William]

I have no idea, use at own risk
Didn't even make a scene/objects for indigo yet, this bug always in the way of using any assets or using any old scenes from other renderers, just couldn't be bothered making all objects local and duplicates real because this results a mess.

Some things that could be improved in Blendigo:

- Dupligroups / group instances (NoneType object has no attribute 'indigo_mesh')

- External materials don't seem to work when there is a Blend or Double-Sided Thin material with sub-materials ('no such material as <x>'). I suspect the problem only occurs when there is a sub-sub-material. Seems Indigo saves the first sub-materials in a Blend or Double Sided Thin material, but then doesn't look to see if those sub-materials have any children. Heartless. This may be an Indigo issue with saving materials.

The interface for making materials before was much better, where you could see each material in a stack and could better visualize the material structure.

- Transmittance color needs to be exposed in materials settings (for Double-Sided Thin)

- Depth and Shadow passes need to be exposed in render settings.

- PyNodes are on their way into Blender! Should make Indigo material editing a fair bit easier

PyNodes are merged into Blender trunk:

Should make Indigo material setup easier?

This stuff would be great!.... so would a bugfix

[Polinalkrimizei]

Should make users of other exporters pretty jealous

Nice find, have committed the fix.

Luxrender already got basic pynodes support!

Awesome! Exactly what would be amazing with Indigo, along with an ISL node.

Perhaps things like Blender clouds and marble textures could be loosely converted to ISL functions?

From my experience with Maya it's not very difficult to set custom nodes up. The most complex part is the one involving the realtime viewport feedback. I for one skipped that part in MtI.

The rest is about defining inputs and outputs types, names and default values mostly. Then comes the exporting stage wich calls outputs and read them before an eventual data processing.

Sorry if I'm trolling, I'm a fool by night as well
