DEV-thread - Blendigo v0.7 - material-editor-exporter

[joegiampaoli]

in indigo directory there's a file called inifile.txt, open it and edit the section "save_igi" to true, like this:

"save_igi" "true"

[paulo_gomes]

thank you joegiampaoli, it works!

but if i trie to run indigo within blender it doesn't

[paulo_gomes]

sorry!!! it worked! my computer it's a BIT slow. thank you

[joegiampaoli]

ok, I was going to tell you to let it run a bit longer...

Good it works

SMALL UPDATE

- removed surface compensation for lights - gain-value is equal to XML gain - use "efficacy" feature instead



And here some explanations for the previous implemented "EXTERNAL" material type :

If you like to use a special indigo-material that isn't implemented in the exporter-GUI, you can do this by including an external XML-file.
So write a XML scenedata file with your material inside with the correct material name as following:

Code: Select all

<?xml version="1.0" encoding="utf-8"?>
<scenedata>
	<material> 
		<name>my_material</name>
		...........
		...........
	</material>
</scenedata>

Then in blender create a material with the same name, open the Blendigo-GUI, select the material, set material-type to "External" and choose your external XML as filename.
When you then press the Render button, the exporter automaticly includes your external material-file and renders all possible indigo-materials

I think, I've seen this already anywhere, but I'll write it anyway:
Can you either make your Exporter Name-adaptive to .sphere , .rect and .plane , or add a button for primitives?
(If Deus is fast enough, maybe 0.7 also has vegetation and landscape primitives )

hi kram1032,
ok, will have a look on this... not so hard... should be in tomorrow (i hope )

I have been using your exporter for one day. Your exporter is brilliant. I am currently rendering two blender monkeys with a skull, a blood layer and a skin layer. And, let me tell you, it's looking good. And it's all thanks to your exporter

Hi

I tried to do BLEND material that contains NULL and Material with Alpha.
But after the export I get wrong code:

Code: Select all

<material>
		<name>null</name>
		<null_material/>
	</material>

<material>
		<name>okun_tex</name>
		<diffuse>
			<colour>0.8 0.8 0.8</colour>
			<albedo_texture>
				<path>okun.jpg</path>
				<uv_set>uv</uv_set>
				<exponent>2.300000</exponent>
				<a>0</a>
				<b>1</b>
				<c>0</c>
			</albedo_texture>
		</diffuse>
	</material>

<material>
		<name>blend</name>
		<blend>
			<a_name>okun_tex</a_name>
			<b_name>blend</b_name>
			<blend_factor>0.5</blend_factor>
			<blend_map>
				<path>okun_0.jpg</path>
				<uv_set>uv</uv_set>
				<exponent>1.000000</exponent>
				<a>0</a>
				<b>1</b>
				<c>1</c>
			</blend_map>
		</blend>
	</material>

As you can see two components are wrong and I have to edit them manualy. They are:
<a_name>okun_tex</a_name>
<b_name>blend</b_name>
I prepare the scene in this manner:
Two materials are applied to Mesh
The first one (lets call it "okun_tex") is DIFFUSE with Texture
The second (lets call it "blend") is BLEND with Mat.A:okun_tex and Mat.B:blend and Texture


Maybe this is not right method of preparing the BLEND material?

hi cooler_inc
if you like to get this:

Code: Select all

<a_name>okun_tex</a_name> 
<b_name>null</b_name>

you should set "mat-B" value to "null" in the GUI.
Assign the "blend" material to your object (and force blender to save "okun_tex" material... not that it get lost)
Btw: if b=1 and c=1 your blend will completely fall to one side... because a*x^2+b*x+c will be >1 in any case (perhaps let c=0)

[cooler_inc]

I just changed Mat.B: to NULL and script crashed.
Console message:

Code: Select all

NameError: Material "null" not found

Materials "blend" and "okun_tex" are already assigned to object.
Sorry for lame question but how to force blender for saving "okun_tex" material and what for?

[zuegs]

hi cooler_inc,
oups... ok i see the crash... will fix this this evening, sorry about. But this will be the way how to use the BLEND.

You need just to assign the "belnd" material to your object, but you could assign the "okun_tex" as second material or you can toggle the small "F" button on the blender-material-panel to force that material get saved too (because otherwise blender only save the materials that are directly assigned to a object)

[cooler_inc]

Thnx zuegs

Dunno if it's a bug or if I'm being stupid, or even if this has been said here already, but your largest lens aperture (F-Stop 1) seems to translate into a pinhole in the XML file. Of course, you can correct it there and put an aperture of 1 or just lower for a very shallow DOF but you might want to have a look at this.

Thx!
