Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Maya->Indigo0.5.3/0.5.4 Exporter Script

Well, people, I haven't programmed in a while. Now I want to make an MEL script that takes a Maya scene and makes an Indigo XML file.

So far- this is what my program outputs:

Code:
<?xml version='1.0' standalone=no>
<!--Exported from Maya-->

<scene>

<renderer_settings>
	<width>640</width>
	<height>480</height>
	<metropolis>true</metropolis>
	<large_mutation_prob>0.2</large_mutation_prob>
	<max_change>0.025</max_change>
	<russian_roulette_live_prob>0.7</russian_roulette_live_prob>
	<max_depth>1000</max_depth>
	<bidirectional>true</bidirectional>
	<strata_width>10</strata_width>
	<frame_upload_period>20</frame_uplod_period>
	<halt_time>-1</halt_time>
	<logging>true</logging>
	<image_save_period>30</image_save_period>
	<save_tonemapped_exr>false</save_tonemapped_exr>
	<save_untonemapped_exr>false</save_untonemapped_exr>
</renderer_settings>

	<tonemapping>		<reinhard>
			<pre_scale>2.0</pre_scale>
			<post_scale>1.0</post_scale>
		</reinhard>

		<colour_correction>1.0 1.0 1.0</colour_correction>
	</tonemapping>

<camera>
	<pos>2.852831591 -31.3782011 32.76079742</pos>
	<up>0 0 1</up>
	<forewards>-2.852831591 31.3782011 -27.63515811</forewards>
	<aperture_radius>
Yes, the numbers aren't just random outputs, they are actual processed positions. The camera target is a locator (with default name). The user can add an aim constraint to the camera from the locator if they want, it won't affect the script anyway.

Soon, I will have the vectors normalized, but, until then, this will have to do.

Also I'll have a window that prompts you, asks for settings, basically, a UI.

fast update- didn't know Maya had a target camera, so now you have to create a camera (camera 1, dont rename) and, instead of a locator, my script uses the camera target as the locator.

EDIT- Maya has just solved a big problem of mine- the up vector. Maya has a camera called Camera, aim, and up! I can use this to my advantage! :attn:

but you'lll have to use that kind of camera or else it won't export (the script won't run)

Hmm, I think you'we got the basics right but as I don't know anything/very little of the Indigo file format I can't give you much C&C.
Yay for 13 year old programmers user added image

That was exported with my script!!!!

I won't post code because I really don't want to be plaigerized, since my exporter is the only one around for Maya! (apart from LaLiLuLeLo from the flipcode forums, and his doens't work with Indigo 0.5)

Mine doesn't either but it will in an hour or two.

Later,
Matt

ok ok!

I can export a full file now- plese try it out.. it doesn't work on my comp, no clue as to why the f**** it doesnt work. It tells me it can't read line -2.233.user added image

no meshlights or any kind of light for that matter, use it the same way you used LaLiLuLeLo's script, but:

Lambert materials are plain diffuse

Phong materials-

Color is actual color

Reflectivity is specular color

If you want a non-constant specular color (eg 1 0 1 instead of 1 1 1) you need to set reflectivity to 0 and use the reflected color gauge

Cosine power is specular sharpness (warning- it is multiplied by 10- eg. 12 is 120 and 0.3 is 3)

you need to use a camera- camera, aim, and up. Don't rename it.

yeah- same here.

Odd indeed... and I wonder why! I mean, my 3ds Max files are just fine. I'll try to export an identical 3ds Max file and see what's up.

an identical 3ds exported file runs just fine.

I talked to nick (writer of Indigo) and he said he'd tell me what it is, if it's not because it can't find the file, which i'm sure it can.

This is making me maaaaaaaaad. I really want to solve this problem!!!1
