ok here is the problem i have 3ds max 2011 and indigo 2.6.1 beta (i think) now i just cant seem to figure out how to work with IES light i created a target. photometric light selected web distribution,selected IES profile and nothing...then i thought id try with emitter material but i just cant seem to find where to select ies in the material editor or what kind of map to add well dont blame the newbie cant someone point to me what to do with screen shots if posible i have looked at this http://www.indigorenderer.com/forum/vie ... =19&t=7430 but where are emitter atributes anyway if anyone can halp me out would be cool

I could be wrong, but I'm not sure the max plugin has IES functionality yet.

Hi dtoxic,

Maxigo has IES support (just tested and works fine here). Steps you describe seem to be correct too.
Did you have your camera and/or tonemapping set up correctly? Maybe your light was too weak or smth?
Try with a single photometric light and reinhard tonemapping.

Ha, I was looking in the wrong spot for them too, I kept looking in the emitter material options.


Here's I got them to work -

Create > lights > photometric lights > target or free
Modify panel > general > Light distribution (type) > Drop down to Photmetric Web, then choose an IES file.


Here are two IES files that I know work w/indigo, use these to test =)

I am sorry but "where" exactly?
I follow this:
http://www.indigorenderer.com/documenta ... ies-lights
and that:
http://www.indigorenderer.com/forum/vie ... =19&t=7430
and again that:
http://www.indigorenderer.com/forum/vie ... 0&start=15
and finally that:
http://www.indigorenderer.com/forum/vie ... =9&t=11889



If i create a photometric light in 3ds max and add an IES files i have a Null result. (not exactly i have 1 pixel white where i have the center of my light )
even if i tweak my exposure control.
even if i choose an other ies file from http://www.indigorenderer.com/dist/ies-profiles.zip

If i create a plan with a indigo material i don't find where i need to put the link to the IES file.

So i probably misunderstanding something.

If i use a geometry to distribute the light, like a tube for example.
can i link an igm with an IES definition?

If it's correct (it seems no but..) can you send me the link to the technical documentation, i don't know how to do that in this kind of igm:

Code: Select all

<scenedata>
<material>
	<name>lamp</name>
	<diffuse>

	 <albedo>
	  <constant>
		<rgb>
		<rgb>0.5 0.5 0.5</rgb>
		<gamma>2.2</gamma>
		</rgb>
	  </constant>
	 </albedo>

	<base_emission>
		<constant>
		<rgb>
			<rgb>150000.0 150000.0 150000.0</rgb>
			<gamma>1</gamma>
		</rgb>
		</constant>
	</base_emission>

		<layer>0</layer>

	</diffuse>
</material>
	
<layer_name>
		<layer_name>Layer-0</layer_name>
		<layer_index>0</layer_index>
	</layer_name>
</scenedata>

Thank a lot by advance for your help
