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: ... ies-lights
and that: ... =19&t=7430
and again that: ... 0&start=15
and finally that: ... =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 :D )
even if i tweak my exposure control.
even if i choose an other ies file from

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


		<rgb>0.5 0.5 0.5</rgb>

			<rgb>150000.0 150000.0 150000.0</rgb>



Thank a lot by advance for your help :)
