    thank you very much jason! wooohooo finally the possibility to put IES in my scenes!

    and i was this close to buying the full render suite just for IES lights 😉

      I'v been reading all the previous, but I'm still having problems with my lights. I'm using Sketchup pro 8 an the Maxwell plugin only. I added a test-render (attachment: test 7), in which I used no artificial light. Obviously, it needs some artificial light, but I've been trying emitters (on a rectangle) and an IES (on as spere) but it keeps on turning black. I've tried reversing the material, but nothing worked so far.

      Stupid thing though: in a test-setup I made (attachment: test 2), the lighst do work (although I'm still struggling with the settings)

      Please help!!!


      Not fully rendered, because it was just a test.


      Same here

        intensity too low? Maybe try with multilight.

        Did you try bouth face orientations? Some time ago a had the problem that emitter faces got reversed on export.

          Hi, I am a newbie to Maxwell - I have the free Maxwell render plug-in for SU.

          I have read all the above posts and I appear to have the same problem as many.

          I am working in an outdoor scene.

          I read the whole of the manual that is relevant to the above and followed the guidelines, but I'm not getting any light emission from geometrical objects created. I applied light emitters to each face of planar emitters and then made them a group but still no light. I tried various means: such as IES lights, customised emitters, daylight and 1000W lighting.

          I have HDRI loaded as background and also in associated channels, reflectance, etc. Can this affect the light emitters? But I did disable the HDR at one point.

          Many thanks in anticipation for help with this.

            Sketchfield, check units and scale of the objects in your 3d model, make sure that you are working with real scale and the size of objects correspond with units used...

              Thanks for the prompt response novena - the objects scales certainly need to be reviewed and revised. I will give it a go ... here's hoping!

                Interesting one - under materials texture I clicked 'Link to Application' instead of 'Texture' and hey presto! we have light. Link to application seems to give a more exact fit with the selected material, emitter, etc, but correct me if I'm wrong.

                I also had to review a range of things like the exposure values, scale of objects and so on. Trial and error the order of the day! Thanks again.

                  good to hear that it's solved!!! 😄
                  interesting the issue with 'link to application' and 'texture' will give it a try myself

                    Just wondering is anyone knows how to hide Emitters from the camera so you get the light but not the geometry that it is coming from.

                      Hey, right click the component, you'll see a sub menu, go to Maxwell, another sub menu will appear, select 'from camera', there's a few other options in there too for invisibility, for example, if you want to illuminate an area and there are windows/mirrors and you don't want the actual source of light to be visible in the reflections, then you'd need to enable 'from reflections/refractions' too.
