convert the texture to a mxi and use it as emitter?

In that case I'm not able to texture my model in Sketchup, like Photomatching?

Within the SketchUp plugin use the Maxwell embedded character material type of "HDR Image" and choose an MXI/EXR/HDR to light with... it will respect whatever UV mapping you already have assigned to your SketchUp model.

Best,
Jason.

When using the HDR Image, it will show the HDR and not the texture I applyed. So I'm a bit lost.

Let's say I have a shopwindow image and like to have it self iluminated. The image itself is Photomatched onto a face.
Convert this texture seperatly to a MXI or HDR does not allow me to reimport this image in Sketchup again.

I imagine it should be possible to use the image editor out from Sketchup, to convert this Image into a HDR. What Program is recommended for JPG to HDR/EXR?

So what is the exact way to do this?

Use/create 2 versions of the same image, a JPG for photomatching and a converted MXI for the emitter material.

Maxwell will automatically replace the JPG with the MXI at render time (as far as illumination) but the UV mapping created via photomatching will be respected.

Best,
Jason.
