Andy Posted November 7, 2016 Share Posted November 7, 2016 Hi Pylon, I don't try recently but when I scaled model with maxwell plug-in to obtain depth of field maxwell don't scale light as softbox so the illuminate of render changed. In very old maxwell plug-in (before you made maxwell) lights are scaled consequently; now this feature is useless because every change of scale changed also illumination.

pylon Posted November 7, 2016 Share Posted November 7, 2016 Hi Andrea, This has not been changed. It is likely that you were using using a different luminance model in your older files. If you want the illumination to "scale" with the geometry, it is necessary to select a luminance model that considers the physical area of the light. Both Lumens (lum/m^2) and Luminance (cd/m^2) are defined in terms of area, so lights with this model will appear the same regardless of the Scale Model setting. On the other hand, the Power + Efficacy, Lumens, and Candella models define the total output of the object, so lights with this specification will appear brighter when the scene is scaled down. You can also change your camera exposure, if necessary. http://support.nextlimit.com/display/mxdocsv3/Area+emitters Link to comment Share on other sites More sharing options...
