Textured emission (HDR emitter)
A texture can be used to define the color pattern on an emitter.

This option allows you to texture an emitter with an image. You can use any of the allowed texture formats but we suggest using a high dynamic range format as MXI, HDR or EXR formats. The Intensity parameters works as a multiplier of the texture intensity, allowing you to adjust the power of your emission.
You can also use low dynamic range image (LDR), such as a jpeg, but the LDR image will get overexposed or underexposed sooner than a higher dynamic range image and will have less contrast.
You can also use Maxwell.exe to adjust the intensity of the MXI, HDR or EXR map using the Intensity slider in the MXI section (found in the Edit panel). Simply open your low-dynamic bitmap in the core rendering engine and save it to the MXI format. Maxwell Render will automatically convert your image to a high-dynamic range image. You can use the f-Stop and Intensity sliders to adjust your emitting image intensity.
