Gaussianspectrum works fine. You must choose a narrow width to get the color that you want. The default width of 400 is too wide. Try 50 or so and then slide the wavelength value to see the color change.

Regarding the floatimage versus the image data type, it is in the manual on page 23. Sometimes people will use a full color image as a diffuse and bump map / specular map when they don't have separate maps for each. Or, they could be using a full color image that only contains greyscale data.

The diffuse map needs all the color data so it should be loaded using the "image" data type. All the RGB data will be used by Octane Render. If the user then used that same image for a specular map or bump map (which only requires a greyscale image) then it would be a waste of video ram. If the user loads the full color image using the floatimage data type, the image is converted to a greyscale image which results in much lower video ram being used.

Here's an example.

I have a map of rusty steel that is 3.12 MB. When loaded into Octane using an "image" type, it takes up 43 MB. When that same image is loaded as a floatimage data type, then it takes up 11 MB.

Does that clarify the usage?

and the demo is coming.... when?

Im not 100% sure we need Radiance to answer but...
I think its coming with the beta 2, wich is coming very soon
That mean its gonna be a demo with the features of the beta 2

Because the only difference between current demo and current beta is save / load + bugfixes etc...
