I guess you're talking about applying LUTs in realtime. The .cube files are loopup-table format, but for realtime, we rather need the equivalent PNG : here is a tutorial to convert a .cube file to a PNG file suitable for Millumin.
Then, you can use this PNG file with a shader applying the LUT effect : for example, you can use this one, and replace the PNG files accordingly. To install such a shader for Millumin, please read this tutorial.
Could anyone help me to make this (or a similar) LUT Shader ready for use in Millumin2?
I don't know how to apply the PNG Files. In fact, I get a "shader warning" (see the pic attached). I have no idea, how to apply this image (lookup_toned.png). It's in the library, on the same layer, on the layer above … I used the shader as a source and effect to a the layer. Unfortunately, I'm not into shader coding. It's like looking directly at the matrix.
Any help is very much appreciated!
(It's for a theatre company I'm working on. This could lead to a new millumin customer ;–), since I could easily do it in Isadora, but Millumin2 would be a much easier solution).
You need to add your lut .png files alongside the "LUT.fs.fs" file.
Please find attached an zip containing a working example. You just need to put it inside the 'ISF-effects' folder as shown here (and restart Millumin).
If you want to change the luts by yours, just replace the png files and change their names in the shader code
