Raw+ output is just two separate files stored in memory card: one raw file and one jpeg file. You will have a jpeg file, but it won't make Photoshop render your raw file like Pentax custom image.

No. The custom image styles of Pentax are proprietary, the details of the rendering model is not included in raw files.
Originally posted by Zucca The problem is I modify the color profile in my camera so I don't use it in default but in Photoshop you see only the defaults
I had the same problem. To solve this problem, I shot a color chart with calibrated exposure (using spot meter on 18% grey), then I converted the chart image to jpeg using the camera. Comparing out of camera jpegs of each custom image, to the raw file converted with rawtherapee, I adjusted while balance, black level, white level, tone curve and HSV (Hue, Saturation, Value) for each hue of the color chart to match camera custom image with rawtherapee.
