Since the Looks don't work in Resolve you have to add them manually using another node.Īdd an OCIO File Transform node and look for the necessary LUT in the Looks sub-folder of the color management folder in Blender (in this example the lut is Filmic_to_0-60_1-04.spi1d for Medium Low Contrast). Open fusion tab, load the EXR file and add a Ocio Color Space node, load the OCIO config file (config.ocio) from your blender folder and set the Source Space to Linear and output to Filmic Log Encoding. To match the images, as cleverly pointed out by both images would need to undergo the same color transforms. Note how they curve at the top, and some (in the green and blue channel) don't reach 100 percent, giving the flame a "yellowish" tone.īringing the files to resolve shows the same difference. On the right of the image is the PNG, the vectorscope shows how the highlights are scaled down to a displayable values (thanks to the color transforms called "filmic"). If sampled, some of the values in this EXR exceed a value of 24 on the red channel, way over what the display can deal with. All values higher than one or 100% are ignored. Notice how values over 1 are ignored and "hard clipped". The bottom of the scale is 0 (black) and the top 1 (or 100%, meaning white). On the vectorscope you can see how the image brightess values for each channel are represented. All values past 1 are displayed as "clipped" or "pure white".Ī graphic to illustrate. How to match an EXR (linear scene-referred information) to a PNG (in display referred values with sRGB "gamma" curves) of the same image in resolve?Įven though both images are generated from the same render layer in blender, they are going through different pipelines and the values don't match: The PNG is encoded with a gamma curve (sRGB, 2.2) and the information has been scaled to fit within the 0-1 values of display referred, while the EXR is still in Scene-Referred values that exceed what the display is capable of representing on the screen.
