Does it tonemap? is there a way to change this, or a filter to use? First of all, have you set your AE project to a linear color space? If not, you'll get different results in AE than in Nuke, which always uses a linear color space. Once you do that, you should be able to get the exact same results with compositing your passes in AE that you would in Nuke/Toxic because the math is the same. To answer your question, if there is no working space set, then AE will directly convert your 32-bit 0.0-1.0 to 0-255 when it displays for the screen or outputs H.264. If you use a linear working space, then AE will preview the image with the sRGB curve and use that same curve when converting to an 16- or 8-bit format. (That's the simple answer, anyway.) The way to manage this stuff in AE is to set a project working space and then check the color space being used in the output module. AE tries to always show you what you'll end up looking at, doing all the necessary color space conversions behind the scenes. Brendan |
