Please Include Blend Modes as supported properties within Essential Graphics
I was surprised to find that there is no way to include blend modes in your essential graphics both when building in AE and building in PR. The only property is opacity which does not tick all the boxes blend modes can. I even tried workarounds to find channel effects with blend modes as options and could not find one. I think this would be a simple addition that would have a large positive impact.
Thanks for your request and agreed!! There is a way to cheat this a little bit in Mogrts using the Media Replacement workflow, but it would be limited to a selected blendmode.
Media Replacement allows you to create an Essential Property control from an image, video, .psd, or .ai layer in AE. Using this control in Premiere allows you to them drop new media into the control in the EGP and have that media render via the Mogrt, i.e. all blendmodes and effects in the Mogrt will be applied to that new media. Here's a few images of a Media Replacement mogrt that I built with a blendmode on the shape layer. I combined other controls like the Fill Color to change the look of that blendmode as it relates to the new media in Premiere.
You can't change the blendmode once you're in Premiere, but you could have a couple of versions if you needed it.
Here's a rad tutorial from the incomparable, EC Abrams on the feature.
Thanks again for the feature request!
