Use a layer with effects as a texture for a particle system
I want to use a layer with effects on it as a texture for a particle system, without using an embedded comp. I know that by using a grade layer, you can "flatten" all layers underneath, the problem is, that a particle system does not accept a grade layer as a texture source. I do not want to use an embedded comp because that would mean that I can't export the comp anymore. Is there any way around using an embedded comp?
I am using Hitfilm 4 Pro.
