I love shaders, I really love shaders. But look, I have a few problems with them. The first thing I hate is they are windows only. I mean - come on! Why can't they be used in other exporters yet? This is probably my biggest problem (related to shaders ofc) ! Okay, second thing - there's a option to apply shader to the whole frame in frame properies. I wish I could do that also in application properties, I mean applying shaders to the whole application. I know you can create a global event "start of frame" -> "set frame effect (or smth)" but yeah, I would prefer it to be in appliaction properties right away. Okay, the last thing I want you to add ability to add more than one shader per object / layer / frame / (application). I sometimes find it really annoying. For example, when I want to give an object a shader bloom and at the same time color adjust .
So yeah that's all I wanted to suggest.
