“Texture Painter” has just released with version 2.0 which introduces the ability to paint textures at real time using a projection system similar to version 1.0. UV seams are not an issue, textures can drive colour and MSR by default but can be used to control effects such as displacement, opacity and paint chipping. Options to use 8bit or 16 textures, as well as enabling physics on the paintable object are also implemented into the main blueprint, as are a series of restrictions to allow for a more accurate/consistent effects feedback.
Version 2.0 includes the previous version so you can still paint textures directly in the engine at high quality whenever you need.
