Algorithmic released Substance Painter 2.3 version that brings a full Photoshop export path. Layers, masks and blending modes can now be transferred to Photoshop and each individual channel is exported in its own PSD.
Full Photoshop export means that all layers, folders, masks and blending modes can now be transferred to a Photoshop document with pixel perfect matching.
Each individual channel is exported in its own PSD to maintain the color space and bit depth of the original Substance Painter project.
Besides the Photoshop Export, this release brings with it several other highly requested features such as Custom Padding at export time, Custom Usage Mapping, an Improved Light Baking filter and a new clay shader.
