When loading Substance textures, they do not always show up.
After messing around, I found that if I adjust the SEED Value up (off of zero) and then back down (to zero), the texture appears. Sometimes, reloading a project, Substance textures reset to white and need to have the SEED value shaken again to appear. After one re-save under a new project name, they seem to load properly.
Using Studio 8.4.38
Thanks for being Awesome.
