Hi guys never posted before, hope you are all doing well. To start off im going to say i never had this problem before and its quite frustrating, basically i modeled a scene in maya did some sculpting , retopo back to maya, unwrapped everything and since it is a little environment scene and has different parts to it i assigned different materials to it in maya so when i import it into Substance Painter ill get a bunch of different texture sets ive always been doing this with my models and never had a problem. this time in painter everything looks fine you can see all the texture sets that were created at the end when everything was finished i uploaded to sketchfab as usual but it shows only 1 material available for edit in material tab and there should be a lot of them since i applied them in maya and they displayed fine in substance. it makes it impossible for me to apply my textures in the editor due to all those materials missing. never happened before every other time it displayed all the materials (texture sets) properly and i was able to upload everything successfully, ive got some screen shots here so you guys can take a look at it, sorry im not great at explaining and my english is not my primary language but i hope you can understand what im talking about, hopefully some of you can help out ps- i also added a picture of a well that i made a while ago showing example of what the material tab should look like for your reference. have a nice day.
