Digital Clothing for Decentraland's avatars

[maduaryam]

Hello every one,

I am designing clothes for avatars with Clo3D and Marvelous Designer , I had some questions, thank you for guiding me:
1- I would like to familiarize myself with Decentraland platform's avatar system and its requirements for wearables.
2- Where can I Import my wearable item and apply it to the avatar to check if my wearable item is placed correctly on the avatar and where can I use the preview mode in Decentraland 's Builder to check if my wearable item fits properly on the avatar? Decentraland platform is compatible with which format: OBJ or FBX or GLTF? which template? I must export my 3D model in GLTF format or GLB format. which 3D file formats?
3- What is Decentraland development environment so that I can test my wearable to ensure it works as intended?
what is the address website of Decentraland 's marketplace for submitting my wearable so that others can purchase wearable and use them on their avatars?

4- To design digital clothes suitable for Metaverse, between Blender, Marvelous Designer,3D max, Autodesk Maya, ZBrush, and Substance Painter, which software do designers use to design their digital clothes for Metaverse avatars? which software is more suitable, more common, and more practical?

Thank you for guiding me.
