Apparently the transparency property has been lost when I imported the obj. I tried to change the opacity but it will apply on the whole object instead of the only surface.
Please help.
Any method to ungroup the imported object? Thanks
Please help! Still not found any ways to resolve. 
Hi @Louis_Wong,
Could you share the model you’d like to use in CoSpaces with us? We’ll take a closer look at the model and try to see if we can support its transparent material
