Sceneform SFB Opacity Issue #67

Open chiaolinghong3d opened 6 years ago

chiaolinghong3d commented 6 years ago

The opacity in Material parameter does not seem to change anything when I set it to 0 or 0.5. I've tried on both obj and fbx, both don't seem to change anything. reference

Thanks!

@chiaolinghong3d - In the current release, for objs, there is a bug where the opacity is only functional if your underlying obj asset is not fully opaque.

As a workaround, if you switch the "d" value for the StingrayPBS1SG material in your mtl file such that it's not 1 or 0, you should be able to modify the opacity value in your sfa and it should control how opaque your model is.

For me doing this "d" value made my transparency work, setting to .99 instead of 1 it is mostly perfect.

@edencorbin where exactly is the "d" value?
