  • Different transparency levels in a PNG not showing on material

Hi,

I'm trying to use a PNG as a material on a basic plane mesh. Different parts of the PNG have different levels of alpha. For example most of the PNG is 50% alpha but some parts of it at are 90% alpha.

On the sphere in the shader editor it shows correctly (I can see the different levels of transparency on the sphere) but on the actual mesh in the 3D editor and in the running 3D scene the plane is all the same transparency.

Does anyone have any suggestions on what I'm doing wrong? It's driving me crazy.

Could you post some pictures?
Also, are you using a material? You have to create a new resource->standard material, assign the PNG as albedo, and set it as either alpha or scisor, then assign it to a mesh.

In order to control transparency with a greyscale you need to set "Alpha" on the "Transparent" section of the shader
