hi there， as the pic i upload, when i switch texture , the right effect can not shows.
the first one texture has albedo channel pic and normal channel without pic but channel open and factor =0.5
the secend one texture has albedo channel pic and normal channel pic.
when i swith the texture, the secend one texture will remain normal channel pic for the first one
texture because the normal channel open without pic.
i use api.resetexture(zj,item) fro cleanning the last texture.
it works for every one which has successor , but if not ,the effection will remain.
