I never knew before that i had to add these properties in nifskope. Thank you very much. Then, after adding "NiAlphaProperty" to the "BSTriShape" should i add any further edits to these two for transparency ? or should i just proceed forward to add the "Alpha Test" property to the material file ? would that be sufficient for adding transparency to any object like window glasses, decals, broken objects etc. ? Thanks again for all your kind help.
