You usually enable them when your model has really weird and blobby shading⤶ This is only really used when your model is capable of being applied with expensive tangents.⤶ <note>This will **uncompress** your vertex data with 32bit, **default** (compressed) is 8bit</note> ## Guide We need to add **RenderMeshMarkup** to the mesh you want to apply it to: <upload src="b0065/8dabd05117b3c07.png" size="6306" name="search.png" /> Then we need to check **"Use Expensive Tangents"**: <upload src="b0065/8dabd059671a1be.png" size="11179" name="tangents.png" /> <upload src="b0065/8dabd0ad2b404ed.png" size="334183" name="beforeafter.png" /> Look at that!
