help needs in bump map


Recommended Posts

Some of your face are having normals in the opposite direction (iie away from cam) and some are towards the cam. so you are getting different bumps on different faces. if you can identify the elements with opposite normals, just select by 'face' sub-element edit mesh modifier and click 'flip normals'.


The plines done clockwise and extruded in acad do have negative normals. thus applies to all the MIRRORED entities too. So try to make it Anti-Clockwise. BTW it is for exteriors :)
