bump map mirror
 
1 Attachment(s)
The big problem I have in completing the model is bump mapping and to be honest its really foxed me!! You will see attached stage 1 <bm_02> of the polygon model (bump maps included), however when I mirror the model with weld edges one side the bump map is inverted as it sould be and on the other side they are verted, I have checked the normals, I also tried to duplicate it on a 'minus' axis and then use the weld edge tool. I guess there must be something in the hypershader or do I need to redo the bump maps on the mirror side mirroring the bump maps???!!

try adding the bump map AFTER you mirror the model

Unfortunately that doesn't work......but it does seem to have something to do with the normals....as when you reverse them its fine but you can't weld the edges.....thanks for your reply anyway...

not too big on polys, sorry mate

Normals
 
I can solve it if I flip the normals on one side, however that leaves the seam down the middle? - HELP!!!

did you try freezing the mirrored side's transformations and then reverse normals?

Thank you very much for getting back to me....but I seem to have solved it. Because the body is made up of individual maps I needed to get into them and re-map inverting the bump map (if that makes sense) - I seem to have found a way to do this through the texture editor - GREAT!

Thanks once again....
