hi,guys

 

I want to use normalmap for my model, so i need tangent data in my .pod file.

 

but pvrgeopod will tell me "tangent-space generation failed" with some model.

 

and sometimes it work just fine , but give me wrong tangent data (all tangent data was simple zero--0.00000000000) :(

 

any idea?

 

dear Gordon, can you help me? i have lots of models need tangent data ...

 

should I mail you a model file for test ? thanks.

 

I run latest pvrgeopod plugin with 3d max 9 on windows vista.

 

and finally, please forgive me for my poor english :)

Sorry for not getting back to you sooner - if you can email a model to devtech@imgtec.com then we’ll have a look at it.
