3DS models - some faces transparent

Hi,

I downloaded some 3DS models from the 3DCafe to load into blitz and play around with. Up till now I'd used a model that came with Blitz and all was fine.

My problem is that some of the surfaces are transparent when they shouldn't be. using 'EntityFX HandleNo,16' seems to fix that but then the model does not light correctly.

What in blue blazes am I doing wrong?

Sounds like some of the faces are inverted, facing the wrong way.

So I may not be 'doing it wrong?'! Oh Blast. I had kinda hoped I was. :(

maybe you could fix it in 3dsmax using a normals-modifier and set to uniform normals. Sometimes, when the lightning is faulty it helps when the model is exported as DWG and then reimported. fact is 3ds is not an exact science.

I don't have 3dsmax. Thanks for the advice chaps. It does indeed look like some triangles are about faced. Double blast and drat.
