'There is a way to put some line in the product to disable the smoothing even in the case when the smoothing option in firefly is checked on?' Sorry, kawecki. I just saw that. I mentioned it in the post above, but here's the hack in detail. This is what a P5 file looks like - at the end of the body part, after the channels. --------------------------------------------- endPoint -0.171 0.401 0.098 origin 0 0 -0.087 orientation 0 0 0 displayOrigin 0 displayMode USEPARENT customMaterial 0 locked 0 backfaceCull 0 visibleInReflections 1 visibleInRender 1 displacementBounds 0 shadingRate 0.2 smoothPolys 0 } -------------------------------- Add the line smoothPolys 0 before the closing brace. You don't need the displacement or shading lines, just the smooth polys one. This is if you don't have P5. If you do have it, switch 'smooth ploys' off in properties and save the file, then change the version to 4.01 for P4/PP users. mac
