painting on a model object

[d1820]

I want to paint on a bump map to my object that will look like wrinkles in a fabric. My question is when i export this bak out to an OBJ file wht does the bump map i just painted come out as? Is it saved off as a bmp file or is the bump map info stored in the OBJ file so as when i load it into my rendering engine and add a texture to it the bump map i drew on will show up without having to load a bump map image?

Any insight on this would help so much thanks

The best way to export it once painted is to make sure that it's the texture that's currently wrapped onto the model and the press Tool>Export to export the model. The current texture will receive several adjustments for better cross-application compatibility, and will be saved as a BMP of the same name as the model.

You can then take the BMP into your application and apply it to the model there using its methods for adding a bump map to a material.

There is no way to simply load the model back into your app and have all textures applied automatically. That's because all programs handle material channels differently.
