i made a model with xsi and then exported the way ti said to in the tut for mshex and when i look at the msh in the mesh viewer and nothing appears. did i skip a step or do something wrong with exporting

well, you should know if youve skipped a step yourself the best, shouldnt you?
in case you did, tell us what probelm you have with it, skipping steps leads in most cases to an undesierably result.

well i made the model in blender and exported it to obj the imported to xsi mod tools 7.5 and the model shows up on both tools but when i export and convert to msh and view it with the swbf msh viewer nothing shows up and i load it more then once and get the same thing

he might be having a problem with textures make sure all of your objects faces have textures that can mess u up in mshex

they all have textures cuz i uv maped it in blender before exporting and importing to xsi

what is the name of your model exactly?

base2.xsi before converting

Edit: i figured it out, i kept forgetting to middle click on the null on the explorer before exporting
