I'm a novice Blender user and I could use some advice on cleaning up some unintended mesh.
I'm working on a 3D model that I extracted from microscopy data. For this purpose the volumes are extracted from the raw data using a program called AVIZO. Then I exported the volumes to blender for smoothing and animation etc. I've been working on the model for a couple of months and I was adding the finishing touches when I found out that there was a lot of unintended mesh inside of the model. I think that I must have been sloppy with the "fill holes" or "fill" functions in an earlier version of the model.
I've deleted part of the unintended mesh by hand but it takes a lot of time. I'm wondering if you know a faster way of cleaning it up? Due to the pending deadline I don't have enough time to go back to an earlier version. I can provide some screenshots of the mesh if that helps.
I hope it's okay for me to ask such a question on this forum.
This is the screenshot of my mesh. As you can see there is a lot of stuff going on in the centerpart.
