Hi,

I am loading a large dataset using remote rendering. I’m applying a opacity transfer function to highlight zones of interest, but I don’t see anything changing on screen. Maybe it is just too dark or maybe is not even loading correctly. This is what I got:

When I switch the data representation to slices or points it shows something

Maybe it is not a volume, but the full dataset is a tiff stack and I have had similar datasets rendered correctly in paraview.

One thing I did was pre processing the images increasing their brightness and contrast one by one using a batch script in “imagemagick”. I loaded some of the new images on paraview and I was able to see them correctly. But when loading all of them as a volume, nothing is displayed.

Do you suggest any combination of paraview filters I can try to improve my results?

Thanks for the help in advance.
