Hi @Jayb I did in a way. When I began my visual abillities were really, really poor. Now I can at least without entering TGS visualize things pretty well. Without TGS my current visual ability is sort of like this, it’s a bit better than that but as close as I were able to find with a quick Google search:
Steam Community :: :: Grainy...
In TGS it’s sort of look lile this:

Now I used the hermetic approach by Franz Bardon - innitiation into hermetics, but also this book -
where they have an excellent visualization exercise. I can’t reveal it because of copyright. Now, I found when trying and feeling the: wanting to see more, or when almost straining to see something inside the minds eye.
I tensed up more, and thereby hampering the visuals while in the trance state. So one part in successful visualization is: relaxation, the second key component is that in the beginning, it’s important to start at really basic level - like visualize simple 2d images on a white surface and then as you get better at it, move on to more complex imagery. Your initial benchmark should to be able to hold a still image for 5 minutes, trust that’s hard enough for most people as your minds tends to get bored, and if you get bored you can’t concentrate and you fail.
So a recap: relax, and find a way to enter trance or state that’s akin to sleep where your mind is awake but your body is asleep - plenty of material to be found on how to do that, from there try to a hold an image for about 5 minutes and keep at it until
It clears up or reaches a satisfactory quality. Make sure are relaxed and frustrated as mood swings can impact your visual quality, frustration especially.
For me it’s usually easier to visualize with my eyes open, don’t know why. You can try that if you wish.
Now, regarding my starting point, you can get successful with imagination in evocation: when you evoke you use your intuition, and your feeling, associations, your ability to sense the entity, then send your intention with the evocation through their sigil and wait for the result. However the results of evocations and other things, will usually improve if you are able to visualize it - along with feeling it. Yes, it’s more important to feel rather than see something, as seeing it can enhance the sensation of feeling it, or vice verse - so one can and usually will feed the other ability, thereby making it more real to you and in turn stopping doubt from planting it’a seeds inside of you.
My results before improving visual abilities were good, but not good enough according to me. One example I tried to help a family member of a dear friend with a rather serious illness and in part Inwas successful. Meaning I cured two out of three bacterial infections whereas the third was not present at the time of the evocation meant to cure them, this wasn’t as much visualized as it was felt and imagined of how they were able to walk freely, and without hindereance along with appearing healthy.
