You have to stop the glass material to stop rendering as said in the video, when I do exactly what it said, my text won't show up and also sometimes I see only a part of my text and not all of it. And I only have the text font different than the one in the video because I don't have that one.
I'm sorry if this is not the correct section to post in, but it can be moved to the right section. Please help me out here with my problem.
Deflector3 is in front of the emitter (on the left) so it's bouncing particles back out immediately and they never get into the text
Deflector (the first one) is not long enough - it's hidden by the floor - and it's letting particles escape out the bottom.
There is so much Turbulence particles are escaping out the front and back (where there are no deflectors) so you are losing particles there too.
You could increase the rate of particles and increase the emit time since your text is longer than in the tutorial.
All that is why you are not seeing parts of the text, you only see it when you have a particle inside the text (that's what the Pyrocluster Volume tag is doing) and you don't really have enough particles and bunches are escaping so you get gaps in the letters.
you can't blur flat grey (not so you'd be able to see it anyway) and I don't see any blur under the text myself. You have shadows casting out of the one light but you don't have shadows turned on in the pyrocluster so it can't be a shadow. I think you might be seeing the light's specular on the floor as a blur - try turning specular off for both the lights and see if it looks better to you
