I am running tutorials through digital tutors. I selected the fire extinguisher and used a source particle and it turns into a block box. When I play it back the particles are just black and not separate from each other. Why is the pop solver node causing this to happen?

It may be related to your graphics hardware. Go ahead and put your machine specs in your signature.
Also press the D-KEY while your mouse is over the 3D window to bring up the display options. Make sure you have HDR rendering under the Effects tab enabled.

Trevor, did you find a solution to this issue? I'm experiencing exactly the same issue. I'm a total Houdini beginner (second tutorial). I did notice that in ‘Wireframe’ view, the particles are there, so I'm guessing it's something to do with how they're being rendered in my viewport?

I've checked my drivers are up to date etc. Any input would be appreciated!

While this may already have been figured out, I ran into this issue today and managed to fix it for myself. All I had to do was hit D (while hovering over viewport) and on the particles section of the geometry tab, make sure that display sprites was ticked off.
Oddly enough it only occurred when I plugged in a mocapbiped via a file merge into a geometry particle set-up, as opposed to a sphere.

Oh man, very appreciated that you share the solution with us. Thank you very much.
Have a nice day bro.

If you remove ‘shop_materialpath’ attribute on your source geometry, the sprite display issue should go away without having to explicitly disable sprite display.

Yeah dude <3 that all, love ya ma' men.

Yes disabling sprites in the Geometry tab of Display (D) settings works. Which is odd because my .obj doesn't appear to contain sprite attributes..
Veiwing in wireframe view also works

If you're using any of the test geometry as a base (pig head, rubber toy, tommy), they have a shop_materialpath defined. This is inherited by the particles, where it's assumed that the material must be a sprite shader. It's not. As such, it renders black.

Most of the test geometry nodes have an ‘add shader’ toggle, turn it off.

But what if i want to have texture of the instanced objects? Is good workflow to put an assemble sop to pack after my copytopints through which i have the objects instanced on the popnet, and i add a material sop after after unpacking?

Something like this bellow?
