Hello! I am running a “Growing Vein” simulation in Houdini Apprentice and no matter how many lights I
put into the simulation. MPlay won't render out the View Port.
All that will be rendered is a quick 10 second black screen when I click “Render to Mplay”
For troubleshooting I have set the quantization to 32 bit float and have increased the gamma to 2.2 to see if those were the issues but to no avail. I set up a white light and increased the exposure/intensity to all hell, but also no luck in that regard.

I'm getting quite frustrated, and would greatly appreciate any help. File included is the most up to date file I've worked on. I'm using frame 193 to test while rendering.

I have a camera set up, 4 lights set up (the red lights are the “true” lights while the white is for testing)a grid for testing light reflections, and the simulation.
