Plane with transparent textures looks odd insade volumetric box

Hello everyone. I’m expecting some odd problems when rendering a translucent image sequence inside a box with volumetric shaders simulating fog.

Here is a frame of the problem.

I’m using Switchlight Studio Ai to make the Pbr material from the footage.

I’m rendering with Cycles and I don’t know if there is an option that I’m missing to prevent that odd edge.

Thanks for the help.

This is a screenshot of the nodes.

Do you think it might work better if you used the Alpha value for your alpha?

I have no idea what is going in with those nodes, but the fact that you are mixing colors, then routing that into a float node raises red flags.

I tried that before, and it looks the same.

Found the solution. Just add 1 or 2 bounces to the Volume setting.

Render properties > Light Paths > Max Bounces > Volume.
