Hello everyoane. What settings should to apply to the light point to create in blender a scene light this? I come with a past in Cinema 4D, there was very easy, just set the visible light to Volumetric and set the intensity, but how does this work in blender? I have searching for an answer here, but nothing matches with what I need... Kind Regards!
Thank you for stating your question clearly. You need to setup a world environment mist. The rendered light volume in Cycles doesn´t work with (noise/volumes)on the light. It works with noise /volumes on the space (Enviroment) like in the real world. Make a cube. Assign a shader to it. Edit the shader. Delete diffuse node, CTRL+Shift A, search for principled volume. Attach it to the Material output on the VOLUME input connector. Shift+A, select NOISE. Plug that NOISE into the DENSITY connector of the principled volume shader. Delete all lights in the scene. Make the world from the world property tab: black color. Drive your camera inside the box you previously created and that you´ve assigned the principled volume shader. Inside that box and with the camera looking through, create a ppoint light. Give it energy of 100. And continue to drop it down by half on each render test: (50, 25, 12, 7, 3.5...etc) Until your light energy is appropiate for the effect you´re looking for.
