I'm trying to get this soft light reflections like in this reference photo on my 3D model, and I don't know how. How can I achieve this. By this I mean, for example look at bowling ball it's has this like reflections of lights in a very soft mannerand also the reflection of a pin . It's soft but very clear and it's still looks like a bowling ball. Pics of node setup would be very much appreciated and any other pointers on making my model look exactly or close to my reference photo. I only have my models already arranged. And I played around with some nodes not getting what I want.
Light Setup and Shaders
In order to achieve a similar look, the most crucial part is setting up the lights (as always). Add 3 large Area Lights along with a soft rounded backdrop (typically used for classic studio photography) to the scene in order to get similar reflections as well as soft shadows:
The larger the area lights, the softer the resulting shadow on the ground
To replicate the shader(s), all you have to do is figuring out a proper rougness value and set the reflection (specular) to
1. Tipp: The roughness value for plastic is about
0.2 - 0.3 according to the manual:
Roughness set to
0.01 (left) vs. Roughness set to
Fake Motion Blur
You can fake the Motion Blur on top of the pins, by splitting up the scene into View Layers (backdrop, pins and bowling ball in this case) which allows to add the blur only to the pins in your favorite raster graphics editor of choice or even in Blender's Compositor:
Overview of potential view layers - All objects are set to 'Indirect only' for the 'backdrop layer' per collection and the background is set to 'transparent' for both object layers
If the later is an option, I'd suggest use a Directional Blur node on the Pin Layer also and also blur the result slightly, see: How to manually achieve a motion blur effect on a object in the compositor?
Real Motion Blur
In order to get realistic Motion Blur you would have to move/animate the pins in the scene and enable Motion Blur under Render Properties > Motion Blur and play with the shutter setting, which gets you a more realistic and especially photographic result:
To achieve this effect, Set metallicness to 1 and roughness to anything between 0.3 and 0.45, as anything greater than that would have no reflections. and there you have it, soft reflections on the surface. Here are the nodes:
And here is the render result. (Sorry it isn't perfect as my computer literally burned while rendering this.)
Please note that you can change the roughness value to whatever you like, But I would recommend going with something between 0.3 and 0.45.
As for the lighting effect, you would probably have to do it in photoshop. If you like, you can use the compositor nodes, here are the nodes:
Hope it helps.
