Tips for perfect photorealistic 3D rendering

Countless factors are to be considered when it comes to product rendering for achieving believable and the best results. Getting the lighting and modelling correct is just a part of the process. There are certain product rendering tips that are really effective. Let’s scrutinize.

product 3d rendering


  1. Start with a decent reference material

  2. In case if you a modeling something that exists already, gather maximum possible reference material to get the needed views from the top, side and front. This will make sure that the model looks perfect from all the angles. Always take care of the proportions as if you get them wrong, the final render would not appear to be photorealistic. Professional 3d rendering companies always keep this in mind.

  3. Scale to the real world

  4. Set the scene units correctly and model to the scale of real world for assuring photorealistic rendering. This is important to make sure that the scene lighting behaves just as in case of real life. This helps in future-proofing as well when you need to introduce any sort of dynamics later on, like that of cloth or liquid, that depends on your actual units for setting up correctly.

  5. Mesh should be kept clean

  6. It’s always good to assure that the mesh is clean as well as comparatively low-poly. This is one of the proven product rendering techniques and helps in keeping the scene size lower thus making the complex models easily workable. Also, you model will be appropriate for any scenario. TurboSmooth modifier is a great option to choose.

  7. Make the hard edges softer

  8. There are rarely any sharp edges for the actual real-world objects. So, by softening the hard edges, you can make the models look realistic. Also, when illuminated, these edges will be nicely highlighted. However, chamfering them can be a bit tedious when the models to work with are complex.

  9. Pay attention to even the minutest of details

  10. Small details in 3D modeling have the capacity to alter the whole level of perception. It may tempt you to proceed with the shortcuts and ignore small details that are not clearly or easily visible. These minutest details in fact are highly influential in tricking the viewers to make them believe that the render is real.

  11. When needed, make use of override materials

  12. When a product is rendered in a studio, images can be overpowered by the background colour. This can affect the reflection, shadow colours, GI and refraction in 3d rendering and visualization. This may be fine in certain cases but a lot of exceptions are there. The effect can be manipulated by make using of a VrayOverrideMtl which can be really helpful.

  13. Render in slots

  14. When you render in passes, time can be saved and quality can be improved. It may take some time for setting up the scene but when you are rendering images with higher resolutions, rendering of different phases can be done simultaneously which is very beneficial.
