When a model is physically rendered, the lighting in an interior scene poses challenges. One of these issues can be noise that will distract from your rendering and make it difficult to see what you’re working on.
When doing physically plausible rending things get tricky especially with interiors but one thing i have noticed when making this type off final product which makes life so much easier its understanding how light works!
The use of light portals in Blender 2.75 can help reduce noise and improve scene rendering times by up to 50% when working on interior renders, according to the software’s creators at blenderHQ! The author walks you through how these adjustments work step-by-step with simple instructions even if you’re not familiar with this feature yet.
Interior scenes in Cycles are notorious for being noisy. Here’s a quick tip to help clear things up more quickly.
Depending on the type of interiors, they can be handled more efficiently by using a higher sampling rate. This is because with different types there are varying complexities to look at and capture which could take up valuable time when sampled at lower resolutions or low-quality textures as it would appear less detailed than an object intricately designed with lots going on in every corner like what we see here for example…
Pervious to Blender version 2.75, there was no such thing as a light portal! This was unfortunate because it offers great way for you can “refocus” your sampling in the scene and really bring out those details with some help from this new feature.
To create one just go into edit mode then select Render > Light Portal or hit F12 on PC turning off shadows first before adding them if needed after that choose an area where lighting conditions will be similar across all corners making sure not too much detail gets lost by having sharp contrast between areas.
Blender’s Cycles renderer is a path tracer, which means it can only render light portals on the environment and not inside of models. This allows you to easily clean up noise in your interior renders by managing samples more effectively with these Light Portal nodes; allowing for better quality without too much work!
