HOW TO: Get Photorealistic Render In Univah?

The Univah Film Engine was especially created to make life easier for 3D artist in the Lighting department.
Lighting is very important in achieving beautiful 3D renders. Whether your goal is to achieve realism or non-photo realistic results, lighting is one of the key factors in having a beautiful and believable render.

Here are some tips to get the best possible quality render in Univah.

1. Import Well Made & Well Textured 3D models into Univah and it will look great. Its that simple.
   Univah, by default, provides photorealistic lighting right out of the box, so that you no longer need to obtain a PHD in Lighting, to achieve excellent results. Just import your models and they will look great without you needing to add any additional lights to the scene.
2. Use High Resolution textures which are physically based. Use Normal maps. Use ambient Occlusion.

• Study Real World Images: In most 3D software, Directional Lights are used to simulate the Sun, and most artists add several Directional Lights to their scene to achieve the result of their liking. However, that is not how real life works. In the real world, we have just one very powerful sun. One sun is more than enough to light up over half the planet, providing Day light in parts of the world while other parts of the planet experience Night.
  
  In Univah, to keep lighting realistic, we allow the user to have just one very powerful sun. That’s it.
  In Univah, we strongly utilize the power of the sun and it is our main power source, just as it is in real life.
  In the real world, during the day, we rely on the sun to light up our exteriors and also our interiors. During the day, you should not need to add several directional lights. Just one sun. When we enter our homes during the day, If our home has plenty of windows, then our home will be well lit inside by the power of the sun alone without needing to turn on any light bulbs in our home. In Univah, our lighting system works the same way. If your home does not have many windows or has blinds, then even during the day, the home may appear dark which then will mean you would have to turn on some lights in your home to add brightness. So in Univah, you can add spot lights to simulate a lamp, ceiling recessed lights. You can also use point lights for varying light effects. After adding the number of spot or point lights needed to properly illuminate your interior, then we use global illumination.
  
  The goal is to use as few lights as possible to achieve the best, true to life results as possible.
  If we have done our job, then even in low light settings, your render will still look realistic.
