• Understanding Lights in Maya - Part 4 Software: Maya Author: Aziz Contact: aziz3d(at)clubsrk(dot)com Hello guys and welcome to the last part of the 'Understanding Lights In Maya' tutorial series. In this tutorial, we will light up an interior scene which should help you to understand how lights works and how to set up lights to illuminate any interior scene. Ok let's start working. 1 - Start by downloading this scene (at the bottom of this tutorial) or perhaps use your own scene. Once opened, create two Area Lights. 2 - Fix them onto the windows but with a bit of a gap between the windows and lights. 3 - Ok it's time to simulate sunlight. For the purpose of this tutorial, we will use Directional Light since it will work fine in such situation. Create a Directional Light and then place it similar to the image below. Make sure that light is passing through the window inside of the room. 4 - Fix your camera inside the room and do a test render. 5 - Once you setup your lights and are happy with the placements of lights, hit render and you should see a blown and washed-out image. 6 - Let's start working on the lights. Select the Area Lights one by one and apply the same setting for both. 7 - Select Directional light and activate shadows. 8 - Now in the Render Settings, apply the same settings as seen in the image below. 9 - With these settings set, hit render and you should see a very dark image with exception to the lights from directional light. 10 - Now select one of your Area Lights and turn on Emit Photons and do the same settings or adjust it accordingly to your scene size. Photons are scene dependent, if you have a larger scene, a low amount of photons wont work until you increase them. 11 - In Render Settings of the mental ray tab, choose Mitchell for Multi-Pixel Filtering. 12 - Turn on Final Gathering and do the rest as seen on the image below. 13 - With these settings set, hit render. Your result might be different from mine because I am using a texture on the floor which also caused my emit photons to emit the same color of my floor texture. 14 - Apply textures to your entire scene and when you hit render, you will see a very very dark image if you are dealing with darker wood textures or something similar. As you can see in the above image, the wood texture for the floor is pretty dark. If I apply the texture to the entire room, I am sure I will get a pretty dark result. You might be asking why this is and what is the cause of this? Well the answer is pretty simple. The texture which you are applying to the objects, the material itself has Photonic Attributes. This means the material will emit Photons of the same color as our texture in the scene -- which explains why we are getting a darker result. To solve this problem, select your material where the texture is set for the walls and then hit CTRL+A to open attributes editor. Expand the mental ray tab and scroll down a bit to uncheck 'Drive From Maya' check box, and then click on 'Take Settings From Maya'. Now if you look in the Color slot, our texture is connected which is why it's emitting dark photons. Right click on it and in the popup menu, chose break connections and set the color to something brighter as seen in the image below. 15 - Hit render and this time you should see a pretty nice and interesting result. Here is my final rendered image. If you would like to see my settings, below is my end scene which you can download. Congratulations -- you have successfully completed this series of tutorials. I hope this has helped you out to learn more about lights in Maya. if you still have any comments, suggestions, feedbacks, questions please feel free to write me at: aziz3d(at)clubsrk(dot)com Scene Files: Start Scene End Scene Other Parts of Tutorials: Understanding Lights in Maya - Part 1 Understanding Lights in Maya - Part 2 Understanding Lights in Maya - Part 3

  • One of the best, extra supa cool tutorial that I have come across. Im a regulay visitor of 3dtotal.com, cgsociety.org, highend3d.com, etc etc.....I had not been so close to a tutorial like this before. Very neatly explained for self learners and self motivators like me. I really appreciate your hard work in spending lots of patience in describing the whole process of lighting in Maya. Normaly their are a 1000 reference and tutorials for MAX rendering and lighting. But you have come up with a good posibility of resource for maya users, I request if you could post this tutorial in www.game-artist.net which could help thousands of young talents who are only friendly with Maya applications. Plz post in few links where I can find such tutorials regarding texturing and Modeling. Cheers to Aziz...!!!!!!!! Your tutorial inspire me.

  • This tutorial helped me learn much about lights and shadows as well mild level of texturing. Was wondering if you or anyone else here could have an indepth guide on making a simple 3d organic model with riggings and from simple animation. I am pretty much a new comer to this program and am still learning the ropes. I am taking classes based on maya but since the classes tend to rush on with concepts and ideas I am not able to grasp it good enough. So far for a newcomer to me this guide has been really help ful. Keep it up.
