In the next tutorial I will try to explain what parameters you need to control in order to obtain realistic caustic effects with 3ds max and vray. Rise Of Nations Addon there. Open the caustics start scene that you will find in this zip file. As you can see, the glass material is already prepared reflect 2. IOR 1. 4. 4 Affect shadows checked. First, go to the Vray caustics rollout and activate it by checking the box next to it. If you render it at this stage you will end up with something like this The caustics effects are already visible but they have a fake look and lack definition. The most important parameter that we need to adjust is the caustics subdivisions that are emitted by the light. For this, you need to right click on the direct light, choose vray properties and increase the caustics subdivisions from 1.

Now lets see what other parameters doIf we change the search distance parameter to 0. As it can easily be observed, smaller values produce much sharper caustics but a lot more noisy. Higher values result in smoother caustic effects, but at the same time the higher the values, the blurrier they get. After several tests, I am happy with a search distance value of 0. The caustics still look a bit noisy, but we will try to adjust this by tweaking the max density parameter. Gangland Game Full Version. Max density is probably the trickiest parameter, and if you dont understand how it really works, you can end up with unexpected and undesired results. First, lets do a test increase the max density from 0 to 1 and look what happens Where did all the caustic effects go Take a look at the following diagrams If max density is greater than 0, when vray needs to store a new photon, it will look if there is another photon within the radius specified by this parameter. If it finds one, it will just add the energy to the one in the map, in order to keep the photon map at a smaller size case 2 of the diagram. If the area is too large the end result will look like there are no caustics in the rendering. If no other photon is found within that radius, the new photon will be stored in the photon map case 1 of the diagram. After doing some tests, I think that a value of 0. In order to realize just how tricky this max density can be, leave it at 0. You would expect better results, right WRONG The result looks exactly like the one with max density set to 1. Basically by increasing the caustics subdivisions we ended up with more photons acting like case 2 of the diagram. Other parameters Multiplier it makes the caustics brighter if increased, or less bright if a value lower than 1 is assigned to it. In theory you should leave it at 1 since it is supposed to give physically correct results. Max photons somewhat similar to search distance, but instead of using the distance between photons to interpolate, it uses a higher or a lower number of photons. Mode works almost like the irradiance map. You can choose new map to calculate it again, or you can save it once you are happy with it and load it later for further renderings. Another important factor to keep in mind is that the looks of the caustics depend a lot on the geometry of the objects that cast them. For example if you want to render a swimming pool with caustics you need to model a realistic water surface or at least a really good displacement map, otherwise it will not look natural.
