So here is a simple video to show you how to you would do that: The workflow for masking V-Ray Dirt applied to the diffuse color is similar but, since multiplying a cloud here would just make your entire object textured with a cloud with ambient occlusion in full, you want to reduce the AO by adding white. So, if you mutiply a simple yellow constant in a gamma correct node by a blue and white checker, you will get a green and yellow checker pattern: one value from/to another but, when you’re dealing with RGB data, you need to use the Input 3D, where the three dimensions represent R, G and B (these nodes can also be used with positional XYZ data). This may be a little confusing if you’re new to nodes that use 3D Inputs, so here is a brief rundown of these types of utilities.Īny color utility in Maya like the multiplyDivide and plusMinusAverage can take two values and multiply, divide, add, subtract, average, etc. If you leave the Operation of the plusMinusAverage on Sum, it will then add anything that’s above black to your V-Ray Dirt texture. The way you go about this in Maya is to mask the V-Ray Dirt texture with a plusMinusAverage node and another texture (the mask) plugged into another Input3D slot of that plusMinusAverage. Sometimes you want your AO to have a little more grittiness to it since it’s often used as a dirt map. Masking Ambient Occlusion in V-Ray for Maya

Of course you can use different workflows to add Dilation/Edge Padding to the map, but this is the easiest way to do it for this case, even if it is a bit roundabout. Next either export it as ".png" or use the quick-export function: Open the created PNG in PS and open up "Filter"->"xNormal"->"xN Dilation" The standard settings are sufficient. exr in photoshop and choose the "As Transparency" option.

To fix the texture issues in the baked map download "xNormal" here: You can also only bake the first UV Set, so make sure it's non-overlapping. The Render To Texture window is a lot reduced and most importantly the "Extend Edges" feature is missing producing bad texture seams. The steps below are needed if you have an older Maya/Arnold version. If you have multiple UV Sets input the name of the UV Set without overlapping, if it's the first UV Set leave it empty.Īrnold can only output ".exr" files when you are rendering textures, so before using it in our system you have to convert it to jpg. The resolution and Camera Samples have a high impact on both quality and render times.
This is important to fix black lines at the UV cuts. Make sure to select an output folder, set the resolution you need and that the "Extend Edges" box is checked. Make sure that the model is selected and then in the menu go to "Arnold"->"Utilities"->"Render Selection To Texture" If you have a newer version of Maya/Arnold than I (Maya 2017) then the pop up will look like the picture below and you can skip a couple of steps that I'm going through later. Those have the biggest impact on the quality and render time of the bake, 6 samples should be enough for most cases. The most important one however are the samples. We'll leave it at the standard settings for now. In the Attribute Editor you can adjust the properties of this material for different looks. In the new window click on "aiAmbientOcclusion" to assign the Arnold specific ambient occlusion material. Select the model, hold "Shift" and the right mouse button then select "Assign New Material" in the opening menu. Open a Scene with the model that is supposed to be baked.
