#Types of lights in arnold for maya how to#

Set the normal direction to 3 if all the particles are moving away from the light. Set it to 2 if the particles are passing in-front of the lights, or do not move. Set it to 1 if the particles are moving towards your light sources. To maximize particle illumination set the normal direction to a new value. Use either Streak, Multi-Streak, point, and/or Multi-point. If you would like your particles ton drift out of a light source, or appear to fade out of one, turn on some render types. You can also you ray tracing to create shadows, or just turn on depth shadows. You have to use ray tracing with reflections and refractions. Without these settings turned on, you will unable to see anything reflective/refractive. Go to render stats, select your object, and turn on visible in reflections, visible in refractions, and cast shadows. Rendering Reflective Objects and Particles If you are exporting your images as bump, normals, EXRs, or HDRs, you'll need to change the color-space to RAW.You can change the overall color-space of your files under the preferences and color management tabs.

These come with custom AOVs and IDSs, more easier control over sub surface scattering, and more material presets. There are also some material presets in ai that you can use for objects.ĪiShaders are open source shaders built for Arnold. By increasing the samples on the area light, you can create realistic renders more easily.Ī istandard materials work great when you wish to create your own custom materials. By doing this, you can diagnose renders.Īrea lights can be used to improve lighting, but also extend render times. In the render view you can use the masking tools to filter out layers of your render. This will allow you to have more control over your composition.

This is a compressed file format that Arnold uses, so your textures will load faster.ĪOVs(Arbitrary Output Variables), let you render out any shading network into images. This ray depth works well with glass objects.Īrnold gives you the option of using TX texture files. Refraction ray depth is the number of times a ray will be refracted. Diffuse ray depth will increment the light rays bouncing around in the scene. However, this will also lead to longer render times. Using Ray Depth for interior rooms and areas is recommended. Some solid base-lines for samples to use are: AA = 7-11, Diffuse = 2, Glossy = 2, Refraction = 2, SSS =2.

If the camera's AA samples equal 4, then the total samples will equal 16. The actual number of samples, is the square of the input value. The more samples the better, but the longer the render time. Make sure your Arnold Plugin is turned on, otherwise it will not appear in Maya. If you would like to read more on Arnold visit the Arnold render guide: HERE. Hopefully this help you render your VFX and scene more effectively.

We'll talk about some ticks you can use while rendering in Arnold, and also how to diagnose for errors and aliasing. Arnold is a hugely useful render engine, and in Maya it's been implemented as one of the main ones.
