The color management in Softimage will at the moment only affect the display in SItoA, for textures the only supported workflow is to have your linear images stored in an HDR format (.exr.
How can I avoid my procedural textures from swimming? Keep in mind that doing this will override your objects normal visibility settings. In any case, you can also apply an Arnold visibility property to an object, partition or group which has all the visibility options that Arnold natively supports in it. It's a bit of a hack but it's as good as it can be done. Take into account the checkbox for "Reflection Visible" controls normal/sharp reflections, and "Reflection Caster" controls glossy visibility. Yes, Arnold will read the visibility options Softimage already has. Can I use the normal visibility properties on my objects? The skydome_light will be most of the time the best and fastest way of achieving IBL, in both speed and noise than other methods like using a sky shader.įor a more detailed description of the subject please see the IBL page. Direct specular are reflections coming from regular light sources (spot/point/area/distant lights), and indirect specular are reflections coming from another object or an environment map. You also have separate controls to adjust the intensity of the direct and indirect specular reflections. In the limit, a value of 0 will give you perfectly sharp mirror reflection. The lower the value the sharper the reflection. The "Roughness" parameter will control how blurry your reflections are. In the specular section, increase the "Scale" parameter.
How can I do glossy reflections using the Arnold standard shader? How can I hide polygons from the renderĬurrently, SItoA only supports clusters with visibility property (which you can create from Get > Property > Polygon Cluster Visibility). Where can I find Arnold specific shaders?Īll the shaders SItoA comes with are accessible from the bottom of the "Nodes" menu in the rendertree, they are also available by going to Get > Material > Arnold Shaders. For a list of supported Softimage shaders please see the Shaders section. No, the Architectural shader isn't supported yet but Arnold comes with its own general-purpose shader called "Standard" which is quite similar. For more information about SitoA-specific commands please see the SItoACommands. There is also a command to flush the scene SITOA_DestroyScene() and textures SITOA_FlushTextures(). You can adjust the Scene Rebuild Mode from Auto to Always.
#Softimage 3d model black spots update
Sometimes the render-region doesn't update when I change various settings in my scene, how can I force it to refresh? For issues to do with rendering with Arnold in general, see the Arnold Rendering FAQ. These issues are specific to the use of the SItoA plug-in, and do not relate to features of the Arnold renderer itself.
