1. What are the supported geometric primitives?

All Softimage geometries are supported: ICE Particles, polygons, subdivision surfaces, NURBS, curves, particles, hair. Hair instancing and stand-ins are also supported. Softimage hair and ICE strands that uses thin curves will be rendered using 3Delight's ultra efficient RiCurves. Subdivision surfaces, as well as other curved geometries, are rendered perfectly smooth to sub-pixel accuracy.

2. Does 3Delight for Softimage supports ICE features ? What about Volumics ?

ICE volumes are supported along with ICE particles and strands. Some parameters in the ICE volumes are still unsupported. They will be if and when requested.

Volumics are supported but are lacking the "shards" feature. It will be added in the next update that will be made available soon.

3. Does 3Delight for Softimage provides physically plausible materials ?

Yes, three physically plausible materials are provided: 3Delight Material, 3Delight Skin and 3Delight Glass.

4. Which standard Softimage materials are supported?

All material nodes (architectural, phong, etc) are supported as well as the most usefull utility nodes. All in all, about 225 shader nodes are supported.

5. Does 3Delight for Softimage supports global illumination?

Yes, a unique progressive path-tracing algorithm provides  complete GI support. One bounce point-based global illumination is also supported.

6. Is re-lighting supported ?

Yes, re-lighting is supported in the form of rapid re-rendering in the Render View. Camera, lights and materials can be modified and results are update clost to real-time.

7. Does 3Delight for Softimage come with a shader builder?

3Delight for Softimage fully support Softimage's Render Tree, both with Softimage nodes and the RenderMan shader nodes that we provide. This makes it possible to build complete RenderMan shaders using the familiar user interface of the Render Tree. It is also possible to extend the functionality of the Render Tree with RenderMan Shading Language programming (new shader nodes can be added by providing a SPDL file along with a RSL file).

8. How to set up a rendering pipeline on a render farm?

There is no difference compared to the Softimage + Mental Ray workflow: after selecting 3Delight as the renderer, by launching XSIBatch with or without a dispatcher.

9. Can 3Delight for Softimage export RIB files?

Yes, in addition to its direct rendering capability, 3Delight for Softimage can export RIB in two different modes: monolithic or archive-based. RIB files can then be rendered using 3Delight Standalone (or any other RenderMan-compliant renderer).

10. What are the advantages of exporting RIBs compared to the XSIbatch workflow for rendering?

In addition to providing added versatility (of the encapsulated RIB file), rendering RIB files will be more memory efficient since there is no need to load Softimage and other plug-ins. One can save at least 1Gig of memory and substantially more for large scenes.

11. What are the main advantages of 3Delight over Mental Ray?

Rendering of complex scenes, with hair/fur, displacements, motion-blur and depth of field will render significantly faster, use less memory and provide better quality. Also, 3Delight can render very large scenes without hiccup. A short list of benefits is also presented at the beginning of the Overview page.

12. Should I enable hyper-threading for 3Delight to perform at its best?

On the more recent CPUs (such as the Intel Core i7) some of our clients have reported performance gains of up to 30%. But on older CPUs the gains were negligible, if any. So you may have to do rendering tests with and without hyper-threading on your computer and decide for yourself. Also consider that if hyper-threading is enabled, rendering will consume more memory and if you dont have enough, it may start to slow things down. So, if you encounter a situation where you are running low on memory and your computer starts swapping too much during rendering, you may want to try disabling hyper-threading (or as effectively and more simply tell 3Delight through the rendering options to use only half the cores during rendering).

13. Can I use the free license for commercial work?

Yes.

14. I have a few more licensing or pricing related questions, where should I ask?
