This webinar will be a functional overview of the application, showing its basic workflow. The following webinars will go into more detail of working with the application, especially using the sophisticated material layering.

During the webinar many questions were asked that we promised to answer, so you can find the questions along with the answers below.

Q: What does the whitepoint do?
A: Whitepoint is a color that will be mapped to “white” on output, i.e. an incoming color of this hue/saturation will be mapped to grayscale, but its intensity will remain unchanged. For example in a lighting condition where the light is either reddish because there are lots of light bulbs that emit a tinted light you can compensate that white colors do not appear as orange but as white.

Q: Is it possible to apply materials directly to layers?
A: Yes

Q: Is it possible using iray with sketchup?
A: Please check out:

Q: Are there in Iray preset materials?
A: There are loads of MDL presets in Iray, see later, vMaterials, … See for example: This will de demoed.

Q: How do I create custom MDL materials?
A: Materials can be layered to any degree of complexity, allowing you to add stickers on top of other materials or add a layer of dirt on an otherwise clean material.

Q: How do you manage the UV mapping in Iray?
A: Iray receives the texture mapping being applied by Rhino. So any UV mapping done in Rhino will propagate to Iray. (There is currently a bug in IFR that supports only Texture channel one, this will be fixed in the upcoming release of Iray for Rhino 1.3)

Q: How much is the regular price?
A: 295.-$ per license per year

Q: Do you have a connection for hdrlightsudio ? this is a great extra tool to light up your scene with customised HDR`s
A: No, but the HDR files generated by HDRStudio can be used directly in Iray. Iray allows you to adjust the intensity of the HDR file as well to match the brightness if there are any other existing lights in the scene.

Q: What GPU is used in the Demo?
A: 2 x Quadro M5000

Q: Can I have Iray render only a part of a picture?
A: Subregion rendering is not supported in Iray for Rhino 1.2

Q: Is there a downloadable free trial version of Iray for Rhino?
A: A 90-day trial can be found under

Q: Wondering how the daylight can be set up apart from the position, e.g. can you use Perez sky ?
A: Right now the sun and Sky simulation is a model that combines both sunlight and Skylight

Q: Will there be a version of Iray for Rhino OSX ?
A: For Iray for Rhino version 1.x not, but we are considering porting it to OSX for version 2.0

Q: Is there a library of Jewelery material ? Stones and metal (platinium / gold / silver ?)
A: Yes, contains among many others materials for Jewelry as well

Q: Any chance to see this working with RhinoMAC?

i think this was answered already, except you are still working on Mac OS 9 or similar :smiley:
but yeah i am also hoping for this.

Sorry. My bad. I just seen the answer. Thank you.

Too slowly rendering speed and too expansive
