Hello Everyone,

Could someone help me understand gain and value as they apply to emitting materials - both rgb and blackbody?

Thanks in advance!

Thanks again everyone, As far as Blender goes, if I am instancing, using the same mesh for several objects, I cannot apply the scaling. Meaning, if I scale an object that is using a shared mesh, I cannot apply the scale (ctrl a) such that the object would now have a scale factor of 1,1,1. If the obj...

Thanks everyone for the information! If I may, I'd like to tag on another question that is closely related. Scale for an object that has an emitting material applied: From a Blender perspective, I can scale the object, or I can scale the mesh (tab into edit mode, select all and scale). If I understa...

neo0., Thanks for the response! According to the documentation, "Mes light is deprecated, use emitting materials instead". While I have not tried each of the material types as an emitting material, I was wondering if there was any material that points tothe difference between a diffuse emitting mate...

Hello Everyone, A few questions on emitting materials. I am using Blender, and I noticed when exporting that although most material types can be an emitting material. With respect to lighting, is there any advantage to one type over the other? What is the difference in the emitted light for each mat...

OK Everybody, Here is where I put to rest any and all beliefs that I have an amazing grasp of the obvious. While desperately searching for a specific line of code that sets rgb for a diffuse shader, I finally got the ISL previewer to work on a windows machine (I normally use Ubuntu, and the graphics...

MSUdom5,

I have the program working on a win machine, but I have one question - every screenshot I have seen has 3 tabs - Albedo, Bump and Displace. When I run the program, all I see is Albedo. How do I get the other tabs?

Hello again, Here is some information I have put together. It is very basic, and will not be much help to most of you, but it is a start for the uninitiated. http://www.cdupload.com/files/45841_kcmop/Indigo_Shader_Diffuse_Albedo_Noise.pdf Here are a couple of observations - from a Blender / Blendigo...

Some material coming soon from me - not really a tutorial, just some information from poking around. I hope to expand it into tutorials eventually, but for now, it will just be information - most of which will be common knowledge to the majority of people, but new material for me and others like me.

I beat you to it. It appears as though halt time -1 is assumed unless otherwise specified, and overwritten by an include statement even thogh the included scene does not specifically set halt time. I added the following to the previewmats.igs: <renderer_settings> <halt_time>900</halt_time> </rendere...

Hello Everyone, I am doing some test renders for a document on ISL. I thought it would be best to use the same scene as the mat db. However, I would like to limit the render time for each test to 15 minutes. I have done this before with other scene files, but this one seems to ignore the setting. Do...

Done!

Very well then, I shall push on. Until such time as I can afford an upgrade.

I appreciate your help!!

I believe you are right...a quick google seems to suggest nvidia 5 or 6 and up is required. Are there any other options open to me?
