I find a solution for my problem

I create a new material in blender just with color white and emit 100%
and after I choose in blendigo a emmiter material and its good to export

Don't work here

Quick question: Can I use material from Schott Glass Material Library from blendigo or do I have to edit XML file for it?

You can choose an external material
then you indicate the path of the file .igm (.igml)

If it doesn't work, I don't know

yep, tried that already, it doesn't work witch igml library. Or mayby I don't know how tu use it, tried like that: library.igml\materialName.

Hey SmartDen, thank you for the great exporter. I have run into a bit of a problem, but I don't know if it has been fixed and I just need to download it again or if it's something new. In the materials tab, when I preview, I have to set the UV Set to "default" for the sphere preview, all of the others require it to be set to "uv". And when you do the actual render all of them need to be set to "uv". It's no biggie, just frustrating when I want to preview with the sphere.

Uhm...
You always need to use the UV-mapping channel, as else, Indigo wouldn't know, how to use the texture...
The only exception is the (Texturizable) sphere-primitive, which needs to be set on Orco, so that the texture gets mapped over it.
Not a Blendigo thingy (at least, if I got you right) but an Indigo thingy and surely no bug

Thanks Kram,

It's probably something I'm doing wrong. But if what you say is true, then it would be nice if Blendigo handled this transparently so I don't have to keep changing the UV set manually every time I want to preview with the sphere primitive. It is really a pain with blended materials.

Hum... is the sphere preview no sphere primitive?
Maybe it isn't... As it's set up for allowing textures and it was "invented" before sphere primitives actually got texturizeable...
So, the easiest way would be, to rebuild the scene and change the sphere to a primitive.... (This would also slightly decrease rendertimes as such a sphere can be handled faster than a highpoly monster

Hello everyone,

Thanks for creating and publishing the great script Blendigo for v1.0, I love it. I'm enjoying using the Indigo renderer with it now and it works well so smoothly, what a cool script it is!

I like the way of linking materials to objects rather than meshes in Blender, selecting the button OB as you can see in the image below, and I always do that when modelling.

However, it was found that the script didn't work well for linking materials to objects. I tried rendering with Indigo after doing that and got a render in which the materials were ignored.

I really needed the ability that the script can understand the links of materials to objects, so I have modified the script and here is that.

All that you have to do to use the modified script is to replace the file blendigo_v104.py to the downloaded one. What do you think of it?

I hope it can be implemented as a formal version in the development.

Thanks.

Thanks for your version Hans. Excuse my ignorance, but what difference or what advantage does it offer to link materials to objects? I just tried pressing the "ob" option in one of my materials and all its options and settings disappeared. Does this affect when rendering with internal? So I guess your suggestion is only for the blendigo material editor?

regards,
Alvaro

Thanks for your reply, afecelis.

Yeah, only pressing the OB button will make nothing. After pressing it, you have to choose your material in the box above the OB button in the same way. Actually, I will delete the link to the mesh first by clicking the X button, and then press the OB button and choose a material in the box to link it only to the object.

You will get the same render with Blender internal when using the ME option and when using the OB option. My version will help only those who use the OB option.

afecelis wrote:but what difference or what advantage does it offer to link materials to objects?

The difference is not so big and it is only the difference of the data structure in Blender. The advantage to link materials to objects is to save the memory for meshes in modelling. When you want to use a lot of objects and the same mesh, you will link them to the mesh by pressing Alt+D key to duplicate the link, and when you want to use different materails for the objects, it would be better to link the material to each object using the OB button.

But it might be a minority opinion. Could I have the possibility to do that in the next version of Blendigo...

what should it good for?

Kram1032 · Post by **Kram1032** » Mon Jan 21, 2008 12:14 am

The big disadvanatge I found, is that you only can use a single material per object. It surely saves some memory, though, as the material doesn't have additional informations about which part of the mesh has which material...

It's like this:
OB -> "The object with THIS name has the material with THAT name"
ME -> "The face # XYZ on the object with THIS name has the material with THAT name"

(Though, I guess, the advantage isn't that big and I always use ME)

Thanks for your reply, SmartDen.

It is a bit hard for me to tell you clearly what it is good for, because it is not a story that can be seen visually in a render, but the major reason why it is needed is that I want to use many objects that have the same mesh but that should have different materials. In such a situation, if you use the OB option, you don't have to duplicate the mesh in order to use the different materials... and that's all.

It may not be a big advantage enough to motivate all of you to take a consideration for the implementation, but it would be happy if I can use the OB option in Blendigo as well as in Blender.
