Cloud render issues with materials

[Anonymous]

Hi All,

I am a newbie to 3D and cloud rendering.

I am trying to do an interior design and it involves a lot of graphics (in the form of lightboxes) to be included so I turn on the self-illumination option in the materials editor. For most of the materials, it does work except for one particular lightbox. When I render on the cloud, it becomes a black void. No matter what I do (turn off self-illumination, increase luminance, decrease luminance etc) the blacked-out void is still there. The lightbox is at an angle which may explain the problem (as the other graphics are either flat or at 90deg). Can somebody suggest a work-around or let me know what I am doing wrong? I do notice that when I apply a material on an object and try to revolve it, the material behaves in strange ways. Can somebody also suggest what I need to do to ensure that when I apply material to an object, I can maintain its position on the object when revolving or moving the object.

I have attached screenshots for your information.

Thanks in advance!

Regards,

Bill

Hello Bill,

I am not sure where did you use the light box besiades the marked object and which light did you use for...

but you may want to check these documents.

http://docs.autodesk.com/ADSK360/help/ENU/rendering/index.html#!/url=./files/GUID-C567BD24-A967-429B... 

Why aren't some settings and RPC (Rich Photorealistic Content) objects in the rendering?

• Fog is not supported.
• Text and MText are not supported. Convert them to a mesh object before rendering.
• Standard lights (lightingunits=0) and distant lights are not supported; they are converted to Photometric lights.
• Default lights are not exported. If no explicit lights are in the scene, the rendering shows only the nonilluminated diffuse color of the objects.
• Shadow settings are ignored. Shadows are always ray traced.
• Background overrides (solid/gradient/image, sun/sky) are not supporte

Hi Soyoung,

Thank you for responding to my query!

All the images you see in the picture I have attached are self-illumated and I have set them up with the same settings which is why I am confused why I get a black void on that particular section.

Would it be best if I were to send the file to you?

Regards,

Bill.

Hi Bill,

Thank you for providing me the drawing file.

I examined it both in AutoCAD and at A360 Rendering(http://rendering.360.autodesk.com/), I found the material association has a problem.

Please watch this video.

When I opened the drawing file in AutoCAD, the linking was already broken, so I couldn't get the right render result in AutoCAD.

If you switch to another material you can render in AutoCAD and at A360.

This is the result image I've got from A360.

Thanks for that. But if I can send you the missing image could you have a look at it?

Here is the image

I am sorry, but this can't be done by just switching the image.

I recommend you to set up the environment/options meet to your expectation.

Sorry, I'm just new to 3D Autocad 😞

Could you please explain what you mean by setting up the environment/options?

You can find many tutorial resources on the internet.

I found this video at Youtube and it is quite good.
