Elumdat (LDT) files in Twinmotion

Hello,

While looking for lm and K info about my lights I found that most of the providers, at least here in Europe, provide an Elumudat (LDT) file with information about the light sources.

I haven't found anything in the forum about it. Is it there a way to configure lights using Elumdat in Twinmotion?

Thanks

About Elumidat:

An LDT file is a luminaire (light fixture) data file created for use with DIALux, a professional lighting planning application. It defines the lighting parameters of a luminaire, including its number of lamps, light intensity, light distribution curve, and size.

Hello ,

Thank you for posting your question in the community and at this time this file format is not supported with lights objects in Twinmotion. You can however use IES profiles which are more commonly used worldwide from my understanding.

Here is a video tutorial I found to convert LDT files into IES files:

If you think this is something that is going to have a big impact to have this file type supported with light sources you can submit an idea on our road-map for consideration: https://portal.productboard.com/7pu88c9kpmqtzt8hwg6arujh/tabs/4-under-consideration

Hope this helps.

Kind regards,

Hello ,

Thank you very much for your response and the video.

Most of the providers I find here in Spain provide only the LDT file, but if there is a conversion path and internatinally IES is more used then I guess it is good as it is.

Thanks
