Lumenrt and Microstation Light sources

If anyone can help it would be appreciated, I have been experimenting with lighting a complex scene with Microstation and Lumenrt 15.

A microstation light source with a cone angle of 90 degrees is the maximum allowed, this appears in Lumenrt to equate to a cone angle of 45 degrees.

Although one can adjust intensity and on off of named light groups in LRT one cannot adjust the other characteristics as a group, it needs to be done individually which is not practical with a large number of lights.

It would be great is one could group lights in LRT and if the microstation lights where on a different level from LRT lights. (the attached file show the problem)PDF

  • Hi Pinky,
     
    Thanks for getting back to me on this, I look forward to update 16. I have tried both of the workarounds you suggest with limited success for the following reasons, it is difficult to select multiple light sources even using the CTRL tab among other reasons, because the selected light doesn’t change colour. Dragging a box around them only works if all the other levels are turned off (I have over 100). It would be worthwhile all the trouble doing one of these things if I could then group the lights into single object for changing the characteristics and moving them, but this is not possible. Could you add a group function ?
     
    I am looking forward to testing Omniverse and have, for the first time, created an i-model, can you let me know how to import it into Omniverse at some point.
     
    Thanks again.
     
    Best Wishes

  • Hi Martin,

    In regards to making selections, you can get more control by using the Hierarchy panel and moving it to the other side. This keeps the Hierarchy panel it onscreen while using other tools. Through this panel you can select items from a list instead of graphically. This is often times easier although the interface is small and quite fiddly, but so is the rest of the LumenRT interface.

    This short video shows the process I use. (For clarity keystrokes & mouse buttons are overlayed at the top of video)

    Hopefully this is helpful.

    Regards,
    Ron
