IES Tweeked and imported as an asset to new scene

[kimalbech]

The IES files I can get never seems to be visually right in a render - nor does the LUX values look right in an light analysis render. So here is what I do. I calculate the average LUX value on a floor from 3 meters height - I tweek the IES paramtere untill the Light analysis render shows a LUX value close to my calculations. Because I want to make realistic Light analysis renders AND normal renders with the same parameters I here after tweek Camera settings so the real light looks as I know the real lighting would look like. This part can not be calulated - It´s only my experience kicking in.

When I have done this work with an IES file for a specified Luminiare I will export the asset for later use in other cases with the same luminiare. Importing this assest into a new case gives me the IES with the tweeks I made earlier in my assest window. BUT HOW DO I GET THE ASSEST INTO MY SCENE ?? Have tried to click an drag any way - but can´t seem to get it into my scene window. Feeling stupid in Denmark any ideas anyone ?
In attached scene I made the assest Light Deco spot, and afterwards imported the asset "Alaska" - but can´t get it into my scene.

Hi kimalbech

Once the asset is loaded in the V-Ray Asset Editor, a component is created in SketchUp's Components tray as well. From there you can click-and-drag it into the scene.

georgi.georgiev ohhhh my God - how did I get so "brain-locked" into V-ray, that I totally forgot the V-Ray interaction with SU - that´s scary to say the least THANKS

Hi kimalbech,

I believe we could add a context menu option 'Add to Scene' for light and Geometry assets.
This will remove the need of locating the component in the model's components list.
Do you think this makes sense?

Would be great - but again, it´s a two headed Snake - increase or decrease interaction with SU from user perspective. Thanks konstantin_chaos

I use sketchup and vray for years and i couldn't get how i can use add light and add geometry option.. "Add to the scene" option is a good choise, but add where? Click and drag would be better in my opinion, if it is possible of course..

I'm using only IES files for my lighting calculations. So what would be awesome: if the symbol of the light could show the light distribution curve (either as a simple 3D mesh or the two main axes (C0-C180 and C90-C270 plane).
Now due to the fact that only the red arrow is shown, you first have to find out in which direction the light needs to be placed (especially for asymmetrical light distributions). Furthermore, the way the IES file is generated by the lighting manufacturers differs sometimes - when the physical light measurements is made with the luminaire upside down (which is sometimes necessary for huge lights), it can happen that the light distribution curve goes up - while the VRAY arrow points down. If it's hard to understand because of my English, please look at DIALUX EVO or RELUX software. Then the difference will be very clear.

This would be a big thing on my wishlist for future versions...
and a smaller thing for the wishlist: implement the use of the EULUMDAT (.LDT) format additionally to the IES standard, your European customers will love you for that

Thank you for your comment! I'll log a note for consideration of how to better represent non-standard IES files.
Regarding the support of .ldt files, I've already logged similar suggestions, however, for the time being this is not on the dev team's to-do list. If you wish to use .ldt files, please convert them to .ies using one of the available 3rd-party tools for that purpose.

Kind regards,
Peter
