IES lighting issue in vray next for sketchup

Hi, im new to rendering with vray next in sketchup. Every time i try and insert an ies lighting file it doesn’t work. It inserts the file, but when i render no light shows up in the render. Has anyone else had a similar issue with vray next ?

Thanks
Richard

IES lights are different from the lights included with V-Ray. Quick example, this is what an IES light that I just downloaded is supposed to look like from the manufacturer:
27walllight

This is what it looks like when imported and rendered. Nothing there right?

This is what it looks like when I enable Intensity and bump it up to ‘50,000’. Exact number varies but needs to be bumped waaaay up.

Hi Eric,

thanks for the quick response.

I have already tried that, but still it doesn’t work.

Would you mind sending me the ies file that you have just shown me please ?

Maybe its a dodgy file, i did try a few thought with the same result.

Many thanks

Richard

Private messaged you.

Actually I have facing some issues with Vray for sketchup, Whenever I Import the materials in vray but material are doesn’t show in vray liabrary, And second issue is whenever I used IES lights, Dome lights, Spot lights and Omni lights in models but whenever I go for rendering in vray the at time of rendering those lights are doesn’t show. Some lights are show

Can you share your model? If it’s too large in file size, then upload it somewhere like Google Drive, Dropbox, etc and share the link here.

You shouldn’t share your email, it’s against the forum rules because there are a lot of bots looking for them everywhere. For your safety delete it.

This is my model link, please check the file what issues with this.

I sent you the Google Drive link of my model, Please check it and solved my issues.

IES lights need high values in their intensity in in order to show up. Try either entering in a really high value…like 100,000 or more and see what happens.

You can also add the ‘light mix’ render element which allows you to change the intensity after render has completed in the Frame Buffer:

Here I have adjusted the intensity from 1 to 100x in the Frame Buffer and as you can see…the IES lights are showing up now:

I also recommend that you take our two free courses on V-Ray over at SketchUp Campus to learn more.

When I used your technique, but IES lights are showing like this, Please tell me sir what should I do?

Are you required to use IES lights? Spots or emissive materials may be easier to work with and get the same or better result.

You are right but this problem is not only with CS lights, also dome light, spot light and omni lights, they also are not show in render.

I just ‘wiped’ all of the V-Ray data from your model and replaced the lights fresh and new. They all seem to work fine for me. I can’t tell you unfortunately why they may not be showing up on your end.


You can try adding these lights into your model and see if they work. They should drop right into place so be sure to ‘paste in place’ after copying. Also, you may have to ‘repath’ to your own dome light or HDRI that you download from Chaos Cosmos.
