Vray next ies light problem

[agentorange_cg]

Have been using Vray Next in Sketchup Pro 2018 on a MacBook Pro running macOS High Sierra 10.13.6 and have a problem with the IES Light. Built the model applied IES lights, rendered fast and what I wanted to achieve. When I come to reopen the file one of three things happen.... lights are there and as saved, they have turned red and are really tiny or they have totally gone missing, yet the IES light can be seen in the V-Ray Asset Editor.

This is beginning to be a bit of pain as I'm having to replace the IES lights every time I need to Render.


Any help on this problem would be appreciated.

Hi,

Could you please do the following:

Start SketchUp and open the Ruby Console. Then load the project, open the Asset Editor, and see if any messages are output in the Ruby Console. If so, please copy the contents to a text file and share it with us.
Afterwards, open the VFB and the V-Ray Progress window (bottom-right button in the VFB) and then start a render. Please provide a full copy of the V-Ray Progress window, once the render is done, in a text file as well.

Additionally, has the filed been saved with V-Ray Next? Are you able to reproduce the issue consistently with other files as well?

Well tried this and nothing appeared in the Ruby Console and once again my lights have disappeared from my file yet they're in the Asset Editor.
Attached is the Vray progress images can't seem to copy and paste it as a Text file...hope all this helps. You can see the render in the background without the IES lighting really sharp edges.

Same problem here. Created a bunch of IES lights and every time I saved, closed and reopened the skp file the IES light component geometry got smaller and smaller. Eventually they just disappeared! But they still render, the group they're in is still selectable (but uneditable as there's no visible geometry to right-click on) and they're still in V-Ray's Asset Editor. Working in Windows 10, SU18.

Hi,

Thank you for the feedback!

Kindly note that our developers have resolved this issue and the solution has been implemented in the upcoming hotfix update.

In the meantime, the following one liner resolves the issue. Please note that the project needs to be saved afterwards, otherwise the issue would be reproducible.

Sketchup.active_model.set_attribute("VRayInfo", "version", 40000)

Hi agentorange_cg,

Can you please download and test the latest V-Ray build from our web-page:
chaosgroup.com

Your issue should no longer be reproducible with the latest version.
If it still persists, please share an example file that causes it and we will investigate.

Regards,
Konstantin
