Shadows do not show in V-ray render, why?

shubba81 · 4 Feb 2009, 01:26

I am using vray and sketchup, on screen in sketchup I can see the shadows but when I render it you cant see them, anyone know why?

Thanks

It would help if you posted your vray settings and told us which release that you are using.

I'm guessing you're using the original version. That version has a bug in it so the V-Ray sun isn't updated with the SU sun automatically. You have to go to the Environment section, click the M to view the properties for the Sun abd click Update. (Note, I some times had to do this procedure two times before it set.)

In SR1.0 it syncs automatically.

In SR1.5 the V-Ray sun is off by default so you have to tell V-Ray to use it when you start a new project.

As you see, the answer depends on the version you use, so it's a good idea to include that in your queries. As well as SU version.

I am using sketchup 7 with the latest vray plugin (SR1.5 I think). I have gone into the environment and in GI sky and backgroung clicked on the M and gone in and updated them, but my shadows still do not show. I have then gone in and checked the box that says override suns parameters but this doesnt work either. The sunlight source is set to default but there is nothing else that I can set this to.

Sorry if im being a bit stupid.

hm.. can you post screenshot of your scene as it's rendered? and your environment options?

shubba81 · 4 Feb 2009, 17:51

Hi, I have attached my latest render, a print screen of wat the shadows look like on screen in SU, and the environment settings for both the GI skylight and the background. I hope this is helpful, thanks for all the help.

Screen shot of shadows

You shouldn't need any multiplied of the Sky map.

I'm wondering, it could be the time of the day. What if you change the time of say in SU?

Maybe this...

shubba81 · 4 Feb 2009, 21:36

I changed the time of day and I also did what arspi suggested, it seems to have worked. Thanks to you both.

I have the same problem but when I did the following steps, did not solve my problem! any idea?

syd_rawsky · 3 Jun 2017, 23:34

I'm having the same issue, but I only got the newest V-ray and I'm not familar with the last layout. I've attached an image, you can see the shadows casted in the sketchup model, but for some reason its not showing in the V-ray buffer. I've even tried buffering the entire scene, and nothing. Please help!
