VRay 6 Ocean

V-Ray V-Ray for Houdini General

Hi,

Very excited to see that ocean support has been added to VRay 6.
I am trying to get it working. I followed the video as close as possible, but it just doesn’t seem to render any displacement.

I have attached my hip file. It would be great if someone could point out what I have done wrong

Hey @Dubbie99 ,

When dealing with live meshes, they need to be packed prior to assigning a displacement material - that’s not just for the spectra but displacement in general.
Simply add a Pack SOP in the chain before the Material SOP and you should be good to go.

Best regards!

I still can’t seem to get it to render the ocean. It would be super helpful if you could provide a scene that works so I can look at it.

if I set the displ amount to 0.9 instead if 1, it now renders - however the scale seems completely off.

Here is the ocean preview which looks correct

Hey @Dubbie99 ,

I’ll double check with your scene over the weekend. I forgot to mention it in my previous post - there’s an example page in our documentation that shows some demo setups here: V-Ray for Houdini
It might be helpful to check out although the setup is fairly straightforward so it’s possible you’ve hit an issue. I’ll get back to you when I know more.

Best regards!

I found the sample scene and it worked. Still not sure why my original scene doesn’t work, I think it is set up the same.

thanks for the help
