VrayDisplacementMod and Vantage - Making waves!

[harald_martinoff]

Hi

We are using the VrayDisplacementMod constantly in our projects to get good looking ocean (no simulation needed) with foam and waves and so. We really want to go over to Vantage (using 3dsmax and Vray now) for rendering, but even if I read that the newest Vantage is supporting Displacement (is that correct?) we are not able to get the ocean water we need.
The setup is the standard setup with PhoenixFDOcean plugged into the VrayDisplacementMod and also plugged into PhoenixFDFoam in materials for the foam. We can live without the foam, but the good waves of this setup is essential!
What will the correct way be, to get this to work in Vantage?

Found out that I can plug in PhoenixFDOcean into the normal Displacement modifier so that works, but to get a proper ocean waves I need so many faces on the ocean plan. It makes my scene heavy! Is there any plan to implement the VrayDisplacementMod into Vantage so we can use less faces and also get the foam effect in through its use in Material?

Our next update will have a new option that reduces displacement memory usage for large objects like this, as long as the base mesh has at least some tessellation (not just 2 triangles).

I think I misunderstood. You're baking the displacement inside 3ds Max, before it reaches V-Ray/Vantage. We can't reduce the triangles in this case. Vantage doesn't support Phoenix plugins.

Thanks NPG
Will it be some support of this in the future? It is not a big problem as long as I can drive the PhoenixFDOcean through the Max Displacement modifier.

We use VrayDirt to use Ambient Occlusion to create some foam where objects (Vessels) interact with the Ocean. I see it has been a discussion to implement VrayDirt supported by Vantage, but I also understand that if Vantage support every part of Vray then at a point it will be no differences between those two and then Vantage will be slow and not a real option beside Vray.

As such do anyone know an idea to how to make a foam line where our Vessels go into water (something like in the image) in Vantage?

is regular vray displacement modifier now working properly in Vantage? always seems like no matter what it does not look correct

[npg]

Can you be more specific? What issue are you having? Vantage supports displacement.

Hi, this for example, good displacement map and nothing and i know this map works well

Hi mitviz,

What Tessellation level setting in Edit>Preferences>Render Defaults? Can you share your scene to investigate it on our end?

Best regards,
Alexander

Try setting displacement tessellation to High in Edit->Preferences and enable "per-triangle tessellation level". Also if your wall is made up of just a couple of triangles, try pre-tessellating it Max.

[mitviz]

ok will try those, will also share the scene

ok i think its ok now, I didn't realise you are not using the displacement modifier but rather the displacement in the material's node itself
