Hey Guys,

What would be the best approach on making an ocean shader in Vray?

Thanks

Use the ocean texture from Phoenix

[ivaylo.ivanov]

Yep, the Phoenix ocean texture seems to be the best option from the V-Ray textures currently.

[miguelortega]

can we use this texture without having phoenix? would be great, if so where can we get it?

Form "Create -> V-Ray -> Create From V-Ray Plugin -> Texture"

Phoenix Ocean shader will not work..
And I´ve no idea why.
Found the sample scene here:
http://forums.chaosgroup.com/showthr...=phoenix+ocean
Load it and render with the "A-result" (no waves)
Increase the Disp Amount to 10/-5 and get the "B-result" (all amplitute seems to work only horizontal)


What is wrong? Please help to get the correct result...
Thanks, Jörg
(Win7, Maya 2015, Vray 3.3.02 - the last official build)

Rotate your disp?

[Komposer]

rotate the place3D makes other strange results
thanks

Try using Vector Displacement (absolute) mode for Displacement type. As for the horizontal issue you can change that with the Velcoh value of the PhxShaderOceanTex.

hi Zdravko, that helps for the first. (image_A)

But when I scale the plane up to 10 (need much more space) then I get... (image_B)

First, the waves becomes a complete other look - it´s a 3dPlacement!!! and should be the same look, only bigger space!?
Second... and I get ugly black and brightBlue parts...
When I deactivate "View depentent" in the render tab, I get this result... (image_C)

The ugly black parts dissapears, but much more brightBlue parts appears... (image_D)
...and it has nothing to do with the reflections!

Please give me some hints, how I can archive a bigger ocean surface.
BTW...I played arround with Your horizon- hint..."Velcoh value of the PhxShaderOceanTex" and can not understand, what that mean...
...with the horizon it seems to do nothing.
Isn´t there any document for this hopefully shader?
I took a look into the phoenix 2.2 for Max help, but the most things are different to the Maya version.
Hopefully thanks for help, Jörg

How did you scale the plane? Try using ChannelBox instead. Here is an example scene: http://ftp.chaosgroup.com/support/phxoceantex1.ma
Also please keep in mind that the PhxShaderOceanTex texture options in Maya have different names. In example Velcoh correspond to Velocity coherence: http://docs.chaosgroup.com/display/P...enixFDOceanTex

hi Zdravko, thanks for the hint.
To scale the plane in the channelBox makes the job.
To scale the border edges do the job too.
Thanks for the sample scene.
