Hello,
i use the displace map from oceanevaluate.but in octane it seems no work to the grid.
what's wrong with my setup?

The problem can be the file format. Probably Octane doesn't support .pic textures. Can you please export them to another common format (.jpg, .tif, etc.) and try again?

Thanks,

hello
i tried someother formats . the .tif looks better. i changed the gamma to 1. it's a greathelp .
but i have some other problems. the miscellaneous blocks on the picture. What can I do to solve the problem .the normal?

thank you !

Hmm, have you tried to adjust the ray epsilon parameter in the kernel node? I wonder if you could have a scale problem. If you want to share the scene including the displacement map, I could take a look at it here.

hello
i tried the epsilon but the problem still exists ,here is the scene.

thank you!

Sorry for the late reply. Please, disable the "Auto bump map" option in the vertex displacement node. Probably this feature doesn't work fine with the vector displacement maps.

Hello,
It is very strongly recommended to work with OpenEXR in 32-bit floating point precision (not for everything, though! For Displacement it is, at least) rather than TIFF or any (other) integer file formats.
