draganbaja Posted July 14, 2017 Share Posted July 14, 2017 How can I use ocean spectra with Redshift, it there a way to use baked spectra cache in redshift shader? Quote Link to comment Share on other sites More sharing options...
Audrey Posted August 14, 2017 Share Posted August 14, 2017 Did you find your answer? I am currently doing an ocean simulation with Redshift and I am very interested in the answer! Quote Link to comment Share on other sites More sharing options...

mz2 Posted September 19, 2017 Share Posted September 19, 2017 In case someone else gets stuck on something as silly as I did: I've tried following instructions in the H16 ocean masterclass (creating the UV attribute with the ocean evaluation node, baking a displacement map with that node, and displacing the evaluated geometry with the map in Redshift) but I was stupidly using a TIF to store it, presumably clamping the displacement values to [0…1]. Switching to EXR made it all work happily… Quote Link to comment Share on other sites More sharing options...

Assigbed redshift obj parameter, enabled displacement. Created a texture(used the displacement map) and displace and assigned it into displacement. And Assigned dl the shader to the grid. Still nothing! What am I doing wrong? Thank you.. Quote Link to comment Share on other sites More sharing options...

Try to add UV Texture node after the grid and everything should be fine. Quote Link to comment Share on other sites More sharing options...
PJM33 Posted October 15, 2018 Share Posted October 15, 2018 Hey guys! So I followed your steps: I baked the mantra ocean uv spectra and assigned it and displaced it to a redshift shader and assigned the 'ocean surface' node to render with the newly assigned redshift shader that has the mantra displacement and I'm still not getting anything to come up on my oceans. I also enabled the Tessellation and Displacement. I've been working on this for days and tried so many things and can't get it to go. Would you be kind enough to take a look at my scene and see if you can spot what's gone wrong? I really appreaciate your help!

scorpes Posted October 17, 2018 Share Posted October 17, 2018 Would be nice to be able to use redshift with the procedural spectra map instead of a baked one... Quote Link to comment Share on other sites More sharing options...

P SmallOceanTestv02.hiplc I checked out your project file and although you created UVs, the purple render flag is set to the grid without UVs. If you you set the render flag to the ocean preview node by pressing Control+Left Click it will work. Quote Link to comment Share on other sites More sharing options...
cloudlung Posted July 14, 2020 Share Posted July 14, 2020 Hi Guys I'm pretty new to Houdini and have run into a little stretching issue after following the steps here. I have attached an image showing this. Any idea what I'm doing wrong? Thanks in advance Quote Link to comment Share on other sites More sharing options...
