Wonderful, thank you for that! I guessed correctly on the height query in that case. Luckily the blueprints are very well laid out, so it was easy to copy from.
As for the performance, I’ve managed to get to a decent place without nativizing to C++ which is preferable at this stage. Essentially I just modelled a new hull sim mesh with around 40 vertices, and only calculate the delta using the first 8 Gerstner waves in the sum up function. This gets pretty good results at this stage, though it’s not very scalable of course, something for me to assess later.
I’m going to drop you an email for another question regarding the wave spectra. Thank you again!
