flcc Posted April 15, 2021 Share Posted April 15, 2021 (edited) Hi Something strange happen. Ocean Evaluate doesn't work anymore no matter which version of houdini I try. I try H16, H17, H175, H18, H185 Even the old file that worked generates an error. Diving into the node it appears that the probleme come from the ocean.h include in the Volume Wrangle named calc_X_Y_Z. Here is the type of error it generates : C:/PROGRA~1/SIDEEF~1/HOUDIN~1.499/houdini/vex/include/ocean.h: Invalid declaration type for variable X: complex (404,37) C:/PROGRA~1/SIDEEF~1/HOUDIN~1.499/houdini/vex/include/ocean.h: Invalid declaration type for variable Z: complex (404,40). ..... long list Does anyone have an idea ? [edit] While continuing to search, I tried on another machine that has a version of houdini and it's the same thing. The only common thing between these two machines is the windows update done in december. Does this speak to anyone?

Atom Posted April 15, 2021 Share Posted April 15, 2021 (edited) That's interesting. I was poking around inside of pdb_constraint.h today to try and find out why OpenCL has all of a sudden quit working on the GPU. I got a message that about variables not being defined as double precision. I wonder if some type of compile switch has been janked on these recent Houdini builds? (using H18.5.532) Edited April 15, 2021 by Atom Quote Link to comment Share on other sites More sharing options...
flcc Posted April 15, 2021 Author Share Posted April 15, 2021 (edited) As I said, in my case all Houdini versions are affected. I've udated my first post and I suspect something with Windows updates. In wich specific node can I find pdb_constraint.h ? I try a grain sim but I get no error. Edited April 15, 2021 by flcc Quote Link to comment Share on other sites More sharing options...
AslakKS Posted April 15, 2021 Share Posted April 15, 2021 Was there not a opencl bump to ocl3.0 with the nvidia driver recently? might be worth a shot to roll back Quote Link to comment Share on other sites More sharing options...
flcc Posted April 15, 2021 Author Share Posted April 15, 2021 (edited) From what I've seen OpenCl 3.0 support begin with driver 465. Don't know for Atom, but since I run 456 It doesn't seem to be the cause of my problem, but yes while I update windows I also update nvidia drivers. At same time I can't rollback due to redshift version ! Edited April 15, 2021 by flcc Quote Link to comment Share on other sites More sharing options...
rbowden Posted April 16, 2021 Share Posted April 16, 2021 This is one of those times where you should email support@sidefx.com as this problem seems a bit more complex. Quote Link to comment Share on other sites More sharing options...
