Hi guys,


I downloaded Houdini 15 and Im learning about dynamics sims. I have a hipnc file with a fluid simulation working but it is too slow, so Im trying to write the simulation to disk by the output node, but when I hit the Save to Disk button nothing happens. I also tried hitting the Save to Disk in Background, but same issue, the Render Scheduler Pane marks the job as “done”, but no sim file appears in the location to be written.

Why is this happening? Am I missing any step for saving my sim to disk?


Thank you very much!

Hm, I'm not sure why this didn't work. Did you save the Houdini scene file before clicking save? The default paths uses $HIP. This has a sensible default only when your scene file is saved. If you middle click on the output file parameter, it should show you what the evaluated path is. Is the path valid?

Hi there,

Yeah I saved the hipnc file and I created a project for this also. When I click on the Save to Disk in Background, if I hadnt saved the file it pops out a window telling me that I must save the file first, I save the file, hit again and it appears another window, the render scheduler pane I guess, but the job appears as “done”, and no files are written. I also review the path for the files to be written, and it is correct, I mean the $HIP is created and all the folders specified in the path of the Output node; by the way, I dont know what the expression $HIPNAME.`opname(“..”)`.$SF.sim means, but if I middle click on the output file parameter, thae path that appears it is valid.

Is allowed to write sim files this way in Apprentice?

Thanks a lot

Looks like I spoke too soon. The Output DOP uses the Dynamic ROP internally, which has always been disabled for Apprentice (and Indie) users. However, it seems this restriction no longer makes sense, so we'll remove it in the next daily build (15.0.326).

Oh!!

That should be why! jejeje


Thanks a lot! Ill be waiting for the next daily build!!


Thank you again for the support!!!
