Hi

Im getting nutz.. I built the Hoover Dan, in construction in 1932 Colorado, entirely procedurally in Houdini,

All went fine until I started to do test rendering in Redshift with something different than a basic material with no texture.

I only use 2 differents materials, no displacement or anything fancy for now, quixel surface, and now Redshift is extremely SLOWWWWW to start showing the first pixel… like 8 time slower, more than 30min to start, or don’t even start sometimes…

What could I do ? What could be the issue? Idea?

 

Please help, I have no much hair left !

One thing you could try is to export all (or most complex) of your geometry as a .rs file, if you have not already. Then Redshift will read the geometry from the disk and not have to request the geometry through the Houdini API, which might be a single threaded process IDK. This API request might be part of the slowdown.

Thanks @Atom for the suggestion. Actualyl the main problem was Redshift could have some problem doing tangent computation for the normal bump. Best is to compute yourself and pass it to Redshift using a polyframe. The difference could be dramatic

Found another issue as well with the Lab import FBX which even is marked as hidden, obj remain visible.
